You really can't rely on any javascript modified page to contain the
correct settings when you use the back button. This is because the
Browser will often use a cached version of the page and may refresh the
page from the cache when "back" is executed.
This is generally why server-side validation is usually done by a
self-submitting form - so that the "state" of the form can be carried
across and reinitialised correctly if there is an error.
The other option would be to use client-side validation and then negate
the need for a "back" link. However, you may still need server-side
validation in case a form is submitted in another way other than through
your client side form.

[cfaussie] OT: Javascript enabling and disabling?
Hi guys,
sorry for the OT, but I'm stumped with this JS problem and I know some of
you are gurus with this stuff...
I've got a form with a checkbox and some text boxes. Initially the text
boxes are disabled, using the code:
<input name="full_unc_path_to_server" type="text" value="" size="100"
maxlength="255" disabled>
...and, when the checkbox is ticked, it has an onclick action that runs
some javascript 'toggle' code to enable the textboxes.
This all works absolutely fine. The problem is that, when the user submits
the form, and I do some server-side validation of the inputs and find a
problem, the user gets an error, and is told to click 'back' (and is
presented with a <a href="javascript:history.back(1)"> link) to correct
the error.
At this point, the form is still displaying the info that they have just
entered previous to submitting the form, which is what I want. The problem
is that if the checkbox mentioned above was checked before submitting the
form, it is checked now; yet the text boxes are disabled. And if you
uncheck the checkbox, the text boxes become active, as they're getting the
toggle action from the javascript code :)
I tried adding the below code to a function called with the body onLoad
action, but that doesn't seem to work.
function StartPage ()
{
if (document.form1.copied_to_server.checked == true)
{
ToggleUNC
}
}
Any ideas guys?
Cheers,
John :)
