Question

If I want to call a server function from JavaScript to retrieve a name of a person from a database (just as an example)… and I went…

name = myServices.getName(userId);

If I have a script manager with a service reference to a .asmx file that has the web method getName( int userId ) {} then this function should be called properly and would, eventually, return the name for that userId.

Unfortunately, I want to do…

name = myServices.getName(userId);
alert(name);

however, when doing ASP.NET AJAX, it would call the web method and continue executing before waiting for a response from the server (which I understand is the point of AJAX, to stop the browser from freezing while waiting for data)

I need to get the name back from the server before I can continue executing… How can I approach this to fix this issue?

Answer 1

There is a method you can add as a parameter to the service method that will call the method on success where you can do other stuff.

For example:

function test() {
    PageMethods.MyMethod("name", OnMyMethodComplete);
}

function OnMyMethodComplete(result, userContext, methodName) {
    alert(result);
}
