DataTable check in JSON returns null

[cpuinParticipant]

Hi,

I have implemented dataTable bound to PHO which returns JSON.I have a button and when click the button the table appears.
The table display records of sales.The problem is that when no sales are available the returned JSON is null and the table displays with refreshing image “loading” stacked .Is there any way when to display empty table or to not display table in null is returned value?

I’d say you’ve got a javascript/json error somewhere, which is causing an exception and leaving the “loading” image displayed – I had this when I was putting together my first DataTable.

Have you checked in the debugger (FireBug etc.) whether there are any errors?

I have no error.Just when returns null, the table stacks on “loading”
