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

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
