javascript - How to determine whether an element is in a transitional state?

Question

Is there such an attribute? Can you tell whether an element is in a transitional state? Now I mark it by adding attributes to each transitioned element in the transitionend event

Answer 1

You can monitor the following separately, and then use variables to control the status yourself.

transitionrun //Ready to start
transitionstart //Start, there may be delaytranstionend //End between
run and start
