Fixing jQuery: How to Ensure Your Overlay Displays Correctly on User Interaction

Creating interactive features in a web application can sometimes be tricky, especially when using jQuery to display overlays. In this guide, we will address a common issue that developers face: the overlay is visible on page load when it should only appear on user interaction, such as clicking a search icon.

The Problem

Picture this scenario: You are implementing an overlay on your web page that is supposed to be displayed when a user clicks the search icon. However, upon refreshing the page, you notice that the overlay is already visible, which is not the expected behavior. The overlay should only appear after the user interaction.

Use Case

Trigger: When a user clicks the search icon on the page.

Action: The overlay should be displayed.

Close: The user should be able to click a close button to remove the overlay.

Context

The current setup utilizes a development environment with Node.js and Webpack, and you've structured your JavaScript code as follows:

scripts.js: Imports the main CSS file and instantiates modules.

Search.js: Contains the overlay code using jQuery and exports the default Search.

The Solution

The issue with the overlay being displayed prematurely lies in the HTML markup itself.

HTML Markup Correction

Currently, your overlay HTML is structured like this:

The presence of the s-overlay--active class means that the overlay will be visible as soon as the page loads. To fix this, you need to remove this class from the initial HTML markup.

Updated HTML

Change it to:

JavaScript Logic

With the adjusted HTML, your JavaScript can work as intended. Let's briefly revisit the Search.js code to ensure clarity on how events are handled:

Key Code Elements Explained

Event Listeners: The events() function binds click handlers to your buttons.

Overlay Methods:

openOverlay function adds the s-overlay--active class to display the overlay.

closeOverlay function removes this class to hide the overlay.

CSS Considerations

Ensure your CSS handles the visibility and animation correctly. Here’s a brief note on the relevant styles:

Recap

Remove the s-overlay--active class from the HTML markup to prevent the overlay from showing on page load.

Verify that your jQuery code properly opens and closes the overlay when the respective buttons are clicked.

With these changes, your overlay should function as desired, providing a smooth user experience without any unwanted visibility issues.
