当我在页面中调试JavaScript代码时，我的Chrome浏览器提示断点在错误的行中

Question

I use google chrome for many years. Recently I use chrome to debug JavaScript code in my project, I just set the breakpoint using chrome dev-tool that these breakpoints seems to be ignored, but the js function certainly be executed. My JS code and the breakpoint position like this picture: js breakpoint can't be hint

When I the breakpoint is hinted, the hint line is the wrong line and the variables are present the message "xxx is not defined": hint breakpoint in the wrong line

My OS is Windows 10, chrome edition is 72.0.3626.119.

Answer 1

One Possible reason for that is by mistake you might have the Deactivate Breakpoint enabled. Because of that the chrome debugger not stopping on any breakpoints. Attaching 2 image for references, where the first one is enabled for breakpoints Image with enabled breakpoints and the second one Image with disabled breakpoints is disabled.
