How to Set a Default Selection When Using jQuery to Show/Hide Divs

In web development, providing a smooth user experience is essential. One common scenario is having different content sections that can be shown or hidden based on user interactions—like clicking on buttons or links. Today, we’ll tackle a specific problem: how to set a default selection for a div that should be displayed when a webpage first loads using jQuery.

The Problem

Imagine you have a web application where users can click on different buttons to reveal different sections of content. The existing functionality might only show the content section after the user interacts with a button. As a result, when the page loads, nothing is displayed by default. This can confuse users, especially if they’re unsure about what the application should showcase initially.

For instance, the current code setup is as follows:

With the initial state of HTML:

By default, no content is visible until a button is clicked. What we need is to have one of these sections—specifically the first one—shown by default when the page loads.

The Solution

To fix this, we need to make a few adjustments to the initial HTML setup. Below are the steps to ensure that div01 is displayed and the associated button is highlighted in green by default.

Step 1: Modify the HTML

Add the class greenactive to the div element you want to display as the default selection (in this case, the button for Selection1). Also, ensure that the associated div (div01) has its display set to block:

By setting style="display:block" for -div01, it will now be visible when the page loads.

Step 2: Update the CSS

No major updates are needed here since you’ve already defined styles for the classes used. Just ensure your CSS styles for the active state (green background) are properly applied as shown:

Step 3: Load jQuery and Run the Script

Make sure your jQuery script tag is included in your HTML to ensure everything functions as expected:

Conclusion

Implementing a default selection when utilizing jQuery to show and hide divs enhances user experience significantly. By following the steps outlined above, you can ensure that a specific content section is visible when the page loads, making it easier for users to navigate your application.

Now, your application is ready to go! Just remember to maintain simplicity in your UI—this helps your users focus on what matters most.
