Dynamically generate javascript using php

Question

I need to dynamically generate and execute some javascript on change of a select box. Right now, I am using a remote php file to generate that javascript (using mysql queries).

I don't know how then to run that javascript in my main page again. I've been playing around with .getscript, but I have no idea if I am heading in the right direction. I'm very new to all of this.

Right now, I am simply using:

$.getScript(url.php);

to call my php file.

My php file produces something like:

$(function() {
    $( "#dateStartMainChartSelect" ).datepicker({ 
        minDate: new Date(2011,03,07)),
        maxDate: +0 
    });
});

Try to change your PHP to generate a function instead of a "DomReady" script, like this:

function updatephp() {
    $("#dateStartMainChartSelect").datepicker({ 
        minDate: new Date(2011,03,07),
        maxDate: +0 
    });
}

After that you can use the callback function of getScript to start your new function:

$.getScript('ajax/test.js', function() { updatephp(); });

Tried this, but something still isn't quite working. I get "Uncaught ReferenceError: updatephp is not defined"

Try to put the function in "$(function() { }" block ?!

Ok, so I just noticed an extra closed bracket (after 07 on line 3). Once I removed that, this worked great. Thanks.
