Why won't Google Chrome's script debugger let me set a breakpoint?
提问by Kev
I'm running Google Chrome 8.0.552.215 on Windows 7 x64 Ultimate. I have a simple jQuery inline script much like any I've successfully debugged in the past:
我在 Windows 7 x64 Ultimate 上运行 Google Chrome 8.0.552.215。我有一个简单的 jQuery 内联脚本，就像我过去成功调试过的任何脚本一样：
<script type="text/javascript">
$(document).ready(function () {
// do stuff here
// but reduced to a simple
alert('here!');
});
</script>
I'm browsing to the secure (https) section of the site I'm working on.
我正在浏览我正在处理的网站的安全 (https) 部分。
There are no script errors, the scripts all run just fine, but I can't set a breakpoint.
没有脚本错误，脚本都运行得很好，但我无法设置断点。
I tried debugging this in Firefox's Firebug and and can set and hit breakpoints just fine.
我尝试在 Firefox 的 Firebug 中调试它，并且可以很好地设置和命中断点。
Why would this happen?

This bug was fixed yesterday (February 3) with the introduction of a new api for managing JavaScript breakpoints: http://code.google.com/p/chromium/issues/detail?id=69988
此错误已于昨天（2 月 3 日）修复，引入了用于管理 JavaScript 断点的新 API：http: //code.google.com/p/chromium/issues/detail?id= 69988
I downloaded the most recent Chromium nightly from http://build.chromium.org/f/chromium/snapshots/and was able to successfully set breakpoints in JavaScript, which I had been unable to do using the current stable/beta/dev builds of Chrome.
我每晚从http://build.chromium.org/f/chromium/snapshots/下载了最新的 Chromium，并且能够在 JavaScript 中成功设置断点，而使用当前的 stable/beta/dev 版本我无法做到这一点铬。
Hopefully this fix will be incorporated into the next releases of Chrome. Until then, adding debugger; statements to your code is a decent workaround for setting breakpoints.
希望此修复程序将合并到下一个版本的 Chrome 中。在此之前，添加调试器；代码中的语句是设置断点的一个不错的解决方法。

Does this happen when you refresh the page when the developer tools are already open? It happened to me too in that case.
在开发者工具已经打开的情况下刷新页面会发生这种情况吗？在这种情况下，它也发生在我身上。
Workaround:
解决方法：
Set resource tracking to always enabled.
Close the developer tools.
Refresh the page.
Open the developer tools, tab resources.
Set your breakpoint.
File a bugreport herebecause it is not normal behavior.
Post a link to this bugreport back on SO so we can all star it.
