:eq()    ** DEPRECATED ** JQ Home  <<  Selectors  <<  :eq()

• <<    :animated Selector

Equals index selector.

Shorthand version $(':eq(index)')

Description

The :eq() selector, selects the element at index n within the matched set.

• Like all the positional selectors :eq() uses a zero-based index to select from previously filtered elements.
• Being a jQuery extension the :eq() pseudo selector is not part of any current CSS specification. Therefore :eq() cannot take advantage of the performance boost provided by the native DOM querySelectorAll() method.
• The same results can be achieved with better performance using the eq() method with a valid CSS selector, for example $("cssSelector").eq(index).

This method was deprecated in jQuery 3.4.

N/A.

:eq() Example Selectors  <<  Top

Selects the element at index n within the matched set.

In the example below when we press the left button we apply an orange background to the 2nd table row (notice that index is 1).

When we press the left button we apply an teal background to the 2nd table row from the end (notice that index is -2).

$(function(){
  $('#btn11').on('click', function() {
    $('.testtable tr:eq(1)').css('backgroundColor', 'orange');
  });
  $('#btn11b').on('click', function() {
    $('.testtable tr:eq(-2)').css('backgroundColor', 'teal');
  });
});
