Long running page issue

addis_a · January 22, 2015, 9:30am

Hi,

I know it is possible to display spinners for long running Ajax calls.
Can
we display any progress-bar/ spinner over the client side for the long
running non-ajax request?

Please suggest some way to achieve that.

Regards,
Seeni Rafiyullah Khan A,

You can do a fake progress bar in JavaScript, but unless your server has
some way to calculate the remainder of the request, and you have (most
likely need to recompile Apache) installed some sort of progress system
in your server, there’s nothing built into Rails that will give you back
a real estimate of progress. So anything you do will likely be just a
cheat. The spinner is honest (says “I have no idea when, but not yet
done”).

Here’s a fake one I wrote a while back for a project using bootstrap and
Prototype.js

Ugh. Forgot the link:

gistfile1.js

document.on('click', 'input[name="commit"]', function(evt, elm){
  var f = elm.up('form');
  fake_progress = new Element('div', {className: 'progress progress-striped active', style: 'width: 100%; clear:both'});
  f.insert({before: fake_progress});
  var bar = new Element('div', {className: 'bar'});
  fake_progress.insert(bar);
  bar.setStyle('width: 2%');
  var rnd = 0.2
  function add_random(){
    rnd = Math.random();
