Calling a C# method from JavaScript

Question

I want to to call a method GetAccount from my controller AccountController.cs, in my JavaScript factory LoginFactory.js. Something like this:

AccountController.cs:

public Account GetAccount(string userName)
    { ... }

LoginFactory.js:

if(x>y) {
   var account = <%AccountController.GetAccount(someParam);%>
}

I've tried using [WebMethod] and Ajax, but I can't get it to work: I get a 404 response.

Could you please post the code of your Ajax request? And did you check this post? — Tachyon

You cannot call a method directly from client side to server side. Instead, use a service or WebMethod. You are claiming that this doesn't work, so please post the code that is failing, both javascript and C# otherwise it will be hard to determine whats wrong. — Daniel B

If you're getting a 404, almost certainly, your webservice is not deployed onto the server you're hitting or you're hitting the wrong server. I'd look at a Fiddler/Firebug trace to see that it's going to the correct path for your IIS server. — Jeff Watkins

Assuming your GetAccount method can be reached at /Account/GetAccount when your application runs, you could use the following:

$.ajax({
  type: 'GET',
  url: '/Account/GetAccount',
  data: { 'username' : 'a-username' },
  dataType: 'json',
  success: function(jsonData) {
    alert(jsonData);
  },
  error: function() {
    alert('error');
  }
});

Note - this is dependant on jQuery.

This causes the browser to make a request to /Account/GetAccount as if you had done so by entering the URL in the URL bar, but of course, captures the returned json for use in your client side (javascript) script.

If this returns a 404, it would be worth checking your routing.
