Reduce the set of matched elements to the one at the specified index.

.eq(index)🡢 jQuery

index IntegerAn integer indicating the 0-based position of the element.

.eq(indexFromEnd)🡢 jQuery

indexFromEnd IntegerAn integer indicating the position of the element, counting backwards from the last element in the set.

Given a jQuery object that represents a set of DOM elements, the .eq() method constructs a new jQuery object from one element within that set. The supplied index identifies the position of this element in the set.

Consider a page with a simple list on it:

  <li>list item 1</li>
  <li>list item 2</li>
  <li>list item 3</li>
  <li>list item 4</li>
  <li>list item 5</li>

We can apply this method to the set of list items:

$("li").eq(2).css("background-color", "red");

The result of this call is a red background for item 3. Note that the supplied index is zero-based, and refers to the position of the element within the jQuery object, not within the DOM tree.

Providing a negative number indicates a position starting from the end of the set, rather than the beginning. For example:

$("li").eq(-2).css("background-color", "red");

This time list item 4 is turned red, since it is two from the end of the set.

If an element cannot be found at the specified zero-based index, the method constructs a new jQuery object with an empty set and a length property of 0.

$("li").eq(5).css("background-color", "red");

Here, none of the list items is turned red, since .eq( 5 ) indicates the sixth of five list items.

Turn the div with index 2 blue by adding an appropriate class.

div {
  width: 60px;
  height: 60px;
  margin: 10px;
  float: left;
  border: 2px solid blue;
.blue {
  background: blue;
