jquery ajax posting

Hey all, I cannot seem to get a simple ajax working between a php page and jquery. I have followed a few tutorials. but having trouble actually understanding what is actually going on.

Javascript (JQuery)

$(function(){
    $('#trigger').click(function(){
        askajax;
    });

    function askajax(){
        $.post("ask.php",{ question: "canuseeme" } ,function(data)
        {
          if(data=='yes')
          {
            alert("answer is yes");
          }
          else
          {
            alert("answer is no");
          }
       });
    }
});

The PHP:

if($_POST['question']){
    echo "yes";
} else {
    echo "no";
}

Any ideas guys?

EDIT: THANKS TO @Jacob

$('#trigger').click(function(){

        alert("doing ajax"); // THIS SHOWS
        $.post("as开发者_Python百科k.php",{ question: "canuseeme" }, function(data)
        {
          if(data=='yes')
          {
            alert("answer is yes"); // THIS DOESNT
          }
          else
          {
            alert("answer is no"); // THIS DOESNT
          }
       });
    });

This'll work:

$('#trigger').click(askajax);

Or this:

$('#trigger').click(function() {
   askajax();
});

But I prefer to do it this way:

$(function(){
    $('#trigger').click(function(){
        $.post("ask.php",{ question: "canuseeme" } ,function(data)
        {
          if(data=='yes')
          {
            alert("answer is yes");
          }
          else
          {
            alert("answer is no");
          }
       });
    });
});

Reason being that you don't ever use the askajax function again, and it will only be defined in the ready function's scope, so why even bother with a standalone function definition? Just use an anonymous function and be done with it. :)

On line 3, change askajax; to askajax();
