Get The Clicked Object That Triggered Jquery Blur Event Duplicate

So you're working on a project that involves handling jQuery blur events and need to figure out how to get the exact object that triggered the event? No worries, we've got you covered! In this guide, we'll walk you through the steps to get the clicked object that triggered a jQuery blur event and avoid getting duplicates.

First things first, let's understand what the jQuery blur event is all about. The blur event occurs when an element loses focus. This could be triggered by clicking outside of an input field, pressing the "Tab" key, or programmatically removing focus from the element. Now, let's dive into how you can retrieve the object that caused the blur event and prevent any duplication.

To get the clicked object that triggered the blur event, you can use the `relatedTarget` property of the event object. This property gives you access to the element that is gaining focus, which helps you identify the object that triggered the blur event effectively.

Here's a simple example to demonstrate how you can use `relatedTarget` to retrieve the clicked object:

$("input").on("blur", function(event) {
    let clickedElement = $(event.relatedTarget);
    console.log(clickedElement);
});

In this code snippet, we're attaching a blur event listener to all input elements on the page. When an input field loses focus, the callback function will be executed, and `event.relatedTarget` will give you the clicked object, allowing you to perform any necessary actions based on that object.

Now, to prevent the duplication of blur event triggers, you can keep track of the previously focused element and compare it with the newly focused element. By doing so, you can ensure that you're only reacting to genuine blur events and not handling duplicates.

Here's an enhanced version of the code snippet that prevents duplicate blur event triggers:

let previousElement = null;

$("input").on("blur", function(event) {
    let clickedElement = $(event.relatedTarget);

    if (clickedElement[0] !== previousElement) {
        console.log(clickedElement);
        // Your logic for handling the click event goes here

        previousElement = clickedElement[0];
    }
});

In this updated code, we introduced a `previousElement` variable to store the previously focused element. By comparing the `clickedElement` with `previousElement`, we can ensure that we're not processing duplicate blur events.

By following these steps and understanding how to leverage the `relatedTarget` property, you can effectively retrieve the object that triggered a jQuery blur event and prevent any duplicates in your application. Happy coding!
