onreset Attributeonreset AttributeThe onreset attribute may be used on
a form element
to specify script to be executed when a Reset button for the form
is activated - or when, for example, the JavaScript method
Form.reset() is called for that form.
If the onreset script returns
false then the form will not be reset (in script-enabled user agents).
See also the onsubmit and
onclick attributes.
If you use this attribute (or any attributes of Type Script) the MIME type of the scripting language used should always be provided in a Content-Script-Type HTTP header.
It is good practice not to use these attributes, however,
and instead to include external scripts (via
script elements)
which add any handlers unobtrusively. This makes code more self-contained and
also the XHTML is easier to maintain if it doesn't contain any events attributes.
