php - html+jquery problem

Question

Make a function similar to answering questions. The problem now is that the first question was originally

Then I clicked on the second question after .1 (which is li)

Then mainly look at this traversal

I removed the li from the previous question first, and then added the new one, but I don’t know why there is only one

But it’s less than 1. Please help, what is the problem?

Answer 1

remove() is to clear everything and move it out of the loop

Answer 2

You just need to remove li outside $.each. Because you perform the remove operation every time you loop, there is only one left
