Passing parameter to AJAX function from HTML

Question

This seems like the most stupid question, but I cannot get this to work. I want to pass a parameter into my AJAX function from my HTML button. Code looks like:

<input type="button" onclick="signupAjax(1)" value="Sign up>

My AJAX function:

function signupAjax(int select)
{
....
//for test purposes
alert(select);
}

For whatever reason, the parameter isn't getting passed into the AJAX function. Seems pretty basic, but can't seem to get it to work.

I know there's no actual AJAX code there, the actual code works perfectly well. It would just make life easier if I could pass this parameter.

Yeah that's worked. Why don't I need to declare a type for that parameter? — Scott

because it is all var there isn't an int in JS just a var it is all object oriented. — abc123

cause its a scripting language with dynamic typing, search "dynamic typing" if you want more info about it — x4rf41

DEMO: http://jsfiddle.net/abc123/vnP4J/

Description: no need to say int select just select it is all objects in JS, next you missed a " in the input at the end.

CODE:

<script type='text/javascript'>
    function signupAjax(select)
    {
        //for test purposes
        alert(select);
    }
</script>
<input type="button" onclick="signupAjax(1)" value="Sign up" />

Notes: One this isn't AJAX nor is it ASYNC it is just an onclick event. It will be called synchronously. Inside this function some AJAX/ASYNC call could happen and it would work just fine.

The function definition should be

function signupAjax(select)
{
....
//for test purposes
alert(select);
}
