JavaScript的执行console.log导致错误：＆QUOT;在主线程同步XMLHtt prequest是德precated ...＆QUOT; [英] Javascript console.log causes error: "Synchronous XMLHttpRequest on the main thread is deprecated..."
问题描述
我已经添加日志到控制台检查不同变量的状态，而无需使用Firefox的调试器。
I have been adding logs to the console to check the status of different variables without using the Firefox debugger.
不过，在很多地方我在 main.js 文件中添加的console.log ，我收到以下错误，而不是我的可爱的小手写的消息对自己说：
However, in many places in which I add a console.log in my main.js file, I receive the following error instead of my lovely little handwritten messages to myself:
在主线程同步XMLHtt prequest是因为其不利影响到最终用户的体验pcated德$ P $。如需更多帮助 http://xhr.spec.whatwg.org/
Synchronous XMLHttpRequest on the main thread is deprecated because of its detrimental effects to the end user's experience. For more help http://xhr.spec.whatwg.org/
什么替代品或包装为的console.log 我可以添加到我的code使用不会导致这个错误？
What alternatives to or wrappers for console.log can I add to my code use that will not cause this error?
我是否做错了？
推荐答案
这发生在我身上时，我是懒惰，其中包括一个脚本标记，正在返回的内容的一部分。因此：
This happened to me when I was being lazy and included a script tag as part of the content that was being returned. As such:
部分HTML内容：
<div>
SOME CONTENT HERE
</div>
<script src="/scripts/script.js"></script>
它的出现，至少在我的情况下，如果返回通过XHR HTML内容那样，你将导致jQuery来拨打电话，以获取该脚本。这调用发生与异步标志false，因为它假设你需要的脚本继续加载。
It appears, at least in my case, that if you return HTML content like that via xhr, you will cause jQuery to make a call to get that script. That call happens with an async flag false since it assumes you need the script to continue loading.
在像这样的你会通过寻找到某种形式的有约束力的框架，只是返回一个JSON对象，或根据您的后端和模板，你可以改变你的加载脚本得到更好的服务情况。
In situations like this one you'd be better served by looking into a binding framework of some kind and just returning a JSON object, or depending on your backend and templating you could change how you load your scripts.
您也可以使用 jQuery的 getScript加入（） 来抢相关的脚本。这里是一个小提琴，这是jQuery的例子只是一个单纯的拷贝，但我没有看到剧本时加载这样的警告异常。
You could also use jQuery's getScript() to grab relevant scripts. Here is a fiddle, It's just a straight copy of the jQuery example, but I'm not seeing any warnings thrown when scripts are loaded that way.
