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;
}

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");

我的函数支持删除参数

function updateURLParameter(url, param, paramVal, remove = false) {
        var newAdditionalURL = '';
        var tempArray = url.split('?');
        var baseURL = tempArray[0];
        var additionalURL = tempArray[1];
        var rows_txt = '';

        if (additionalURL)
            newAdditionalURL = decodeURI(additionalURL) + '&';

        if (remove)
            newAdditionalURL = newAdditionalURL.replace(param + '=' + paramVal, '');
        else
            rows_txt = param + '=' + paramVal;

        window.history.replaceState('', '', (baseURL + "?" + newAdditionalURL + rows_txt).replace('?&', '?').replace('&&', '&').replace(/\&$/, ''));
    }

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);

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 }
