我扩展了Sujoy的代码来组成一个函数。

/**

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;
}

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。

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 }

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 : '');
                    }

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;
