Synopsis

<form ... onreset="handler" ... >
form.onreset

Description

The onreset property of a Form object specifies an
event handler function that is invoked when the user clicks on a

Reset button in the form or when
Form.reset( ) is called.

The initial value of this property is a function that contains the
semicolon-separated JavaScript statements specified by the
onreset attribute of the HTML
<form> tag. When an event handler function
is defined by an HTML attribute, it is executed in the scope of
element rather than the scope of the
containing window.

In the Netscape 4 event model, the onreset handler
function is passed an Event object as an argument. In the IE event
model, no argument is passed, but the applicable Event object is
available as the event property of the Window
object that contains the element.

If the onreset handler returns
false, the elements of the form are not reset.

Example

You could use the following event handler to ask the user to confirm
that they really want to reset the form:

<form ...
onreset="return confirm('Really erase all entered data?')"
>
