Improve Inefficient Jquery Selector

In IntelliJ, if I use a jQuery selector such as: $('#roleField option').each(function() { // impl omitted }); The selector is highlighted with a suggestion that I should spli

Solution 1:

From the jquery documentation this method will not go through the Sizzle sector engine:

$('#roleField option').each(function() {
    // No Sizzle
}); 

Where this one will:

$('#roleField').find('option')  // Sizzle!

Look at the ID base selectors section here. Hence the second method will be faster than the first.

Solution 2:

Try to use .find() here:

$('#roleField').find('option').each(function() {
    // impl omitted
});

Your warning seem like related to efficiency of the selector.
