Getting nested data attributes with jQuery

Question

I'm trying to do something like this with the data method:

$("body").data("bar", { myType: "test", count: 40 });

However, I can't seem to set "count" like this:

$("body").data(bar["count"], 41);

Is my syntax wrong?

You cant do $("body").data(bar["count"], 41); first argument need to be a string. — RafH

The syntax is .data( key, value ). data(bar["count"], 41);is equal to data(40, 41);.

If you want to change the value of your object you can do $("body").data("bar").count = 41

Looks like you need to use it like this:

$("body").data({ baz: [ 1, 2, 3 ] });

// then

var data = $("body").data();
console.log(data.baz);  // outputs the array [ 1, 2, 3 ]
