jquery find element by specific class when element has multiple classes

Question

So I am working on something that wasn t well thought out in the build from the backend team  That leaves me with a document full of divs    What I am doing is rolling back from the element I need to click on  get the parent container then find an element within the parent which has class  alert-box warn   class  alert-box dead   etc    Essentially  I m trying to use multiple class selectors on each element  When I try to find just alert-box it doesn t seem to be working right  I m assuming because it has warn dead    fine  etc      How can I find just alert-box  or equivalent to a wildcard concept

You can combine selectors like this      alert-box warn   alert-box dead      Or if you want a wildcard use the attribute-contains selector      class   alert-box        Note  Preferably you would know the element type or tag when using the selectors above  Knowing the tag can make the selector more efficient      div alert-box warn  div alert-box dead       div class   alert-box
