default sort on page load ignores direction

[kickofitall]

A descent sorting on page load seems impossible because of the check for a different column.

The sort function with direction 'desc' still sorts the column in ascending order:
$('table.sortable').tablesort().data('tablesort').sort($("th.default-sort"), 'desc');

Changing the following line fixed that issue for me:
https://github.com/kylefox/jquery-tablesort/blob/master/jquery.tablesort.js#L42

from if (this.index !== th.index()) {
to if (this.index !== null && this.index !== th.index()) {

Thanks for pointing this out — a CodePen demonstrating the issue would be helpful, and a pull request would be even better because I likely will never have time to patch this myself 😁

Thanks for your answer.
I'm trying to make both in the coming days ...

I made a demo on CodePen: http://codepen.io/anon/pen/ozyVXY
In the JS in line 139 is the init for descent sorting, but the table is "wrong" sorted.
The fix is in line 42/43 on JS.
If my assumption is correct I will make a pull request.

I noticed this too and your fix did fix it! Thanks.

Experienced the same problem, the proposed code-change fixed it 👍

The proposed solution creates a new bug: tablesort.index returns null always.

Can you be a bit more specific?

[N2481]

With the proposed solution, this code stop working: tablesort.index is allways null:

$('#userList').on('tablesort:complete', function(event, tablesort) {
orderByColumn = tablesort.index;
direction = tablesort.direction;
});

Sorry, but I can't reproduce your problem.
If I add your code to my CodePen demo, the tablesort.index is switching between 0 and 1 after sorting the columns.
Can you provide a CodePen demo for this issue?

[N2481]

I added my code to your CodePend demo, please check it here:

You are right! I think this should solve the problem:
https://codepen.io/anon/pen/wbpqER
I split the [if/else if] in two if-blocks at line 48 and reset the if-statement on line 43 to it's original version.

[N2481]

Ok, it's working. But now, when you click on a column, the default sort is DESC, before was ASC.
Thank you for your help.

[kickofitall]

Just rename the "asc" to "desc" on line 44.
