为什么 Visual Studio javascript 断点在萤火虫中不起作用？

Question

Why can't microsoft make setting a breakpoint in visual studio equivalent to adding the "debugger" keyword in javascript? I want to test javascript cross browser in a unified way.

Answer 1

Use the debugger keyword instead of setting breakpoints.. if the debugger is enabled, it will break...

debugger; //breakpoint here

As to why they don't work. Firefox doesn't use the MS scrpting engine,so the VS debugger doesn't attach to Firefox.

Answer 2

Use debugger;

or Sys.Debug.assert() which will hit a debugger statement if assert fails
