Finding ancestor with specific attribute or class in jQuery

Question

I have a DOM element elem that has an ancestor element which has the class myClass (alternatively an attribute with some name). The problem is that I need to find this ancestor easily with jQuery. Currently, I am stuck with ugly trial-and-error stuff like

var ancestor = $(elem).parent().parent().parent().parent().parent().parent().parent();

If the HTML code changes, the jQuery code easily breaks.

Is it possible to find the ancestor element with more elegant jQuery code?

Answer 1

Use closest(). it will traverse up the DOM from the current element until it finds a parent element matching the selector you provide.

var ancestorByClass = $(elem).closest(".myClass"); // by class

var ancestorByAttribute = $(elem).closest('[href="#foo"]'); // by attribute

Answer 2

Only class solution is presented, but not the attribute one.
