I have a code:

XML

public JsonResult getDetailsProduct(string id)
       {
           return this.Json(new { detPro = "trung" });
       }

and Json function:

function showPMuaHang(pid) {
    var url = '/ShoppingCart/' + pid + '/getDetailsProduct';
    $.ajax({ type: "POST", url: url,
        success: function (data) {
            document.getElementById("popup_muahang").innerHTML = data.detPro;
        }
    })

And i use a href to call Json:

<a onclick="#" href="javascript:showPMuaHang('70')">Mua hàng</a>

If i click "a" in local.../Index page, Json return "trung" but if i call it from local.../ShoppingCart/, Json return "trung" but i it show "undefined".

I'm coding a website in MVC.

Hi,

Please modify your javascript function as follows :

function showPMuaHang(pid) {
           var url = '/ShoppingCart/getDetailsProduct/' + pid;

   $.ajax({
      type: "POST",
      url: url,
      success: function (data) {
      document.getElementById("popup_muahang").innerHTML = data.detPro;
      }
  })
}

problem is with url - your path is as follows -

/ShoppingCart/' + pid + '/getDetailsProduct'

where pid - 70
but you dont have 70 as your action or method.In URL '

getDetailsProduct

' is treated as " ID "

Following is the right format -

/ShoppingCart/getDetailsProduct/' + pid

which is -

/ShoppingCart/getDetailsProduct/70

It will goto ShoppingCartController and will serach for

getDetailsProduct

for the pid = 70

don't have any problem in

/ShoppingCart/' + pid + '/getDetailsProduct'

because i use route

"{controller}/{id}/{action}"

when i'm at index page, Json return "trung" but in other page, it return undefined.

Now, i know how to fix it.

function showPMuaHang(pid) {
    var url = '/ShoppingCart/' + pid + '/getDetailsProduct';
    $.ajax({ type: "POST", url: url,
        success: function (data) {
            data= JSON.parse(data);
            document.getElementById("popup_muahang").innerHTML = data.detPro;
        }
    })

if not in index page, i use : data = JSON.parse(data) when result return.
