Finding all checkboxes are checked in jQuery

Question

I have a collection of checkboxes ``` ``` I would like to write some jQuery to check if all checkboxes are checked then perform an action but how?

Accepted Answer

Like this:

```
if (!$('input.paid[type=checkbox]:not(:checked)').length)
    do('stuff');
```

This will check if there are any that are unchecked, and do stuff if there aren't (i.e. they are all checked).
