Question

I have the following javascript code:

var oLink = {
        title:   $link.attr('title') || '',
        row:     $link.attr('data-row') || ''
    }

Is it possible to add another field once these fields have already been defined so as to achieve:

var oLink = {
        viewUrl: $link.attr('data-href') || '',
        title:   $link.attr('title') || '',
        row:     $link.attr('data-row') || ''
    }

Answer 1

Always.

There is practically never a time that this wouldn’t work.

var myObj = { x : 0, y : 1 };
myObj.z = 2;
myObj["A"] = { x : 0 };

Now you’ve got:

{
    x : 0,
    y : 1,
    z : 2,
    A : { x : 0 }
}
