Variable jquery parameter name

Question

I have a set of PHP language files which I use to output text to the user based on the their language choice. I have passed the PHP variables to javascript successfully and they are available as LANG You can see it in use in the code.

Here is my question... Since the code as shown below works perfectly, why can I not change this line...

'No': { 'class' : ''}}

to

LANG.no: { 'class'  : ''}}

Basically I want to know why I can use LANG elsewhere in the code but not in the line shown above or in the equivalent "Yes" line.

Here is the working code:

$.confirm({
    'title': LANG.return_to_exhibit_lobby,
'message': "<strong>"+LANG.return_to_exhibit_lobby_confirmation+"</strong>",
'buttons': {
'Yes': { 
    'class': 'special',
    'action': function(){
        window.location.href='logout.php';
    }},
'No': { 'class' : ''}}
});

Why? Because the confirm code expects "No"? and it would need to look like Lang : { no : { class... } } — epascarello

@epascarello I don't think that is true because I could change it to something absurd like 'banana'. I just can't but a variable name... Only a string. It can be anything... doesn't have to be "No" — G-J

@epascarello I tried the code as you suggested and it outputted "LANG" instead of "No" — G-J

What you could do instead:

var params = {
    'title': LANG.return_to_exhibit_lobby,
    'message': "<strong>"+LANG.return_to_exhibit_lobby_confirmation+"</strong>",
    'buttons': {
        'Yes': { 
            'class': 'special',
            'action': function(){
                window.location.href='logout.php';
             }}
};

params.buttons[LANG.No] = { 'class' : ''};

$.confirm(params);

That's because you're in an object literal. Syntax rules are different there because you are declaring a structure, not acting on it. You could do this:

var data = {
    'title': LANG.return_to_exhibit_lobby,
    'message': "<strong>"+LANG.return_to_exhibit_lobby_confirmation+"</strong>",
    'buttons': {}
};
data.buttons[Lang.No] = { 'class' : ''}
$.confirm( data );

You need to declare buttons first. params.buttons = {} or do as I did in my edited answer

@SimonBoudrias I saw that just before you posted that I forgot to do it. I fixed it and it works now. Thanks!
