js 获取请求地址中的参数

js中如何获取浏览器请求地址中的参数呢?

js获取请求的query string

var getPageParams = function(){
            var i,ilen,strs,keyName,keyValue,
                    params={},
                    path = window.location.pathname,
                    url = window.location.href;
            if(url.indexOf("?")>-1){
                var index=url.indexOf("?");
                strs=url.substring(index+1);
                console.log(strs);
                strs=strs.split("&");
                ilen=strs.length;
                for(i=0;i<ilen;i++){
                    var indexEqual=strs[i].indexOf(‘=‘);
                    keyName=strs[i].substring(0,indexEqual);
                    keyValue=strs[i].substring(indexEqual+1);
                    if(keyName=="callback") keyValue=decodeURIComponent(keyValue);
                    params[keyName]=keyValue;
                }
            }
           
            return params;
        };
        console.log(getPageParams());

请求地址为:http://localhost:63342/chanjet_web_js/chanjet/js/test_whuang.html?callback=http://www.weixin.com?id=123&app=weixin

时,运行结果:

Object {callback: "http://www.weixin.com?id=123", app: "weixin"}

http://localhost:63342/chanjet_web_js/chanjet/js/test_whuang.html?callback=http://www.weixin.com?id=123&app=weixin&returnurl=http://www.baidu.com?

运行结果:
