Question

I was given these set of practice instructions:

Write a selector which finds the UL within the tasks div and store this into a variable named task_list.

    var task_list = $('div#tasks ul');

then the next one got me confused:

Write a second selector line which finds all children within task_list that have the class name completed. Store this into a variable named all_completed.
Use the detach() method. Call detach() on your all_completed variable.

     var all_completed = $(task_list).children('li.completed').detach();

or

   $(all_completed).detach(task_list);

Can someone please help me? Is this asking me to create a variable and use it as a selector in jQuery? If so, how do I do this??

Answer 1

task_list is already a jquery object, you don’t need to re-jquery (is that a term?) it.

var all_completed = task_list.children('li.completed').detach();
