Usage Note 30889: Displaying the "Please Wait" message for a long-running stored process
When a user submits a long-running stored process using the SAS® Stored
Process Server, it is often helpful to issue a "Please Wait" message
to encourage the user to be patient and not press the Refresh or
Reload buttons on their Web browser. Pressing the
Refresh or Reload buttons while the stored process is running will cause the request to be
submitted a second time and the performance to become even slower.
The following example illustrates an approach for displaying the
"Please Wait" message, running the stored process, and then clearing
the "Please Wait" message at the top of the output. By default,
the "Please Wait" message will not be cleared unless you use an
approach such as that which is provided in the example.
This approach can also be used when running a request using the
SAS/IntrNet® Application Dispatcher.
/* Please Wait Example */
data _null_;
file _webout;
put '<html>';
put '<body>';
put '<div id="pleasewait">';
put '<h2>Please Wait. Your request is being processed.</h2>';
put '</div>';
do i = 1 to 10;
put " ";
end;
run;
data _null_;
x = sleep(3,1);
run;
%stpbegin;
proc print data=sashelp.class;
run;
%stpend;
/* Clear Please Wait message */
data _null_;
file _webout;
put '<script>';
put 'pleasewait.style.display="none";';
put '</script>';
put '</body></html>';
run;
