Setting object keys from variables

Question

in javascript is it possible to construct an object literal with expressions evaluating to strings for property names?

I am having a problem setting object keys and values from variables, if I set just the key or just the value from a variable it works fine if I set them both from variables it does not work.

This works fine

 $(":input").change(function () { 

    var currentId = $(this).attr('id');
    var currentval = $(this).attr('value');

    $.post("/inside/update.php", {
        "profile_age":currentval 
    });
});

This configuration does not work

$(":input").change(function () { 

    var currentId = $(this).attr('id');
    var currentval = $(this).attr('value');

    $.post("/inside/update.php", {
        currentId:currentval 
    });
});

FYI, there is no JSON in your code. You are dealing with JavaScript *object literals*. — Felix Kling, Oct 12 '12 at 17:59
No worries, just pointing it out! JSON looks similar to JS object literals, so the confusing is understandable (and in fact pretty common (unfortunately)). — Felix Kling, Oct 12 '12 at 18:09

Try this:

var options = {};
options[currentId] = currentval; 
$.post("/inside/update.php", options);
