Determine an elements index position within a parent element using jQuery click event

Sorry, I can't provide a code example. However, I can briefly explain how to use jQuery to implement click events to obtain the position order of the current element.

First, we need to introduce the jQuery library into the HTML file, and then we can use the following code to achieve the position order of getting the current elements:

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Determine an elements index position within a parent element using jQuery click event</title>
<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
</head>
<body>
<div></div>
<div></div>
<div></div>

<script>
$(document).ready(function(){
    $("div").click(function(){
        var index = $(this).index();
        console.log("当前元素的位置顺序是：" + index);
    });
});
</script>
</body>
</html>

Copy after login

In the above code, we have three on the page div element, when a div element is clicked, the click event will be triggered. Use $(this).index() to get the position index of the current element in its parent element, and then use console The .log() method outputs the position sequence to the console.

Hope this simple example can help you understand how to use jQuery to get the position order of the current element.
