HTMLInputElement: 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 HTMLInputElement interface indicates the original (or default) value of the <input> element. It reflects the element's value attribute.
Value
A string representing the default, or original, value of the <input> element.
Example
Given the following HTML:
html
<label for="planet">Which planet were you born on?</label>
<input id="planet" type="text" value="Azarath" />
The following will provide the same results, no matter what the user enters into the text input.
js
const inputElement = document.querySelector("#planet");
console.log(`Original value: ${inputElement.defaultValue}`); // "Original value: Azarath"
