She is firefox 23 and mine is 16.0.1. I’m glad to finally get to the bottom of the problem.

A week later, this problem is no longer present when accessing resources on the server using the same browser. Keep going. Fortunately, I don’t know where the inspiration came from, the original introduction of jquery.js into jquery.1.7.2. min.js, the problem was finally solved again. I don’t know if it will be overthrown, hehe ~ ~
