@Url in Mvc4. Action How to read the value of a JavaScript variable

JS in   function Search()  {      var businessDate = GetSelectedBusinessDate( "#businessYear" ,  "#businessMonth" );      var ul= ‘  @Url.Action("Query", "FileImport", new { BusinessDate = businessDate })‘      $( ‘#dg‘ ).datagrid({ url: url }); }The value of businessdate needs to be obtained from getselectedbusinessdate, but the above code does not seem to be executing, prompting:
The name "Businessdate" solution does not exist in the current context function Search () {
var businessdate = getselectedbusinessdate ("#businessYear", "#businessMonth");
var url = ' @Url. Action ("Query", "fileimport") ' + '?businessdate= "+businessdate;
$ (' #dg '). DataGrid ({Url:url});
} <iframe src= "@Html.raw(Url.action ("Edit", "Home", new {@Id=13,@Name= "Lizikang"}) "></iframe>, <iframe src=" @Html.raw(Url.action ("Edit", "Home", new {id=13,name= "Lizikang"})) "></iframe> Suppose your Url is
ABC/EFG? Aa=bb&cc=dd&&eefff=aaa "
You can write that.
Url.action ("EFT", "ABC") +? Aa=bb&cc=dd&&eefff=aaa "
If you must use the official
Can write like this public RouteValueDictionary ParseQueryStringToRouteValues( string queryString)          {              var parsed = HttpUtility.ParseQueryString(queryString);              Dictionary< string ,  object > querystringDic = parsed.AllKeys                  .ToDictionary(k => k, k => ( object )parsed[k]);              return new RouteValueDictionary(querystringDic);          } var url = Url.Action( "eft" , "ABC" ,ParseQueryStringToRouteValues( "AA=bb&cc=dd&&eefff=aaa" )) ; 用 new {} 形式好像不行, 至少用 return RedirectToAction( "CouponGrant" , ParseQueryStringToRouteValues( "Couponid=" + cg.CouponId)); 取不到参数
