Hide/Show Div When Radio Checked/Unchecked via a Button

In web development, interactivity can significantly enhance the user experience. A common scenario involves showing or hiding content based on user input, such as selecting options with radio buttons. If you've encountered an issue with toggling visibility of a div based on radio button selections, you're in the right place! Today, we'll break down how to resolve the problem where a div fails to display despite the corresponding radio button being checked via a button click.

The Problem at Hand

You currently have a situation where you want a specific div, termed NYHA, to appear when a user selects “Oui” (yes) from the “Dyspnée” section by clicking buttons that change the radio selection. However, despite clicking the button that should check the “Oui” option, the NYHA div does not appear as expected. Let's dive into how we can troubleshoot and resolve this issue effectively.

Understanding the Existing HTML and JavaScript

First, let’s briefly examine the relevant parts of your HTML and JavaScript code:

In the above code, the NYHAshow() function is called when the radio button is changed. However, if you are checking the radio button programmatically via a function (like clicking the “PulmOui” button), the change event does not fire, leading to the NYHA div not being displayed.

The Current JavaScript Functions

Here are the relevant functions you currently have:

The PulmOui() function correctly checks the necessary radio buttons, but it omits the call to the NYHAshow() function.

The Solution

To solve this problem, we need to ensure that the visibility toggle function is called whenever the buttons are used to change the state of the radio buttons. Here’s how you can adjust your existing PulmOui() function:

Solution Implementation

By adding the line NYHAshow(); within the PulmOui() function, we explicitly call the function that reveals the NYHA div when the user checks "Oui" using the button.

Conclusion

By implementing the above modification, you are now able to successfully toggle the visibility of the NYHA div whenever the corresponding "Oui" button is pressed. This solution ensures that no matter how the radio button is selected—whether by clicking the explicit radio option or using the button to change it—the requisite div will display as intended.

Remember, interactive elements in web applications should always consider how user actions—like button clicks or radio selections—affect the user interface. If you run into similar challenges in the future, this approach can be used as a reference for handling dynamic UI changes!

Happy coding!
