Find checkbox with a class of a variable JQuery

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');

Use the javascript console in Firefox or Chrome. You can execute statements to verify that your selectors are correct. — jrummell

@AmarPalsapure unless the input is what he's after. And considering input nodes don't usually have children, I'm guessing this is unlikely. — Joseph Marikle

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');

@CecilTheodore could it be that you are using #box2 but looking under #box1?

Ignore that last comment, today has been a BAD day! thanks for your help youve helped me work it out.

It will depend on the value of preciseClass; if you have multiple class applied to box2 element : it will not work as you expect.

can you make an alert or a console.log of the value? http://jsfiddle.net/bxeys/

I think you may need a space after :checkbox

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

no... the . classname will cause it to look for any classname nodes, which probably don't exist.
