Executing javascript code as a GIF file?

Execute javascript code as a GIF file

[sumitshah4u]

Hi,

I saw this interesting link at [hiermenuscentral.com...] . It is a DHTML drop down menu ( horizontal as well as vertical ). When it see the code through "view source" and try to find where the dhtml javascript code is coming from , i am come across 2 lines :

<p><img name="hm_i_main1" id="hm_i_main1" src="/art/t.gif" width="1" height="23" alt="Menu Placer #1" /></p>

<p><img id="hm_i_main2" name="hm_i_main2" src="/art/t.gif" width="160" height="150" alt="Menu Placer #2" align="left" />

I think this is SMART. The gif files above are getting the javsscript code from some where and executing the drop down menus. Thus, they are securing the client side code. This can be a major resource for coders who want to hide their code.

Can any body explain the phenomeneon?

Rgds,

Sumit.

I think they're just images.

There is a <script> tag right at the bottom of the page code.
This script writes more to the document, including further <script> tags.

If you want to know what the 'actual' source code of the page is when it's up & running, paste this into your browser's address bar (IE only):

-- all one line --

javascript:z1=document.documentElement;z2=window.open("","","width=400,height=400,scrollbars=1,resizable=1;");z2.document.open("text/plain");z2.document.write(z1.outerHTML);void(0);
