Last Updated : 20 Jun, 2024

Below are the methods to get the class of an element that has fired an event:

Method 1: Using JavaScript

In this approach, we are using the JavaScript onClick() event. The this.getAttribute('class') method enables the retrieval of the class of the element that triggered the event. When a user interacts with any element, the click event is triggered, allowing us to capture the class of the respective element. To obtain the class name of the specific element, utilize the syntax `onClick = function(this.getAttribute('class'))`.

HTML

<!DOCTYPE html> <html>  <head>     <title>         Getting the class of the element that         fired an event using JavaScript.     </title>     <style>         #div {             background: green;             height: 100px;             width: 200px;             margin: 0 auto;             color: white;         }          #gfg {             color: green;             font-size: 20px;             font-weight: bold;         }     </style> </head>  <body style="text-align: center;">     <h1 style="color: green;">         GeeksforGeeks     </h1>     <p>         Click on the DIV box or button to get Class of         the element that fired click event.     </p>     <div class="DIV" id="div" onClick="GFG_click(this.getAttribute('class'));">         This is Div box.     </div>     <br />     <button class="button" id="button"         onClick="GFG_click(this.getAttribute('class'));">         Button     </button>     <p id="gfg"></p>     <script>         let el_down = document.getElementById("gfg");         function GFG_click(className) {             // This function is called, when the              // click event occurs on any element.             // get the classname of element.             el_down.innerHTML = "Class = " + className;         }     </script> </body>  </html>

Using JQuery

In this approach, the onClick() event is utilized, triggering when a user interacts with an element. The $(this).attr('class') method retrieves the class of the element on which the event occurred, enabling the identification of the triggering element's class. To retrieve the class of the element that fired the event, the syntax onClick = function($(this).attr('class')) is used.
