JavaScript 1.0; enhanced in JavaScript 1.1
<input type="reset" onclick="handler" ... > reset.onclick
The onclick property of a Reset object refers to an event handler function that is invoked when the user clicks on the
Reset button. See the HTMLElement.onclick reference page for complete details. Note, however, that Reset.onclick has been supported since JavaScript 1.0, unlike the generalized HTMLElement.onclick handler.
The
Reset button has the special function of resetting all form elements to their default value. The onclick event handler may add any additional functionality to the
Reset button. In JavaScript 1.1, the onclick handler may return false to prevent the Reset object from resetting the form. (For example, the onclick handler could use confirm( ) to ask the user to confirm the reset and return false if it was not confirmed.)
