How to add javascript variable in the commands

Question

Is there any way to add the variable into the jQuery command like this :

var id = 10;
var msg = CKEDITOR.instances.contentedit+id.getData();

I expect

CKEDITOR.instances.contentedit10.getData();

from the code above

But it does not work for me and caused the errors as it does not properly add the variable to the command.

By googling ["*dynamic property name javascript*"](http://stackoverflow.com/questions/4244896/dynamically-access-object-property-using-variable). — h2ooooooo, Feb 02 '15 at 18:14

You can do this:

var msg = CKEDITOR.instances["contentedit" + id].getData();

The [ ] operator does exactly the same thing as ., but it allows any expression instead of just an identifier.

@BhojendraNepal because it would be an error if it were not. – Pointy Feb 02 '15 at 18:14
@BhojendraNepal no, "contentedit" is part of the name of the property. It has to be a string. The only variable involved is "id". – Pointy Feb 02 '15 at 18:15
A variable, appended to the string "contentedit" to create the full name, thus the quotes. – ssube Feb 02 '15 at 18:15
