How to Change Text of Button using JavaScript

JavaScript is great for creating dynamic web page, thanks to its ability to programmatically alter the DOM.

One of the most common ways to alter the DOM is by changing the text of a button element.

In this post, we'll learn how to change the text of a button element using JavaScript.

Change the text of a button element

To learn how to do this, we'll use the following HTML:

HTML
<input type="button" value="Click Me!" class="button" />

The button element has a value attribute, in this case, Click Me!.

To change the text, first we must get a reference to the button element.

We can do this by using the document.querySelector() method.

JAVASCRIPT
const button = document.querySelector(".button");

Once we have the button, we can alter the text of the button by setting a new value for the value attribute.

Here's how to do that:

JAVASCRIPT
const button = document.querySelector(".button");

button.value = "This is a new text!";

After that, the DOM looks like this:

HTML
<input type="button" value="This is a new text!" class="button" />

While this changes the value, it does not change the text that is displayed on the button. To change the text, we must use the innerText property.

JAVASCRIPT
const button = document.querySelector(".button");

button.innerText = "This is a new text!";

After this code is run, the user will now see a button with the text This is a new text!.

Conclusion

In this post, we learned how we can use JavaScript, value and innerText to change the text of a button element.

This is useful when creating dynamic web experiences that require a changing button programmatically.
