Something is wrong

Except of a line (instead of tree) I didn't see any results of the demo.
Here is a message from Javascript console:

write is not defined
http://test.technion.ac.il/ajax_tree/tree.js

The same results are in IE and Firefox.

What may be the problem?

can you please let me know the php version that you are using. do confirm about availability of JSON extension.

Thanks

I have the same Prob and my PHP ver. is 4.1

thanks for using class.. you need to install php 5 version with JSON support.

I have the same problem, and my PHP version is 5.2.4.
I am sure that the JSON support is enabled.
The JSON version is 1.2.1

I solve my problem now.
I Just change the markup of "services.php".
The original markup is "<?",
after I modify that to "<?php".
The results od demo works~~
thanks for your class!!

I ve tried the referred URL but not able to execute it. Please let me know the error in detail or refer URL which is working ..

thanks

The service.php use opening <?,
and that will cause two errors.
1.write is not defined, line 1, http://localhost/ajaxtreeview/tree.js
2.invalid XML markup, line 40, http://localhost/ajaxtreeview/tree.js

after use the opening <?php,
this treeview class works fine.
