JavaScript RegExp method to get address bar parameters (object-oriented)_js object-oriented

Copy code The code is as follows:

Request = {
QueryString : function(item){
var svalue = location.search.match(new
RegExp('[?&]' item '=([^&]*)(&?)','i'));
return svalue ? svalue[1] : svalue;
}
}
var key = Request.QueryString('key');

Is Request.QueryString very similar to ASPNET and JAVA? ?
