jQuery | eq() with Examples

  • Last Updated : 13 Feb, 2019

jQuery is a very powerful tool which helps us to incorporate a variety of DOM traversal methods to select elements in a document randomly or in sequential order. Most of the DOM traversal methods do not modify the elements else they filter them out upon the given conditions.
The eq() method is an inbuilt method in jQuery which is used to locate the selected elements directly and returns an element with specific index.
Syntax:

$(selector).eq(index)

Parameters: Here the parameter “index” specifies the index of the element.
Can either be positive or a negative number.
NOTE:

Hey geek! The constant emerging technologies in the world of web development always keeps the excitement for this subject through the roof.

  • The index number always starts at 0, so the first number will have index 0 (not 1).
  • Using a negative number as an index starts the index count from the end of the list.

jQuery code to show the working of the eq() method:

Code #1:
Below code will select the specified elements.




<html>
  
<head>
    <title>GeeksForGeeks articles</title>
                 jquery/3.3.1/jquery.min.js"></script>
    <script type="text/javascript">
        $(document).ready(function() {
            $(".heading").eq(0).css("color", "red");
            $(".heading").eq(2).css("color", "yellow");
        });
    </script>
</head>
  
<body>
    <h1 class="heading">GeeksForGeeks</h1>
    <h2 class="heading">GeeksForGeeks</h2>
    <h3 class="heading">GeeksForGeeks</h3>
    <h4 class="heading">GeeksForGeeks</h4>
</body>
  
</html>

Output:

Code #2:
Below code will select the specified elements with negative index.




<html>
  
<head>
    <title>GeeksForGeeks articles</title>
                 libs/jquery/3.3.1/jquery.min.js"></script>
  
    <script type="text/javascript">
        $(document).ready(function() {
            $(".heading").eq(-2).addClass("style");
            $(".heading").eq(-4).addClass("style");
  
        });
    </script>
    <style>
        .style {
            color: red;
            font-family: fantasy;
            font-size: 20px;
        }
    </style>
</head>
  
<body>
    <ul>
        <li class="heading">GeeksForGeeks</li>
        <li class="heading">GeeksForGeeks</li>
        <li class="heading">GeeksForGeeks</li>
        <li class="heading">GeeksForGeeks</li>
    </ul>
</body>
  
</html>

Output:

jQuery : eq() vs get()

  • .eq() returns it as a jQuery object, meaning the DOM element is wrapped in the jQuery wrapper, which means that it accepts jQuery functions.
  • .get() returns an array of raw DOM elements.
