I have looked for it in hundreds of degrees before, and it is basically a two-tier div > p, but now I have more than two layers of demand. I have thought about finding the parent element of ev.target, but if the nesting is a little deeper, it will be very troublesome, and I also consider that if I look for a parent element, the parent element of span is a, and the parent element of an in front is p, so I can"t accurately monitor the event of p. What can I do to solve this problem?.

if you want to use event delegates, you have to consider a variety of situations:
separately judge that event.target.tagName is "DIV A SPAN", and find the values of parent elements at different levels.
