JavaScript - Get object property from element data -

i'm wondering if that's possible object property element data.

so let's have element:

<div data-item="objprop" class="test">test</div> 

and js object:

var obj = { objprop: true } 

i tried to:

var test = $('.test').data('item'); alert(obj.test); 

so, yeah, there way can this?

you seem want

alert(obj[test]);
