这个答案只是ellemayo的答案的一个小调整。它将自动更新URL，而不只是返回更新后的字符串。

function _updateQueryString(key, value, url) {
    if (!url) url = window.location.href;

    let updated = ''
    var re = new RegExp("([?&])" + key + "=.*?(&|#|$)(.*)", "gi"),
        hash;

    if (re.test(url)) {
        if (typeof value !== 'undefined' && value !== null) {
            updated = url.replace(re, '$1' + key + "=" + value + '$2$3');
        } 
        else {
            hash = url.split('#');
            url = hash[0].replace(re, '$1$3').replace(/(&|\?)$/, '');
            if (typeof hash[1] !== 'undefined' && hash[1] !== null) {
                url += '#' + hash[1];
            }
            updated = url;
        }
    }
    else {
        if (typeof value !== 'undefined' && value !== null) {
            var separator = url.indexOf('?') !== -1 ? '&' : '?';
            hash = url.split('#');
            url = hash[0] + separator + key + '=' + value;
            if (typeof hash[1] !== 'undefined' && hash[1] !== null) {
                url += '#' + hash[1];
            }
            updated = url;
        }
        else {
            updated = url;
        }
    }

    window.history.replaceState({ path: updated }, '', updated);
}

我想要的是:

使用浏览器的本地URL API 可以添加、更新、获取或删除吗 期望在散列之后的查询字符串，例如对于单页应用程序

function queryParam(options = {}) { var defaults = { method: 'set', url: window.location.href, key: undefined, value: undefined, } for (var prop in defaults) { options[prop] = typeof options[prop] !== 'undefined' ? options[prop] : defaults[prop] } const existing = (options.url.lastIndexOf('?') > options.url.lastIndexOf('#')) ? options.url.substr(options.url.lastIndexOf('?') + 1) : '' const query = new URLSearchParams(existing) if (options.method === 'set') { query.set(options.key, options.value) return `${options.url.replace(`?${existing}`, '')}?${query.toString()}` } else if (options.method === 'get') { const val = query.get(options.key) let result = val === null ? val : val.toString() return result } else if (options.method === 'delete') { query.delete(options.key) let result = `${options.url.replace(`?${existing}`, '')}?${query.toString()}` const lastChar = result.charAt(result.length - 1) if (lastChar === '?') { result = `${options.url.replace(`?${existing}`, '')}` } return result } } // Usage: let url = 'https://example.com/sandbox/#page/' url = queryParam({ url, method: 'set', key: 'my-first-param', value: 'me' }) console.log(url) url = queryParam({ url, method: 'set', key: 'my-second-param', value: 'you' }) console.log(url) url = queryParam({ url, method: 'set', key: 'my-second-param', value: 'whomever' }) console.log(url) url = queryParam({ url, method: 'delete', key: 'my-first-param' }) console.log(url) const mySecondParam = queryParam({ url, method: 'get', key: 'my-second-param', }) console.log(mySecondParam) url = queryParam({ url, method: 'delete', key: 'my-second-param' }) console.log(url)

是的，我有一个问题，我的查询字符串会溢出和复制，但这是由于我自己的懒惰。所以我玩了一点，并研究了一些js jquery(实际上是sizzle)和c#魔法。

所以我才意识到，在服务器已经完成了传递的值，这些值不再重要，没有重用，如果客户端想做同样的事情，显然它将总是一个新的请求，即使它是相同的参数被传递。这些都是客户端，所以一些缓存/cookie等在这方面可能很酷。

JS:

$(document).ready(function () {
            $('#ser').click(function () {
                SerializeIT();
            });
            function SerializeIT() {
                var baseUrl = "";
                baseUrl = getBaseUrlFromBrowserUrl(window.location.toString());
                var myQueryString = "";
                funkyMethodChangingStuff(); //whatever else before serializing and creating the querystring
                myQueryString = $('#fr2').serialize();
                window.location.replace(baseUrl + "?" + myQueryString);
            }
            function getBaseUrlFromBrowserUrl(szurl) {
                return szurl.split("?")[0];
            } 
            function funkyMethodChangingStuff(){
               //do stuff to whatever is in fr2
            }
        });

HTML:

<div id="fr2">
   <input type="text" name="qURL" value="http://somewhere.com" />
   <input type="text" name="qSPart" value="someSearchPattern" />
</div>
<button id="ser">Serialize! and go play with the server.</button>

C#:

    using System.Web;
    using System.Text;
    using System.Collections.Specialized;

    public partial class SomeCoolWebApp : System.Web.UI.Page
    {
        string weburl = string.Empty;
        string partName = string.Empty;

        protected void Page_Load(object sender, EventArgs e)
        {
            string loadurl = HttpContext.Current.Request.RawUrl;
            string querySZ = null;
            int isQuery = loadurl.IndexOf('?');
            if (isQuery == -1) { 
                //If There Was no Query
            }
            else if (isQuery >= 1) {
                querySZ = (isQuery < loadurl.Length - 1) ? loadurl.Substring(isQuery + 1) : string.Empty;
                string[] getSingleQuery = querySZ.Split('?');
                querySZ = getSingleQuery[0];

                NameValueCollection qs = null;
                qs = HttpUtility.ParseQueryString(querySZ);

                weburl = qs["qURL"];
                partName = qs["qSPart"];
                //call some great method thisPageRocks(weburl,partName); or whatever.
          }
      }
  }

好的，批评是受欢迎的(这是一个夜间调制，所以请随时注意调整)。如果这有帮助的话，竖起大拇指，快乐编码。

没有重复，每个请求都是唯一的，因为你修改了它，并且由于它的结构，很容易从dom内动态添加更多的查询。

给出Gal和tradyblix建议的修改window.location.search的代码示例:

var qs = window.location.search || "?";
var param = key + "=" + value; // remember to URI encode your parameters
if (qs.length > 1) {
    // more than just the question mark, so append with ampersand
    qs = qs + "&";
}
qs = qs + param;
window.location.search = qs;

使用此函数可以添加、删除和修改URL中的查询字符串参数

/**
@param String url
@param object param {key: value} query parameter
*/
function modifyURLQuery(url, param){
    var value = {};

    var query = String(url).split('?');

    if (query[1]) {
        var part = query[1].split('&');

        for (i = 0; i < part.length; i++) {
            var data = part[i].split('=');

            if (data[0] && data[1]) {
                value[data[0]] = data[1];
            }
        }
    }

    value = $.extend(value, param);

    // Remove empty value
    for (i in value){
        if(!value[i]){
            delete value[i];
        }
    }

    // Return url with modified parameter
    if(value){
        return query[0] + '?' + $.param(value);
    } else {
        return query[0];
    }
}

添加新的和修改现有参数的url

var new_url = modifyURLQuery("http://google.com?foo=34", {foo: 50, bar: 45});
// Result: http://google.com?foo=50&bar=45

删除现有的

var new_url = modifyURLQuery("http://google.com?foo=50&bar=45", {bar: null});
// Result: http://google.com?foo=50

我知道这是相当旧的，但我想把我的工作版本在这里。

function addOrUpdateUrlParam(uri, paramKey, paramVal) { var re = new RegExp("([?&])" + paramKey + "=[^&#]*", "i"); if (re.test(uri)) { uri = uri.replace(re, '$1' + paramKey + "=" + paramVal); } else { var separator = /\?/.test(uri) ? "&" : "?"; uri = uri + separator + paramKey + "=" + paramVal; } return uri; } jQuery(document).ready(function($) { $('#paramKey,#paramValue').on('change', function() { if ($('#paramKey').val() != "" && $('#paramValue').val() != "") { $('#uri').val(addOrUpdateUrlParam($('#uri').val(), $('#paramKey').val(), $('#paramValue').val())); } }); }); <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <input style="width:100%" type="text" id="uri" value="http://www.example.com/text.php"> <label style="display:block;">paramKey <input type="text" id="paramKey"> </label> <label style="display:block;">paramValue <input type="text" id="paramValue"> </label>
