将url的查询参数解析成字典对象

function getQueryObject(url) {

    url = url == null ? window.location.href : url;

    var search = url.substring(url.lastIndexOf("?") + 1);

    var obj = {};

    var reg = /([^?&=]+)=([^?&=]*)/g;

    search.replace(reg, function (rs, $1, $2) {

        var name = decodeURIComponent($1);

        var val = decodeURIComponent($2);               

        val = String(val);

        obj[name] = val;

        return rs;

    });

    return obj;

}

 

getQueryObject("http://www.cnblogs.com/leee/p/4456840.html?name=1&dd=ddd**")

Object {name: "1", dd: "ddd**"}
