我认为你需要查询插件。

例如:

window.location.search = jQuery.query.set("rows", 10);

不管行当前的状态如何，这都可以工作。

Ben Alman有一个很好的jquery querystring/url插件，可以让你很容易地操纵querystring。

如要求-

点击这里进入他的测试页面

在firebug中，在控制台中输入以下内容

jQuery.param.querystring (window.location。报道中,x = 3&newValue = 100);

它将返回以下修改后的url字符串

http://benalman.com/code/test/js-jquery-url-querystring.html?a=3&b=Y&c=Z&newValue=100#n=1&o=2&p=3

注意，a的查询字符串值已从X更改为3，并添加了新值。

然后你可以使用新的url字符串，但你希望 使用文档。location = newUrl或改变一个锚链接等

一个可行的替代字符串操作的方法是建立一个html表单，只修改rows元素的值吗?

html就像是

<form id='myForm' target='site.fwx'>
    <input type='hidden' name='position' value='1'/>
    <input type='hidden' name='archiveid' value='5000'/>
    <input type='hidden' name='columns' value='5'/>
    <input type='hidden' name='rows' value='20'/>
    <input type='hidden' name='sorting' value='ModifiedTimeAsc'/>
</form>

使用下面的JavaScript提交表单

var myForm = document.getElementById('myForm');
myForm.rows.value = yourNewValue;
myForm.submit();

可能不适合所有情况，但可能比解析URL字符串更好。

你也可以通过普通的JS来实现

var url = document.URL
var newAdditionalURL = "";
var tempArray = url.split("?");
var baseURL = tempArray[0];
var aditionalURL = tempArray[1]; 
var temp = "";
if(aditionalURL)
{
var tempArray = aditionalURL.split("&");
for ( var i in tempArray ){
    if(tempArray[i].indexOf("rows") == -1){
            newAdditionalURL += temp+tempArray[i];
                temp = "&";
            }
        }
}
var rows_txt = temp+"rows=10";
var finalURL = baseURL+"?"+newAdditionalURL+rows_txt;

我写了一个小的帮助函数，它适用于任何选择。你所需要做的就是将类"redirectOnChange"添加到任何选择元素，这将导致页面重新加载一个新的/更改的querystring参数，等于选择的id和值，例如:

<select id="myValue" class="redirectOnChange"> 
    <option value="222">test222</option>
    <option value="333">test333</option>
</select>

上面的例子会加上“?”myValue=222"或"?myValue=333”(如果存在其他参数，则使用“&”)，然后重新加载页面。

jQuery:

$(document).ready(function () {

    //Redirect on Change
    $(".redirectOnChange").change(function () {
        var href = window.location.href.substring(0, window.location.href.indexOf('?'));
        var qs = window.location.href.substring(window.location.href.indexOf('?') + 1, window.location.href.length);
        var newParam = $(this).attr("id") + '=' + $(this).val();

        if (qs.indexOf($(this).attr("id") + '=') == -1) {
            if (qs == '') {
                qs = '?'
            }
            else {
                qs = qs + '&'
            }
            qs = qs + newParam;

        }
        else {
            var start = qs.indexOf($(this).attr("id") + "=");
            var end = qs.indexOf("&", start);
            if (end == -1) {
                end = qs.length;
            }
            var curParam = qs.substring(start, end);
            qs = qs.replace(curParam, newParam);
        }
        window.location.replace(href + '?' + qs);
    });
});

我扩展了Sujoy的代码来组成一个函数。

/**
 * http://stackoverflow.com/a/10997390/11236
 */
function updateURLParameter(url, param, paramVal){
    var newAdditionalURL = "";
    var tempArray = url.split("?");
    var baseURL = tempArray[0];
    var additionalURL = tempArray[1];
    var temp = "";
    if (additionalURL) {
        tempArray = additionalURL.split("&");
        for (var i=0; i<tempArray.length; i++){
            if(tempArray[i].split('=')[0] != param){
                newAdditionalURL += temp + tempArray[i];
                temp = "&";
            }
        }
    }

    var rows_txt = temp + "" + param + "=" + paramVal;
    return baseURL + "?" + newAdditionalURL + rows_txt;
}

函数调用:

var newURL = updateURLParameter(window.location.href, 'locId', 'newLoc');
newURL = updateURLParameter(newURL, 'resId', 'newResId');

window.history.replaceState('', '', updateURLParameter(window.location.href, "param", "value"));

更新版本，也照顾到URL上的锚。

function updateURLParameter(url, param, paramVal)
{
    var TheAnchor = null;
    var newAdditionalURL = "";
    var tempArray = url.split("?");
    var baseURL = tempArray[0];
    var additionalURL = tempArray[1];
    var temp = "";

    if (additionalURL) 
    {
        var tmpAnchor = additionalURL.split("#");
        var TheParams = tmpAnchor[0];
            TheAnchor = tmpAnchor[1];
        if(TheAnchor)
            additionalURL = TheParams;

        tempArray = additionalURL.split("&");

        for (var i=0; i<tempArray.length; i++)
        {
            if(tempArray[i].split('=')[0] != param)
            {
                newAdditionalURL += temp + tempArray[i];
                temp = "&";
            }
        }        
    }
    else
    {
        var tmpAnchor = baseURL.split("#");
        var TheParams = tmpAnchor[0];
            TheAnchor  = tmpAnchor[1];

        if(TheParams)
            baseURL = TheParams;
    }

    if(TheAnchor)
        paramVal += "#" + TheAnchor;

    var rows_txt = temp + "" + param + "=" + paramVal;
    return baseURL + "?" + newAdditionalURL + rows_txt;
}

这是对苏乔伊回答的另一种说法。刚刚改变了变量名，并添加了一个命名空间包装:

window.MyNamespace = window.MyNamespace  || {};
window.MyNamespace.Uri = window.MyNamespace.Uri || {};

(function (ns) {

    ns.SetQueryStringParameter = function(url, parameterName, parameterValue) {

        var otherQueryStringParameters = "";

        var urlParts = url.split("?");

        var baseUrl = urlParts[0];
        var queryString = urlParts[1];

        var itemSeparator = "";
        if (queryString) {

            var queryStringParts = queryString.split("&");

            for (var i = 0; i < queryStringParts.length; i++){

                if(queryStringParts[i].split('=')[0] != parameterName){

                    otherQueryStringParameters += itemSeparator + queryStringParts[i];
                    itemSeparator = "&";
                }
            }
        }

        var newQueryStringParameter = itemSeparator + parameterName + "=" + parameterValue;

        return baseUrl + "?" + otherQueryStringParameters + newQueryStringParameter;
    };

})(window.MyNamespace.Uri);

现在的用法是:

var changedUrl = MyNamespace.Uri.SetQueryStringParameter(originalUrl, "CarType", "Ford");

您可以使用我的这个库来完成这项工作:https://github.com/Mikhus/jsurl

var url = new Url('site.fwx?position=1&archiveid=5000&columns=5&rows=20&sorting=ModifiedTimeAsc');
url.query.rows = 10;
alert( url);

快速的纯js小解决方案，不需要插件:

function replaceQueryParam(param, newval, search) {
    var regex = new RegExp("([?;&])" + param + "[^&;]*[;&]?");
    var query = search.replace(regex, "$1").replace(/&$/, '');

    return (query.length > 2 ? query + "&" : "?") + (newval ? param + "=" + newval : '');
}

这样叫它:

 window.location = '/mypage' + replaceQueryParam('rows', 55, window.location.search)

或者，如果你想保持在同一页上并替换多个参数:

 var str = window.location.search
 str = replaceQueryParam('rows', 55, str)
 str = replaceQueryParam('cols', 'no', str)
 window.location = window.location.pathname + str

Luke:要完全删除参数，为值传递false或null: replaceQueryParam('rows'， false, params)。因为0也是假的，所以指定'0'。

四年后，在我学到了很多东西之后，来回答我自己的问题。特别是你不应该对所有事情都使用jQuery。我已经创建了一个简单的模块，可以解析/stringify查询字符串。这使得修改查询字符串变得很容易。

query-string的用法如下:

// parse the query string into an object
var q = queryString.parse(location.search);
// set the `row` property
q.rows = 10;
// convert the object to a query string
// and overwrite the existing query string
location.search = queryString.stringify(q);

我也写了一个库获取和设置URL查询参数在JavaScript。

下面是它用法的一个例子。

var url = Qurl.create()
  , query
  , foo
  ;

获取查询参数作为对象，通过键，或添加/更改/删除。

// returns { foo: 'bar', baz: 'qux' } for ?foo=bar&baz=qux
query = url.query();

// get the current value of foo
foo = url.query('foo');

// set ?foo=bar&baz=qux
url.query('foo', 'bar');
url.query('baz', 'qux');

// unset foo, leaving ?baz=qux
url.query('foo', false); // unsets foo

我也在找同样的东西，发现:https://github.com/medialize/URI.js，这是相当不错:)

- - -更新

我找到了一个更好的包:https://www.npmjs.org/package/qs，它还处理get参数中的数组。

我是这么做的。使用我的editParams()函数，你可以添加，删除或更改任何参数，然后使用内置的replaceState()函数更新URL:

window.history.replaceState('object or string', 'Title', 'page.html' + editParams('sorting', ModifiedTimeAsc));


// background functions below:

// add/change/remove URL parameter
// use a value of false to remove parameter
// returns a url-style string
function editParams (key, value) {
  key = encodeURI(key);

  var params = getSearchParameters();

  if (Object.keys(params).length === 0) {
    if (value !== false)
      return '?' + key + '=' + encodeURI(value);
    else
      return '';
  }

  if (value !== false)
    params[key] = encodeURI(value);
  else
    delete params[key];

  if (Object.keys(params).length === 0)
    return '';

  return '?' + $.map(params, function (value, key) {
    return key + '=' + value;
  }).join('&');
}

// Get object/associative array of URL parameters
function getSearchParameters () {
  var prmstr = window.location.search.substr(1);
  return prmstr !== null && prmstr !== "" ? transformToAssocArray(prmstr) : {};
}

// convert parameters from url-style string to associative array
function transformToAssocArray (prmstr) {
  var params = {},
      prmarr = prmstr.split("&");

  for (var i = 0; i < prmarr.length; i++) {
    var tmparr = prmarr[i].split("=");
    params[tmparr[0]] = tmparr[1];
  }
  return params;
}

在这里，我引用了Adil Malik的回答，并修正了我认为的3个问题。

/**
 * Adds or updates a URL parameter.
 *
 * @param {string} url  the URL to modify
 * @param {string} param  the name of the parameter
 * @param {string} paramVal  the new value for the parameter
 * @return {string}  the updated URL
 */
self.setParameter = function (url, param, paramVal){
  // http://stackoverflow.com/a/10997390/2391566
  var parts = url.split('?');
  var baseUrl = parts[0];
  var oldQueryString = parts[1];
  var newParameters = [];
  if (oldQueryString) {
    var oldParameters = oldQueryString.split('&');
    for (var i = 0; i < oldParameters.length; i++) {
      if(oldParameters[i].split('=')[0] != param) {
        newParameters.push(oldParameters[i]);
      }
    }
  }
  if (paramVal !== '' && paramVal !== null && typeof paramVal !== 'undefined') {
    newParameters.push(param + '=' + encodeURI(paramVal));
  }
  if (newParameters.length > 0) {
    return baseUrl + '?' + newParameters.join('&');
  } else {
    return baseUrl;
  }
}

一种现代的方法是使用基于URLSearchParams的本地标准。所有主流浏览器都支持它，除了IE，因为IE提供了腻子

const paramsString = "site.fwx?position=1&archiveid=5000&columns=5&rows=20&sorting=ModifiedTimeAsc"
const searchParams = new URLSearchParams(paramsString);
searchParams.set('rows', 10);
console.log(searchParams.toString()); // return modified string.

我知道这是一个老问题。我增强了上面的功能，以添加或更新查询参数。仍然是一个纯JS解决方案。

                      function addOrUpdateQueryParam(param, newval, search) {

                        var questionIndex = search.indexOf('?');

                        if (questionIndex < 0) {
                            search = search + '?';
                            search = search + param + '=' + newval;
                            return search;
                        }

                        var regex = new RegExp("([?;&])" + param + "[^&;]*[;&]?");
                        var query = search.replace(regex, "$1").replace(/&$/, '');

                        var indexOfEquals = query.indexOf('=');

                        return (indexOfEquals >= 0 ? query + '&' : query + '') + (newval ? param + '=' + newval : '');
                    }

我的函数支持删除参数

function updateURLParameter(url, param, paramVal, remove = false) {
        var newAdditionalURL = '';
        var tempArray = url.split('?');
        var baseURL = tempArray[0];
        var additionalURL = tempArray[1];
        var rows_txt = '';

        if (additionalURL)
            newAdditionalURL = decodeURI(additionalURL) + '&';

        if (remove)
            newAdditionalURL = newAdditionalURL.replace(param + '=' + paramVal, '');
        else
            rows_txt = param + '=' + paramVal;

        window.history.replaceState('', '', (baseURL + "?" + newAdditionalURL + rows_txt).replace('?&', '?').replace('&&', '&').replace(/\&$/, ''));
    }

这是更改URL参数的现代方法:

function setGetParam(key,value) {
  if (history.pushState) {
    var params = new URLSearchParams(window.location.search);
    params.set(key, value);
    var newUrl = window.location.origin 
          + window.location.pathname 
          + '?' + params.toString();
    window.history.pushState({path:newUrl},'',newUrl);
  }
}

     // usage: clear ; cd src/js/node/js-unit-tests/01-set-url-param ; npm test ; cd -
     // prereqs: , nodejs , mocha
     // URI = scheme:[//authority]path[?paramName1=paramValue1&paramName2=paramValue2][#fragment]
     // call by: uri = uri.setUriParam("as","md")
     String.prototype.setUriParam = function (paramName, paramValue) {
        var uri = this
        var fragment = ( uri.indexOf('#') === -1 ) ? '' : uri.split('#')[1]
        uri = ( uri.indexOf('#') === -1 ) ? uri : uri.split('#')[0]
        if ( uri.indexOf("?") === -1 ) { uri = uri + '?&' }
        uri = uri.replace ( '?' + paramName , '?&' + paramName)
        var toRepl = (paramValue != null) ? ('$1' + paramValue) : ''
        var toSrch = new RegExp('([&]' + paramName + '=)(([^&#]*)?)')
        uri = uri.replace(toSrch,toRepl)
        if (uri.indexOf(paramName + '=') === -1 && toRepl != '' ) {
           var ampersandMayBe = uri.endsWith('&') ? '' : '&'
           uri = uri + ampersandMayBe + paramName + "=" + String(paramValue)
        }
        uri = ( fragment.length == 0 ) ? uri : (uri+"#"+fragment) //may-be re-add the fragment
        return uri
     }

        // add a new param name , param value pair
        it('http://org.com/path?prm=src_v&other_p=other_v#f -> http://org.com/path?&prm=tgt_v&other_p=other_v#f', function (){
           var uri = 'http://site.eu:80/qto/view/devops_guide_doc?&other_p=other_v#f'
           var uriExpected = 'http://site.eu:80/qto/view/devops_guide_doc?&other_p=other_v&bid=foo-bar#f'
           var uriActual = uri.setUriParam("bid","foo-bar")
           assert.equal(uriActual, uriExpected);
        });

     });

我的解决方案:

const setParams = (data) => {
    if (typeof data !== 'undefined' && typeof data !== 'object') {
        return
    }

    let url = new URL(window.location.href)
    const params = new URLSearchParams(url.search)

    for (const key of Object.keys(data)) {
        if (data[key] == 0) {
            params.delete(key)
        } else {
            params.set(key, data[key])
        }
    }

    url.search = params
    url = url.toString()
    window.history.replaceState({ url: url }, null, url)
}

然后调用“setParams”并传递一个带有你想设置的数据的对象。

例子:

$('select').on('change', e => {
    const $this = $(e.currentTarget)
    setParams({ $this.attr('name'): $this.val() })
})

在我的情况下，我必须更新html选择输入时，它的变化，如果值是“0”，删除参数。如果对象键为“null”，则可以编辑该函数并从url中删除参数。

希望这对你们有帮助

2020解决方案:设置变量，如果传入null或undefined，则删除iti。

var setSearchParam = function(key, value) {
    if (!window.history.pushState) {
        return;
    }

    if (!key) {
        return;
    }

    var url = new URL(window.location.href);
    var params = new window.URLSearchParams(window.location.search);
    if (value === undefined || value === null) {
        params.delete(key);
    } else {
        params.set(key, value);
    }

    url.search = params;
    url = url.toString();
    window.history.replaceState({url: url}, null, url);
}

我只是写了一个简单的模块来处理读取和更新当前url查询参数。

使用示例:

import UrlParams from './UrlParams'

UrlParams.remove('foo') //removes all occurences of foo=?
UrlParams.set('foo', 'bar') //set all occurences of foo equal to bar
UrlParams.add('foo', 'bar2') //add bar2 to foo result: foo=bar&foo=bar2
UrlParams.get('foo') //returns bar
UrlParams.get('foo', true) //returns [bar, bar2]

下面是我的代码UrlParams.(js/ts):

class UrlParams {

    /**
     * Get params from current url
     * 
     * @returns URLSearchParams
     */
    static getParams(){
        let url = new URL(window.location.href)
        return new URLSearchParams(url.search.slice(1))
    }

    /**
     * Update current url with params
     * 
     * @param params URLSearchParams
     */
    static update(params){
        if(`${params}`){
            window.history.replaceState({}, '', `${location.pathname}?${params}`)
        } else {
            window.history.replaceState({}, '', `${location.pathname}`)
        }
    }

    /**
     * Remove key from url query
     * 
     * @param param string
     */
    static remove(param){
        let params = this.getParams()
        if(params.has(param)){
            params.delete(param)
            this.update(params)
        }
    }

    /**
     * Add key value pair to current url
     * 
     * @param key string
     * @param value string
     */
    static add(key, value){
        let params = this.getParams()
        params.append(key, value)
        this.update(params)
    }

    /**
     * Get value or values of key
     * 
     * @param param string
     * @param all string | string[]
     */
    static get(param, all=false){
        let params = this.getParams()
        if(all){
            return params.getAll(param)
        }
        return params.get(param)
    }

    /**
     * Set value of query param
     * 
     * @param key string
     * @param value string
     */
    static set(key, value){
        let params = this.getParams()
        params.set(key, value)
        this.update(params)
    }

}
export default UrlParams
export { UrlParams }

没有库，使用URL() WebAPI (https://developer.mozilla.org/en-US/docs/Web/API/URL)

function setURLParameter(url, parameter, value) {
    let url = new URL(url);
    if (url.searchParams.get(parameter) === value) {
        return url;
    }
    url.searchParams.set(parameter, value);
    return url.href;
}

这在IE: https://developer.mozilla.org/en-US/docs/Web/API/URL#Browser_compatibility上不起作用

如果您想在地址栏中更改url:

const search = new URLSearchParams(location.search);
search.set('rows', 10);
location.search = search.toString();

注意，改变位置。搜索重新加载页面。

URL查询参数可以使用URLSearchParams和History接口轻松修改:

// Construct URLSearchParams object instance from current URL querystring.
var queryParams = new URLSearchParams(window.location.search);
 
// Set new or modify existing parameter value. 
//queryParams.set("myParam", "myValue");
queryParams.set("rows", "10");
 
// Replace current querystring with the new one.
history.replaceState(null, null, "?"+queryParams.toString());

或者，我们可以使用pushState()方法来创建一个新的历史条目，而不是使用replaceState()修改当前的历史条目:

history.pushState(null, null, "?"+queryParams.toString());

下面是一个使用query-string库的简单解决方案。

const qs = require('query-string')
function addQuery(key, value) {
  const q = qs.parse(location.search)
  const url = qs.stringifyUrl(
    {
      url: location.pathname,
      query: {
      ...q,
      [key]: value,
      },
    },
    { skipEmptyString: true }
  );
  window.location.href = url
  // if you are using Turbolinks
  // add this: Turbolinks.visit(url)
}
// Usage
addQuery('page', 2)

如果你使用react而不使用react-router

export function useAddQuery() {
  const location = window.location;
  const addQuery = useCallback(
    (key, value) => {
      const q = qs.parse(location.search);
      const url = qs.stringifyUrl(
        {
          url: location.pathname,
          query: {
            ...q,
            [key]: value,
          },
        },
        { skipEmptyString: true }
      );
      window.location.href = url
    },
    [location]
  );

  return { addQuery };
}
// Usage
const { addQuery } = useAddQuery()
addQuery('page', 2)

如果你使用react和react-router

export function useAddQuery() {
  const location = useLocation();
  const history = useHistory();

  const addQuery = useCallback(
    (key, value) => {
      let pathname = location.pathname;
      let searchParams = new URLSearchParams(location.search);
      searchParams.set(key, value);
      history.push({
        pathname: pathname,
        search: searchParams.toString()
      });
    },
    [location, history]
  );

  return { addQuery };
}

// Usage
const { addQuery } = useAddQuery()
addQuery('page', 2)

PS: qs是从query-string模块导入的。

使用URLSearchParams检查，获取并设置参数值为URL

下面是获取当前URL并设置新参数并根据需要更新URL或重新加载页面的示例

var rows = 5; // value that you want to set
var url = new URL(window.location);
(url.searchParams.has('rows') ? url.searchParams.set('rows', rows) : url.searchParams.append('rows', rows));

url.search = url.searchParams;
url        = url.toString();

// if you want to append into URL without reloading the page
history.pushState({}, null, url);

// want to reload the window with a new param
window.location = url;

使用javascript URL:

var url = new URL(window.location);
(url.searchParams.has('rows') ? url.searchParams.set('rows', rows) : url.searchParams.append('rows', rows));
window.location = url;

想想这个例子:

const myUrl = new URL("http://www.example.com?columns=5&rows=20");
myUrl.searchParams.set('rows', 10);
console.log(myUrl.href); // http://www.example.com?columns=5&rows=10
myUrl.searchParams.set('foo', 'bar'); // add new param
console.log(myUrl.href); // http://www.example.com?columns=5&rows=10&foo=bar

它会做和你要求的完全一样的事情。请注意URL必须有正确的格式。在你的例子中，你必须指定协议(http或https)

var url = new URL(window.location.href);
var search_params = url.searchParams;
search_params.set("param", value);
url.search = search_params.toString();
var new_url = url.pathname + url.search;
window.history.replaceState({}, '', new_url);

在URLSearchParams文档中，有一种非常干净的方法可以做到这一点，而且不会影响历史堆栈。

// URL: https://example.com?version=1.0
const params = new URLSearchParams(location.search);
params.set('version', 2.0);

window.history.replaceState({}, '', `${location.pathname}?${params}`);
// URL: https://example.com?version=2.0

类似地，删除参数

params.delete('version')
window.history.replaceState({}, '', `${location.pathname}?${params}`);
// URL: https://example.com?

let url= new url ("https://example.com/site.fwx?position=1&archiveid=5000&columns=5&rows=20&sorting=ModifiedTimeAsc") url.searchParams。设置(“行”,10) console.log (url.toString ())
