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

To make it optionally case insensitive: http://bugs.jquery.com/ticket/278

$.extend($.expr[':'], {
  'containsi': function(elem, i, match, array)
  {
    return (elem.textContent || elem.innerText || '').toLowerCase()
    .indexOf((match[3] || "").toLowerCase()) >= 0;
  }
});

then use :containsi instead of :contains
