问在Chrome控制台调试时如何更改js局部变量的值

EN

function foo() {
  var bar = 42;
  // Normally, you don't have to use a hardcoded breakpoint like
  // the one that follows, you can set a breakpoint from within the
  // debugger just by navigating to the line of code and clicking in
  // the left-hand gutter. But in Stack Snippets the easiest way to
  // do one is to use the debugger statement:
  debugger;
  // Now, when stopped on the breakpoint, type this in the console:
  // bar = 67;
  // ...and press Enter.
  // Then hit the arrow button to allow the script to continue
  console.log(bar); // ...and this will log 67 instead of 42.
}
foo();
