Trigger an Event Only in the Current Div

In web development, particularly when using jQuery or vanilla JavaScript, you might come across situations where you need a specific action to take place within a specific part of the webpage. Let's take a look at a common problem: You have multiple interactive boxes each containing an "info" button, and when you click one of these buttons, you want to show a modal associated with that specific box. However, pressing any button triggers all modals at once.

This can lead to a frustrating user experience, as users may not know which information is being displayed. Fortunately, there are clear solutions that allow you to control which modal opens based on the button pressed.

The Problem Explained

You have a simple HTML structure with several div elements, each having a button and a corresponding modal. Your current code triggers all modals when any button is clicked:

As you can see, this code affects all modals, which is not the desired outcome.

The Solution

Using jQuery

To ensure that only the modal corresponding to the clicked info button is shown, you can modify your jQuery code. Here's a step-by-step breakdown:

Target the specific button clicked: Use the this keyword to reference the specific button that was clicked.

Find the associated modal: Use the .closest() method to navigate up to the parent box and then find the corresponding modal using .find().

Without jQuery

If you prefer to use vanilla JavaScript, you can achieve the same effect without relying on jQuery. Here’s how you can implement it:

Add an event listener to the parent container: This allows you to manage button clicks more effectively.

Check if the clicked element is the info button.

Toggle the corresponding modal.

Here’s the JavaScript code you would use:

Conclusion

By altering your jQuery or vanilla JavaScript code, you can ensure that only the relevant modal opens when a user clicks the "info" button in its respective box. This enhances user experience significantly by preventing confusion and maintaining context.
