Methods

The following methods are provided by the HTMLInputElement interface which represents <input> elements in the DOM. Also available are those methods specified by the parent interfaces, HTMLElement, Element, Node, and EventTarget.

checkValidity()

Returns true if the element's value passes validity checks; otherwise, returns false and fires an invalid event at the element.

reportValidity()

Returns true if the element's value passes validity checks; otherwise, returns false, fires an invalid event at the element, and (if the event isn't canceled) reports the problem to the user.

select()

Selects the entire content of the <input> element, if the element's content is selectable. For elements with no selectable text content (such as a visual color picker or calendar date input), this method does nothing.

setCustomValidity()

Sets a custom message to display if the input element's value isn't valid.

setRangeText()

Sets the contents of the specified range of characters in the input element to a given string. A selectMode parameter is available to allow controlling how the existing content is affected.

setSelectionRange()

Selects the specified range of characters within a textual input element. Does nothing for inputs which aren't presented as text input fields.

stepDown()

Decrements the value of a numeric input by one, by default, or by the specified number of units.

stepUp()

Increments the value of a numeric input by one or by the specified number of units.
