How to Disable a Button using JavaScript

A common task in web development is how to programmatically disable a button using JavaScript.
In this post, we'll learn how you can use JavaScript to disable a button.
An example of when you'd want to do this is when you want to prevent a user from submitting a form until all the required fields are filled out.
A button has an internal state, similar to checkboxes and radio buttons.
This means we can manipulate the state of the button, and therefore disable it.
How to disable a button
The first thing you'll want to do is to get the button element.
If you have a class applied, you can get your button like this:
const button = document.querySelector(".button");
Now that you've gotten your button, simply set its disabled
property to true
.
const button = document.querySelector(".button");
button.disabled = true;
Conclusion
In this post, we've seen how to get a button and then disable it programmatically using JavaScript.
Hopefully, this has been helpful to you.
