Update sample output of a custom date via ajax

[nacin]

On Settings > General, we have instructions for users to "Click “Save Changes” to update sample output."

We should update the example via ajax when the input box that takes a PHP date string loses focus.

Proof of concept.

Need to handle $_POST better in admin ajax.

(In [15757]) Update via ajax the sample output of custom date/times on options-general. fixes #12636.

I think we need to improve this. Now:

1. The required action to have the sample output updated is not intuitive (and the UI offers not hint on what you need to do).
2. More importantly, the workflow is not good.

Can’t we have the request sent after a small delay, so that you receive feedback while your cursor is still in the input box?

[nacin]

To be honest, I don't think the UI needs to hint. I think this is still a huge improvement over 3.0.

I don't have a problem with firing off the ajax request after a delay.

Let's iterate again in 3.2 dev cycle with the delay (only if changed, obviously). Done with it for 3.1.

Found another issue with this.

Try checking the radio box "Custom", enter a custom date / time format. Then click on another radio box (a preset format) instead of clicking randomly outside of the text input. The format inside of the text input is changed properly to that of the preset format, however, the ajax request is already sent and an invalid sample output appears.

This ticket has been sitting for quite a while and the spirit seems fixed in 3.1. Additional issues or enhancement are likely better off as new tickets at this point.
