How to Store a Clicked Image's Source in a JavaScript Variable

Handling user interactions like clicks is an essential part of web development. One common task for developers is to store the src of a clicked image into a JavaScript variable. This task can refine user interfaces or trigger particular actions based on the image selected. In this guide, we'll explore this concept with an easy-to-follow approach.

Understanding the Basics

To effectively achieve this, we need to have a clear understanding of two main components: the click event and the attribute manipulation in JavaScript.

Typically, images on a webpage are represented with <img> tags, which have an src attribute pointing to the image source. With JavaScript, you can capture the click event on these images and then access the src attribute to store it in a variable.

Implementing the Solution

Let's walk through a simple implementation.

HTML Setup

First, ensure your HTML includes at least one image element you plan to interact with:

JavaScript Code

Now, we'll write the JavaScript to capture the click event and store the src in a variable.

Explanation

Handle the Click Event: A function storeImageSrc() is created to handle the click event. This function receives the event object that contains valuable information about the click action.

Event Listener: We use addEventListener() to bind the click event to our function.

Conclusion

By following these straightforward steps, you can efficiently store the src of a clicked image in a JavaScript variable. This functionality opens doors to dynamic behavior on websites, making them more interactive and user-friendly.

Exploring this further, you could extend this capability to work with multiple images, trigger other UI changes, or even build a gallery selection system. The possibilities are endless, only limited by your creativity.
