javascript - How can I tell whether an element matches a selector?

Question

Let's say I've got a DOM element - how can I tell whether it matches a jQuery selector, such as p or .myclass? It's easy to use the selector to match children of the element, but I want a true/false answer to whether this particular element match?

The element may not have an ID (and I can't assign it a random one for reasons beyond this), so I can't apply my selector to the element's parent and look for children with the same ID as mine.

Will this work as intended? I can't figure out Javascript object comparisons.

$(selector, myElement.parentNode).each({
  if (this == myElement) // Found it
});

Seems like there would be an easy way to see whether a DOM element matches a jQuery selector...

You can use the is() method:

if($(this).is("p")){
 // ...
}
