HTMLInputElement: max 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 max property of the HTMLInputElement interface reflects the <input> element's max attribute, which generally defines the maximum valid value for a numeric or date-time input. If the attribute is not explicitly set, the max property is an empty string.

Value

A string representing the element's max value or an empty string if no max is explicitly set.

Example

js
const inputElement = document.querySelector("#time");
console.log(inputElement.max); // the current value of the max attribute
inputElement.max = "18:00:00"; // sets the max value to 6pm
