class method Form.Element.clear
Form.Element.clear(element) → Element
Clears the contents of a text input. Returns the element.
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
}
This method can be called either as an instance method or as a generic method. If calling as a generic, pass the instance in as the first argument.
