If you need to return JSON, you will $.ajax in DataType: "JSON"

Backstage: Public Jsonresult ajaxgetcoupon (formcollection fm,int IDs) {

Return Json (New {Errcode =0,message= "very sorry"});

}

Page Pass Parameter

Location.href = "order/submitorder?sku=" + SKU + "&g=" + Groupbuyid;

Public ActionResult SubmitOrder (string sku, int count = 1, int c = 0, int g = 0, String viewName = "SubmitOrder")
{

Shoppingcartinfo cartinfo = new Shoppingcartinfo ();

Return base. View (ViewName, cartinfo);
}
