Improved AJAX support

[Fervens]

The pager previously had some support for AJAX paging. This patch fixes issues with update events being re-triggered continuously and AJAX error handling being bound too many times. It also adds support for passing filtering parameters with the AJAX request. If you have any issues/suggestions with the patch please let me know.

Oh man, I didn't see this pull request until I just pushed a fix for the pager. I'll have to look at what you've done.

Thanks for all the work you've done!

note, people really need to stop changing line endings... makes it hard to diff the actual changes.

Thanks @thezoggy! I'll look into doing the normalization in the next update too :)

[Fervens]

Thanks @thezoggy, I'll be sure to be more careful with the line endings in the future.

Keep up the good work @Mottie.

It appears that I accidentally included an unrelated change that I was using to hide table filter inputs on hidden columns. This causes some trouble if your table is hidden on page load though, so you'd probably want to avoid including this.

505 - t += '<td>';
506 + t += '<td' + (c.$headers.eq(i).is(':visible') ? '' : ' style="display: none"') + '>';

@dhamma I hate to ask, but can you resubmit this pull request so I can merge it with the current version. It'll speed things up for me in these days of very limited time. That, and I still need to learn how to cherry pick a pull request 😋

[Fervens]

Alright, it looks like the changes automatically pulled into here, and the line endings look better.

[thezoggy]

id say rebase and push a new one. otherwise you will have some dirty commit history and git blame will always show you as you changed the files one way then back

[Fervens]

It looks like the blame shows up alright on the site and on my windows box; though, I haven't checked on a linux box. I can rebase if you'd like @Mottie, just let me know.

Hi @dhamma!

Yeah, I was looking over the mess in the history and I agree with @thezoggy about using rebase to clean up the history.

Thanks again for all your hard work!

[Fervens]

I was having trouble figuring out how to rebase since I had previously merged, so I ended up just applying the merged changes in a single commit.
