找不到jQuery方法

Question

I'm changing the following script in order to work with jQuery: http://www.w3schools.com/html/html5_draganddrop.asp .

drag = function(ev) {
        console.log("started drag", ev.target);
        console.log('$(ev.target).parent()[0]',  $(ev.target).parent()[0]);
        console.log(' $(ev.target).parent()[0].attr(\'id\')',  $(ev.target).parent()[0].attr('id'));


    }

Can someone explain why I get an Uncaught TypeError: undefined is not a function in the last log? (attr method)

Answer 1

Try,

$(ev.target).parent().attr('id')

The error is raising because .attr() is not a native javascript function.
