Need help to make jQuery .find case insensitive

Question

Trying to make this jQuery filter that uses .find case-insensitive.

For example, when the search = \"cat\" (no quotes) it will find \"cat\" but not \"Cat\" or \"CAT\". S

Answer 1

Convert both strings to lowercase, and then do the search:

search = $(this).val().toLowerCase();

$li.text().toLowerCase().search(search);

Answer 2

you want to make case insensitive searches. try using regex search(/string/i)

$("#filter").live("keyup", function (ev) {
    var $filter = $(this),
        keyCode = ev.keyCode || ev.which,
        search;

    if (keyCode === 27) { //ESC
      $filter.val("");
    }

    search = $(this).val() ;
    // added
    var search_regex = new RegExp(search, 'i');
    $("#results").find("li").each(function () {
      var $li = $(this);
      if (search === "") {
        $li.show();
      } else {
        if (_.include(service_names, search)) {
          $li.toggle($li.hasClass("items-" + search));
        } else {
          // changed here
          if (search_regex.test($li.text())) {
            $li.show();
          } else {
            $li.hide();
          }
        }
      }
    });
 });
