打破变量值的变化 [英] Break on a change of variable value
问题描述
与此处的其他问题类似,喜欢这个。
有没有办法打破任何JavaScript调试器中变量值的变化? (比如IE Developer工具,Visual Studio或Firebug)?
我想它就像是一个监视变量,但我希望能够看到callstack和当实际发生对变量的更改时暂停它。
另一种方法可能是使用自定义setter覆盖值设置,并在其中放置断点,但不幸的是这对IE AFAIK不起作用。
UPDATE
看来这种行为至少对于非托管代码是可用的写入C ++ 所以我想也许用C ++编写的javascript引擎(谷歌的V8)可能有类似的东西,但似乎没有我想要的东西。
如果您使用任何一个调试器,我强烈推荐Firebug。对于您的所有Javascript,HTML和CSS需求: - ):

Similar to other questions here, like this one.
Is there a way to break on the change of a variable value in any JavaScript debugger? (like IE Developer tools, Visual Studio, or Firebug)?
I guess it's something like a "watch variable", but I want to be able to see the callstack and pause it when the change to the variable actually occurs.
An alternative approach might be to override the value setting with a custom setter, and put a breakpoint in that, but unfortunately that won't work for IE AFAIK.
UPDATE It appears that this type of behavior is available at least for unmanaged code written in C++ So I thought maybe a javascript engine written in C++ (Google's V8) might have something similar, but that doesn't appear to have what I want either.
You don't even need an IDE - you can use "Object.watch()":
If you use any one debugger, I'd strongly recommend Firebug. For all your Javascript, HTML and CSS needs :-):
