Question

How do i get the substring $v of the class rate$v? I can’t assign $v as an id and do attr('id') because i have $v assigned as an id to other elements. How do i get $v from the class rate$v in jquery?

<?php
    foreach($v = 0; $v < 9; $v++) {
        echo "<div class='raterow'><input type='hidden' class='rate$v' value='$username' /></div>";
    }
?>

I’m assuming you want to get attributes of HTML printed with PHP, in jQuery. Correct me if I’m wrong.

Use a data- attribute. It’s an HTML5 feature, but all (most) browsers will keep any attributes they don’t understand, so it’ll work in IE6, etc.

Use jQuery.data() to get that attribute and manipulate it. PHP:

foreach($v=0; $v<9; $v++) 
{
    echo "<div class='raterow'><input type='hidden' data-vId='$v' class='rate$v' value='$username' /></div>";
}

With this jQuery:

var foo = %('.daterow input').data('vId');

You can call vId whatever you want, providing it’s prefixed with data-. Note that .data() only needs the identifier part – you can exclude data- from the parameter you pass to it.
