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;

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());

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;

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);
    });
});

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;

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);
  }
}
