clear :: Form.Element

clear(element) -> HTMLElement Clears the contents of a text input.

Example

This code sets up a text field in a way that it clears its contents the first time it receives focus:

$('some_field').onfocus = function() {

// if already cleared, do nothing

if (this._cleared) return

// when this code is executed, "this" keyword will in fact be the field itself

this.clear()

this._cleared = true

}
