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;
}

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);

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());

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);
    });
});

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);
