在JS中暂停在Chrome中的代码执行。可能？ [英] Pausing code execution in chrome from within JS. Possible?

问题描述

我能否在JS代码中暂停执行？我正在研究一个简单的基于haxe的调试util，我希望能够通过调用一个util方法来模拟断点，这会触发执行暂停。

Can I pause execution from within JS code? I am working on a simple haxe-based debug util, and I want to be able to simulate breakpoints, by calling a util method which will trigger the execution pause.

推荐答案

不知道这是你想要的，但是在Chrome中（如果安装了Firebug，则为Firefox），你可以使用内置的JavaScript 调试器 声明。这导致执行暂停，并且实际上就像设置断点一样。例如，下面的代码在循环的每一次迭代中都会中断，从而允许您检查 i 的值（愚蠢简单的示例）：

Not sure if this is what you're looking for, but in Chrome (and Firefox if Firebug is installed) you can use the built-in JavaScript debugger statement. This causes the execution to pause, and is effectively like setting a breakpoint. For example, the following would break on every iteration of the loop allowing you to examine the value of i (stupidly simple example):

for(var i = 0; i < 10; i++) {
    debugger;
    console.log(i);
}
