HTMLTextAreaElement: defaultValue property
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
The defaultValue
property of the HTMLTextAreaElement
interface represents the default text content of this text area. Getting and setting this value is equivalent to getting and setting textContent
on the <textarea>
.
Value
A string.
Examples
In the example below, the defaultValue
still returns the value originally written in the HTML. If a default value is set, either via HTML or the defaultValue
property, user input will update the value
but will not overwrite the defaultValue
.
js
const textareaElement = document.getElementById("comment");
console.log(textArea.defaultValue);
textArea.defaultValue = "This is the default text now!";
