One-step debugging with breakpoints when debugging code will inexplicably jump to the project-independent JS and then never come back, as shown in Figure
ps：The red box is the JS used by the project; the Yellow frame is the other JS that appears when debugging, some like the code of the browser plug-in I used, and some don’t know what it is;
How to solve the above problems
It may be the browser cached JS. Do you try to cache the cache clearly?
A single step breakpoint is a method and one way to go, so you may call something else Js, and then jump to other JS.
You break a point in the place where you want to stop, then press F8 to stop where you want.
