I've included a "Cancel" button on a form that posts to an ASP page for processing, and which uses JavaScript for form validation. The "Cancel" button uses the following code:

<input type = button onclick='javascript: history.back(1)' value=&quot;cancel&quot;>

When I click on the button, however, nothing happens. I've used several variations on the code above, and can't get it to work. Does anyone have any ideas?

Thanks!

Try this:
<input type=button onclick='javascript:history.back(-1)' value=&quot;cancel&quot;> I have not failed; I merely found 100,000 different ways of not succeding...

hi Marmalade,

back() does not take any arguments - this should work:

<input type = button onclick='history.back();' value=&quot;cancel&quot;>

this will also work:

<input type = button onclick='history.go(-1);' value=&quot;cancel&quot;>
======================================

if (!succeed) try();

history.back() doesn't take any arguments. history.go() uses positive or negative numbers for arguments.

doesn't history.go(-1) work more widly as well?
I think I remember this coming up once. may be wrong though [bomb]
I may not get it the 1st or 2nd time,
but how sweet that 15th time can be.

Thanks, everyone - the button works beautifully now! I have noticed something strange, though; my JavaScript routines never execute in my development environment (I run my test pages on a PC workstation running IIS). They work just fine in my production environment, however. Anyone know why that might be the case? I thought my workstation IIS would automatically have a JavaScript engine, but could I be wrong?

Thanks again,

M

Marmalade,

javascript is executed client-side in the browser. it does not matter if you are using a webserver such as IIS. can you post the code for the routines have you written that are not working?

check this in your development environment:

<html><body onload=&quot;alert('hello')&quot;></body></html>

======================================

if (!succeed) try();

Thanks, Jeff; I should have realized that my webserver wouldn't have anything to do with JavaScript execution!

I saved the alert(hello) snippet to a standard HTML file, and it worked perfectly in my development environment. For some reason, however, the JavaScript embedded in my ASP pages *won't* run on development. Here's an example of a function that I use for form validation on a login page:

Code: 
<script language=javascript type=&quot;text/javascript&quot;>

<!-- Hide script from older browsers

// This script alerts the user if s/he forgets to enter a username or password

function validForm(passForm) 
	{
	if (passForm.Username.value == &quot;&quot;)
		{
		alert(&quot;Please enter a username&quot;)
		passForm.Username.focus()
		return false
		}
	if 	(passForm.Password.value == &quot;&quot;)
		{
		alert(&quot;Please enter a password&quot;)
		passForm.Password.focus()
		return false
		}
	return true
	}
	// End hiding script -->

The FORM tag looks like this (please disregard the VBScript, which is included for ASP purposes - unless you think that's part of the problem!):

Code: 
<FORM onSubmit=&quot;return validForm(this)&quot; ACTION=&quot;CheckLogin.asp
<% If Request(&quot;SecondTry&quot;)=&quot;True&quot; Then  Response.Write &quot;?SecondTry=True&quot; End If %>&quot; METHOD=&quot;POST&quot;>

Aside from this material, the page includes a link to a style sheet, and the form elements themselves (which also contain some VBScript for ASP purposes) - but that's it.
