How to Get the src Value of the Nearest Image Using jQuery

Have you ever encountered a situation where you need to retrieve the src attribute from an image related to a button click? This is a common challenge for web developers using jQuery. In this guide, we will explore how to achieve this seamlessly, using a simple HTML structure.

Understanding the Problem

Imagine you have a set of product images and corresponding buttons. When a button is clicked, you want to capture the source URL of the associated image. Here's a simplified version of the HTML structure we will be working with:

In the example above, the button with class btn-add-cart sits next to an image. When this button is clicked, we want to retrieve the URL of the image to potentially use for further interactions or display.

The Solution

To accomplish the above, we can utilize jQuery's powerful selector functionalities. The key here is to effectively traverse the DOM from the button to the nearest image element.

Step-by-Step Implementation

Set Up jQuery: Ensure that you include jQuery in your HTML file. You can do this by adding the following <script> tag to the head of your HTML document:

Event Handling: We will use jQuery's .on() method to listen for click events on the buttons:

Finding the Image Source: Inside the event handler, use the .closest() method to navigate up to the nearest <figure> element, and then use .find() to target the <img> element:

Putting it all together, your complete jQuery solution will look like this:

Explanation of the Code

.on('click', 'button', function() {...}): This listens for clicks specifically on buttons within any .product-default div.

$(this).closest('figure'): This finds the closest parent <figure> element relative to the clicked button.

.find('img'): This searches for the <img> tag within the found <figure>.

.attr('src'): Finally, this retrieves the value of the src attribute from the found <img> tag.

Conclusion

By following the steps outlined above, you can easily retrieve the src attribute of an image when its corresponding button is clicked. This method is versatile and can be adapted to different layouts and structures as needed.
