获取url参数

var urlQuery=function () {
    var result = {};
    if (location.href.indexOf('?') != -1) {
        var str = location.href;
        var num = str.indexOf('?');
        str = str.substr(num + 1);
        var data = str.split('&');
   
        for (var i = 0; i < data.length; i++) {
            num = data[i].indexOf('=');            
            if (num > 0) {
                name = data[i].substr(0, num);
                value = data[i].substr(num + 1);
                result[name] = value;
            }
        }
       
    }
    return result;
