buttons-processing not working

cj1005

Hi,

My export to excel can take a minute or so with a large dataset, so I wanted to show a progress bar, I found an example from another thread, that I have adapted (see below):

qjobTable.on( 'buttons-processing', function ( e, indicator ) {     
   console.log(indicator);
   if ( indicator ) {
     showLoading();
   }
   else {
     hideLoading();
   }
} );

Then my two functions as below:

function showLoading() {
  console.log("show loading");
  document.getElementById("blackout").style.width = "5%";
}

function hideLoading() {
  console.log("hide loading");
  document.getElementById("blackout").style.width = "0%";
}

I can see in the console log, the functions are called as expected, but the bar does not appear at all.

I use these two functions throughout my web-app and the progress bar appears correctly, it is only when I try to use them with the export to Excel that nothing appears (I've tried the 'excel' and 'excelhtml5' export options, same on both).

Any suggestions appreciated?

Cheers, Chris

Its hard to say with seeing the problem occur. Please post a link to your page or a test case showing the issue so we can help debug.

Are the showLoading and hideLoading functions called? If so then you probably need to debug what happens in the functions themselves.

Do you get errors in the console?

Hi Kevin,
Thanks for your reply, I'll try debugging my functions a bit further and if I cannot solve it, I will then post my test page here.
