Question

我试图使用JQuery Ajax GET方法调用MVC控制器操作，并传递这两个参数。问题是操作没有被触发而是给出404错误。下面是我的代码，请指出我缺少的内容。

控制器中的动作

[HttpGet]
public JsonResult GetViewGridData(List<Models.ItemModel> gridData, int Category_Id = 0, int SubCategory_Id = 0)
{    
    //code goes here
}

Ajax调用

var Category_Id = $("#CategoryView").val();
var SubCategory_Id = $("#SubCategoryView").val();
$.ajax({
    url: "/Item/GetViewGridData/",
    data: {Category_Id:Category_Id,SubCategory_Id:SubCategory_Id},
    type: "GET",
    dataType: "JSON",
    success: function (data) {
        //});
    },
    error: function (data) {
    }
});

Answer 1

试试这个

function GetViewGridData() {
var Category_Id = $("#CategoryView").val();
var SubCategory_Id = $("#SubCategoryView").val();
    jQuery.ajax({
        url: '/GetViewGridData/Item?SubCategory_Id='+ SubCategory_Id +'& Category_Id='+ Category_Id,
        method: "GET",
        cache: false
    }).done(function (result) {
        //You will get the data in result
    });
}

Answer 2

转到属性路由 - 在路由配置中启用它 routes.MapMvcAttributeRoutes()

并在您的Item控制器中

[RoutePrefix("item")]
public class ItemController: Controller
{
  [HttpGet]
  [Route("GetViewGridData")]
  public JsonResult GetViewGridData(List<Models.ItemModel> gridData, int   Category_Id = 0, int SubCategory_Id = 0)
  {    
    //code goes here
  }
}

正如@Stephen评论的那样，如果你不使用它，也要从动作中删除不需要的参数

在控制器中调用GET操作的Ajax没有调用
