clear :: Form.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 }
