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'。

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");

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;

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);

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)

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 }
