Question

I need to find a checkbox with a class that is contained within the variable preciseClass.

My attempt below is not working. Where am I going wrong?

var preciseClass = $('#box2').attr('class');


$('#box1').find('li input:checkbox.' + preciseClass).attr('checked', 'checked');

Answer 1

Could be that the node has multiple classes in which case you might be able to use something like this:

var preciseClass = $('#box2').attr('class').split(" ").join(".");

$('#box1').find('li input:checkbox.' + preciseClass).attr('checked', 'checked');
