javascript 地址变量吗 js修改url地址

js修改网址URL参数后实现刷新和不刷新

//获取URL参数
        function GetQueryString(name) {
            var reg = new RegExp("(^|&)" + name + "=([^&]*)(&|$)");
            var r = window.location.search.substr(1).match(reg);
            if (r != null) {
                return decodeURI(r[2]);
            }
            return null;
        };
        //name=参数名称，val=参数值，isRefresh=是否刷新（0不刷新，1刷新）
        //使用方法：replaceParamVal("id", "888", 0)
        function replaceParamVal(name, val, isRefresh) {
            var url = this.location.href.toString();
            //console.log(url);
            var pattern = "[\?]" + name + '=([^&]*)';
            var pattern2 = "[&]" + name + '=([^&]*)';
            var replaceText = name + '=' + val;
            var replaceText1 = "\?" + replaceText;
            var replaceText2 = "&" + replaceText;
            if (url.match(pattern)) {
                var tmp = '/\\?(' + name + '=)([^&]*)/gi';
                var nUrl = url.replace(eval（tmp), replaceText1);;
            } else if (url.match(pattern2)) {
                var tmp = '/&(' + name + '=)([^&]*)/gi';
                var nUrl = url.replace(eval（tmp), replaceText2);;
            }
            else {
                if (url.match('[\?]')) {
                    var nUrl= url + '&' + replaceText;
                } else {
                    var nUrl= url + '?' + replaceText;
                }
            }
            if (isRefresh) {
                window.location.href = nUrl
            }
            var stateObject = { id: "" };
            var title = "";
            history.replaceState(stateObject, title, nUrl);
        }
        $(function () {
            $("#test1").click(function () {
                replaceParamVal("id", "333", 0)//不刷新
            })
            $("#test2").click(function () {
                replaceParamVal("id", "555", 1)//刷新
            })
        })
        document.write(GetQueryString("id"))

 

成功一定有方法，失败一定有原因。
