I'd like to have the 9 button (3x3) to get a color change after getting clicked, so i used a .btn:focus class where I set a bg-color and a text color. the problem is the fact that if I click somewhere else (in the blank spot of the page or in the radio type input below) this color change disappears, but I need it to be there. It should disappear only if I click a different button of the same group of 9 but I don't know how to do it.

I tried with a JS function in the lower part of the HTML code that should add to my 9 buttons a class that should color them but that doesn't work. (I've just realised that even if this last JS function would work, my problem would be the fact that if I click a button that is not the one already selected I'd have 2 different button colored. I don't know how to solve my problem.)

I have a problem with the update_post_meta function. I have a user submitted value, which I pass via $_POST and then saving to post meta.

All is working fine, but when the value is '0' the post meta is not updated.

In my software solution i use JavaEE with EJBs. On certain events i fire different events regarding what happend in the system. In my specific case i fire two different events that should be executed after the transaction finished successfully.

As far as i know the order of execution of the same event is not specified but how does CDI execute the events when they are different types and fired one after the other?

So in my code i do fire(Event) and then in the same transaction fire(Event). Is Event executed before Event? Researched this but i could not find an answer.

Here it is stated that the execution order of the same event is not a given but there is nothing about different events: http://www.next-presso.com/2014/06/you-think-you-know-everything-about-cdi-events-think-again/

I have built a Bootstrap form in Apps Script that sends the answers to a Google Spreadsheet.
Now, I would that when in a dropdown a user select a specific option, the form send the notification to specific mail address. In the specific case, the dropdown with "id=area".

when i choose an option from action sheet, it set a title label to button. But when i click another button with another action sheet, it cancel title label of first button. How can i set each button without cancel any title label?

This is how it works:

This is my code of two action sheets:

What I want is to change the accessibility order, the order in which the screen reader, the TalkBack in that Android case, read the elements, after pressing a button. This is what I tried by far, but it doesn't work, the order is still the initial descending ones. (In my example buttons are in order b1, b2, b3, and after I presso button changeorder I want the order to become b3,b1,b2).

I am trying to render some html, after executing a xml http request from index.html, but the server is not rendering my html page, even if the log seems to work just fine:

I am coding a page with Bootstrap 3. I have a container and inside it I placed a row, split into 2 columns (col-6) with centered text (text-align: center on the parent, cascading to every child). The problem is one of these 2 columns is too wide since has more text than the other. I then set the max-width to render them equally but now on the screen they are pulled on the left part of the screen, not perfectly centered. How to center them again mantaining the max-width property?
