i had download all require js file to run jquery n jqgrid especially run the jqdemo 3.8

i'm using php 5 and mysql with xampp.

i had run sql to create database and changing configuration in file /jqdemo38/config.php with my dbhost and dbpass.

after i'm really sure that database and config.php is correct. I'm trying to running /jqdemo38/jggrid.html

And when i'm trying to run demo jqgrid about rendering all data from database, like Json Data, all data not show in jqgrid !

I show that all process to get data from database in jqdemo38 is processing in server.php.

If i direct access to server.php?q=2, the json data is display.But when rendering to jqgrid is faill or not show.

What's wrong with my jqdemo38 configuration?

Any other file javascript must we put in the folder of jqdemo3/js ? All any configuration to run the demo correctly?

Please, any one can help me?

Thanks.
