MVC中的控制器方法未调用

Question

I got quite a simple JS-Method:

<script language="javascript">   
    function AmountChanged(callingTextbox) {                 
        var enteredQuantity = callingTextbox.value;
        $.getJSON("/Catalog/GetEnteredQuantity",
        {
            id: enteredQuantity
        },
        function (data) {
            alert(data.MoneyText);                
        });
    }
</script>

This "should" call a function in my Controller:

public partial class CatalogController : BaseController {
    [HttpPost]
    public JsonResult GetEnteredQuantity(object id)
    {
        var result = new { MoneyText = "kost nix" };
        return Json(result);
    }
}

Through Chrome I can see that the JavaScript function is called. The debugger steps through until the line $.getJSON("/Catalog/GetEnteredQuantity", and then jumps to the last closing bracket of that JS-Function. But the GetEnteredQuantity()-Method is never called.

The console shows a "http://localhost:2451/Catalog/GetEnteredQuantity?id=48 404 Not Found"

What is wrong here?

Answer 1

Remove the HttpPost attribute from the action

public partial class CatalogController : BaseController {
    [HttpPost] //Remove it
    public JsonResult GetEnteredQuantity(object id)
    {
        var result = new { MoneyText = "kost nix" };
        return Json(result);
    }
}
