JavaScript - Get object property from element data

Question

I'm wondering if that's possible to get object property from element data.

So let's say I 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, is there any way I can do this?

Answer 1

你似乎想要

alert(obj[test]);

Answer 2

Try to use [] :

alert(obj[test]);
