chrome调试器调用堆栈异步选项是什么意思? [英] what does chrome debugger call stack async option mean?

问题描述

我在 call stack 标头上看到了此选项，尽管我勾选了该选项，但我不知道它的含义，以及勾选该选项的含义.

I saw this option on the call stack header, although I am ticking it on, I don't know what does it mean, and what's the implication by ticking it on .

推荐答案

它对于调试异步JavaScript很有用.它使您可以查看整个调用堆栈，并遍历事件侦听器(setInterval，setTimeout，XMLHttpRequest等)的堆栈跟踪.我发现它对于通过每个异步调用监视变量的值特别有用.

It's useful for debugging asynchronous JavaScript. It let's you view the entire call stack and walk the stack trace for event listeners ( setInterval, setTimeout, XMLHttpRequest and others ). I've found it particularly useful for watching the value of my variables through each async call.
