JQuery escapeSelector() Method

Last Updated : 08 Jul, 2020

The escapeSelector() method in jQuery is used to escape CSS selectors which have special significant character or string. It can select the element of id(‘#ID1’, ‘#ID2’) and elements of class(‘.class1’, ‘.class2’). Let us understand it with the help of few examples.

Syntax:

jQuery.escapeSelector( selector )

Parameters: This method accepts single parameter selector that holds a string which contains a selector expression to escape (example ‘#ID1’ etc).

Example 1: This example selects elements of class = ‘.list’.

<html> 
  
<head> 
    <title> 
        jQuery escapeSelector() method 
    </title> 
  
    <script src= 
"https://code.jquery.com/jquery-3.5.0.js"> 
    </script> 
  
    <style> 
        li { 
            width: 150px; 
            margin: 0 auto; 
        } 
  
        .highlight { 
            background-color: green; 
        } 
    </style> 
</head> 
  
<body style="text-align:center;"> 
  
    <h1 style="color:green;"> 
        GeeksForGeeks 
    </h1> 
  
    <p id="GFG_UP"></p> 
  
    <ul> 
        <li class=".list">GFG_0</li> 
        <li class=".list">GFG_1</li> 
        <li class="list">GFG_2</li> 
        <li class="list">GFG_3</li> 
        <li class=".list">GFG_4</li> 
    </ul> 
    <br> 
  
    <button onclick="Geeks()"> 
        Click here 
    </button> 
      
    <p id="GFG_DOWN"></p> 
  
    <script> 
        var elUp = document.getElementById("GFG_UP"); 
        var elDown = document.getElementById("GFG_DOWN"); 
  
        elUp.innerHTML =  
            "JQuery | escapeSelector() method"; 
  
        function Geeks() { 
            $("ul").find("." + $.escapeSelector( 
                        ".list")).addClass("highlight"); 
  
            elDown.innerHTML = "The list elements of class" 
                    + " '.list' are highlighted not the " 
                    + "elements of class 'list'"; 
        }  
    </script> 
</body> 
  
</html> 

Output:

Example 2: This example selects elements of ID = ‘#list’.
