Function Query whether the frontend is currently waiting for the server's response
Example <<button
 
 onclick="if (!S10Busy()) show_details(); return false;" >
    Details
</button>
Parameters
Nr Description
Description  The function returns "true" if a response from the ABAP server application is currently being waited for, otherwise "false".

The explicit query with S10Busy() is only necessary if you call your own functions realized in JavaScript that should not be started by the user during the waiting state.

The S10 standard functions S10Apply() and S10Enter() f already perform the S10Busy query automatically.
