Re: [Dynapi-Help] dynapi.onUnload question

[Raymond I. <xw...@ya...>]

Problem: onUnload can't return false to stop the
location change like onSubmit can do.

Workaround: Check if the page should be unloaded in
onClick in all links and in onSubmit in all forms.
It's not elegant, but it works.

Code Example: We have a function check(), returning
true if the page should be unloaded, false otherwise.

A link:

<a href="p.html" onClick="return( check() );">

A form:

<form action="p.pl" onSubmit="return( check() );">
