    Hello Readers,

    Jquery filter is one of the jquery method. It is used to returns the elements that match the certain values from the object list.

    Syntax :

    selector.filter( selector )
    

    Parameters :

    selector

    Below is the Code Example of filter() method :

    <html>
        <head>
          <title>The jQuery Example</title>
          <script type = "text/javascript" 
             src = "http://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
    
          <script type = "text/javascript" language = "javascript">
             $(document).ready(function() {
                $("li").filter(".middle").addClass("selected");
             });
          </script>
    
          <style>
             .selected { color:red; }
          </style>
       </head>
    
       <body>
    
          <div>
             <ul>
                <li class = "top">list item 1</li>
                <li class = "top">list item 2</li>
                <li class = "middle">list item 3</li>
                <li class = "middle">list item 4</li>
                <li class = "bottom">list item 5</li>
                <li class = "bottom">list item 6</li>
             </ul>
          </div>
    
       </body>
    
    </html>
    

    Output :

    list item 1
    list item 2
    list item 3
    list item 4
    list item 5
    list item 6
    

    In the above code, we filter the class (.middle) and addClass (selected) on it.
