Question

what it does:

<p class="foo"></p>
$('p').addClass('bar');

output:

<p class="foo bar"></p>

what i need:

<p class="bar foo"></p>

So is it possible to add a class to an element to the first position?

edit (context): theres a split function on the last class right now. if another class is added its appended to the second split array as well.

Answer 1

function prependClass(sel, strClass) {
    var $el = jQuery(sel);

    /* prepend class */
    var classes = $el.attr('class');
    classes = strClass +' ' +classes;
    $el.attr('class', classes);
}
