Object exists?

@cmkohrmannDec 13.2006

I have two buttons on my page. One is exit and the other is cancel and only one is visible at a time. I would like to know if somehow in Javascript can I tell which object exist and perform certain VB code displaying a confirmation message when clicking on cancel when the cancel button exists and just closing the page when the exit button exists.

thanks,

Cheryl

JavaScript

@so_is_thisDec 13.2006 — #Are you talking about this? ...when you say VB code?

<i>
 </i>&lt;script type="text/vbscript"&gt;
 &lt;!--'
 Dim obj, id
 id = "MyButton"
 Set obj = Document.getElementById(id)
 If obj Is Nothing Then
 MsgBox id &amp; " does not exist."
 Else
 MsgBox id &amp; " does exist."
 End If
 '--&gt;
 &lt;/script&gt;

@cmkohrmannauthorDec 13.2006 — #Ok, I'm new to JavaScript but my boss thought that I should be able to do something like this....

create the function to check

if the btnCancel exists or is enabled then

MsgBox id & " Save before cancel?"

elseif btnExit exists or is enabled then

close the window.

Are you saying that I can identify by the elementID to see what button was pressed?

Thanks for your fast response.
