[Javascript] RES: Maximun length of an id

Can't you create the elements on the fly? I use xmlhttprequest to load a php
page and document.write the result. This way you can hide most part of the
code, including html stuff. If you need a sample, call me back.

Assunto: Re: [Javascript] Maximun length of an id

The reason for encrypting is because the id would "mean" something to  
the server, and someone could determine what it means to the server  
and change it to get the server to do something the page never wanted  
it to do.

I think I can illustrate by showing an example without an encrypted id.

<div class="editable" id="recordid-01234">
  This is the data from my database. It is record number 01234
</div>

If I take this example and then write some snazzy Javascript to post  
new data to the server, then I have just exposed my database. All  
someone would have to do is determine how my post is working and  
change recordid-01234 to recordid-01231 or something like that.

Does that make sense?
