Answer 1

The only way to assign properties with dynamic names to an object is to use array syntax

 var myButtons = {};
 myButtons[myi18n.close] = ...

Answer 2

You can't reference variables in key names in object literal, so you need to create your object first, fill it using regular [] notation and then just use it in $.modal .

buttons = {}

buttons[myI18n.close] = function(win) {
   // ....
}

$.modal({
    buttons: buttons
});

Answer 3

You can't use an object literal directly with a variable key. You'll need to separate out your code to use the array access syntax ( obj[keyname] = value ).

var obj = {
        buttons: {}
    };
obj.buttons[myI18n.close] = function () {...};
$.modal(obj);

Alternatively, you could use a module pattern:

$.modal({
    buttons: (function () {
        var btns = {};
        btns[myI18n.close] = function () {...};
        return btns;
    }())
});
