google-apps-script - while debugging, stop when a variable changes its value

Question

Is there a way to stop the execution of a script when a variable (say, an iterator like 'i'), changes its value?

Of course, I know you can set a breakpoint at some lines, but I would want just to set a variable, and when it changes, stop the program for debuggin.

Answer 1

尝试使用debugger，例如：

function testDebugger() {
  var i = 10;
  while(i--) {
    if (i === 5) debugger;
    Logger.log(i);
  }
}

请记住从编辑器开始，使用“调试”而不是“运行”。

Answer 2

这是不可能的。但是，如果您使用像 setValue 方法这样的包装器，您可以按照我上面的答案执行，或者抛出“hello”，它也会进入调试器。
