JS获取QueryString(Jquery)

    QueryString = {  
        data: {},  
        Initial: function() {  
            var aPairs, aTmp;  
            var queryString = new String(window.location.search);  
            queryString = queryString.substr(1, queryString.length); //remove   "?"     
            aPairs = queryString.split("&");  
            for (var i = 0; i < aPairs.length; i++) {  
                aTmp = aPairs[i].split("=");  
                this.data[aTmp[0]] = aTmp[1];  
            }  
        },  
        GetValue: function(key) {  
            return this.data[key];  
        }  
    }  

//先初始化  
QueryString.Initial(); 

    //例:获得名为deliverQty的参数值  
    var deliverQty = parseInt(QueryString.GetValue(‘deliverQty‘));
