Pass Parameter to JavaScript

I'm trying to pass two parameters to a JavaScript function. Unfortunately this give me error.

Here is the function

    function load(do,div)
    {
        var do;
        var div;
        document.getElementById('spinner').innerHTML = '<img src=\'/images/spinner.gif\'>';
        $('#'+div).load('rpc.php?'+do,
        function()
        {
            document.getElementById('spinner').innerHTML = '';
            $('#'+div).show('slow');
        }
    }

And I call it like this:

    <a href="javascript:;" onclick="load('limit','mydiv');">Get Limit</a>

How can I fix that?

do is a reserved word in JavaScript. Change the variable name to something else. Additionally, don't re-declare the arguments in the function body. So remove the 2 var lines from the top of your function body.

If you're curious what the do keyword is for, it's for do...while loops where the condition is evaluated at the end, not the beginning of the loop. It's used something like this:

do {
    // do stuff in loop at least once
} while (some_condition_is_true);

Is it because you are redefining do div again in function and they are overriding the scope of passed parameters?
