How To Check Uncheck Radio Button On Click

Radio buttons are a common feature in web forms, allowing users to select a single option from a list. However, sometimes you might need to uncheck a radio button after it has been selected. In this article, we'll discuss how you can check and uncheck a radio button with just a simple click using JavaScript.

To start off, let's understand how radio buttons work. Radio buttons are grouped under the same name attribute to ensure that only one option can be selected at a time. This means that when one radio button is selected, others in the same group automatically get deselected. But what if you want to allow users to unselect a radio button by clicking on it again?

To achieve this functionality, we can use JavaScript to detect when a radio button is clicked and toggle its checked state. Below is a simple script that demonstrates this process:

Option 1


   const radioButton = document.getElementById("radioButton");

   radioButton.addEventListener("click", function() {
      if (this.checked) {
         this.checked = false;
      } else {
         this.checked = true;
      }
   });

In the code snippet above, we first select the radio button element using its `id`. We then add an event listener to listen for the `click` event on the radio button. When the radio button is clicked, the event listener checks whether the button is currently checked. If it is checked, the script unchecks it by setting `checked` to `false`. If it is not checked, the script checks it by setting `checked` to `true`.

This simple script allows users to toggle the state of the radio button by clicking on it repeatedly. You can customize this script further by adding additional logic or styling to suit your specific requirements. For example, you can trigger other actions based on whether the radio button is checked or unchecked.

It's important to note that manipulating the checked state of a radio button dynamically can alter the expected behavior of radio button groups in your form. Make sure to test your implementation thoroughly to ensure it works as intended and doesn't confuse users.

In conclusion, with a basic understanding of JavaScript and event handling, you can easily implement the functionality to check and uncheck a radio button with a simple click. Experiment with the provided script and tailor it to your needs to enhance user experience on your web forms.
