Assign a Javascript function to AjaxOptions OnSuccess property raise an error - ASP.NET MVC

Question

I'm using the Ajax.ActionLink helper to generate a link to delete a record. This is the code:

Ajax.ActionLink("Delete Image", "DeleteImage", new { id = item.Id },
                                               new AjaxOptions { HttpMethod = "Delete", OnSuccess = "Test()" } )

I'm assign a Javascript function (Test()) to the OnSucess property because I want to do some JQuery stuff, but when I click the Delete link this error message is raised

Microsoft JScript runtime error: 'b' is null or not an object

in the MicrosoftAjax.js file (Line 5, Column 62099). If I remove the OnSuccess property, everything works fine (even if the Test() function is empty, the same error is raised). Thanks for your help!

Answer 1

OnSuccess = "Test()" 

you have to write it like this it is a callback...

OnSuccess = "Test"

Answer 2

If you have to pass any parameter to the OnSuccess event you may have to write the funcion in this way.

OnSuccess = "function(){exampleFunction('" + param1 + "');}"

Answer 3

To pass a parameter, an anonymous function won't work, you need to do something like this:

OnSuccess = String.Format("Test({0})", param)
