I have 3 Bootstrap tabs, each with a table showing query results. When the search button is clicked, or a tab is changed, an ajax call is triggered that has a beforeSend
function which shows a Bootstrap progress bar. The progress bar always shows the first time I load the page, but then is only intermittent after that. I can't seem to figure out when it shows and when it doesn't. The searches can take 5 or 6 seconds, so it's really necessary to have something for the user to know the search is running.
I saw some threads about async:false causing issues in chrome, but I don't have that set and the issue also shows up in Firefox.
I also saw a thread about having the ajax call wrapped in a document.ready, but this code is in a separate .js file?
OK, the function is long. I'm putting the whole thing in case there's some conflict. I tried commenting out the multiple ajax calls in the success function and just running the one with the beforeSend function but the issue still showed up.
Let me know if you have any ideas to troubleshoot or a potential work around...Thank you!

from Ajax beforeSend sometimes doesn't fire to show bootstrap progress bar
