Yesterday, I suddenly found my program got crazy, after busy reinstall the system for a week or so....
I modified the program, categories.php of OSC, which is supposed to generate a form for new products.
My modification made the filling easier so that it can automatically fetch products information from a library
as soon as I provided the ISBN. The automatically fetch data is of course triggered by a javascript event onchange,
and the javascript called AJAX to get the data.
It was all right. But now, before I even entered an ISBN, the form is filled, with some fixed data. I mean, I just start the program and tell it I am going to fill the form. It is suppose to give me an empty form. The event has not even be triggered.
The pre-filled data is indeed one of my previously inserted product. I even tried to remove that product,
the the filled form is still the same.
I remember I made some modifications to the program, and I have removed those modifications, but no use.
I just don't know where to start debug.
