Is there a case insensitive jQuery :contains selector?

Question

Is there a case insensitive version of the :contains jQuery selector or should I do the work manually by looping over all elements and comparing their .text() to my string?<

Answer 1

A faster version using regular expressions.

$.expr[':'].icontains = function(el, i, m) { // checks for substring (case insensitive)
    var search = m[3];
    if (!search) return false;

    var pattern = new RegExp(search, 'i');
    return pattern.test($(el).text());
};
