jQuery ajax async: false 导致一个奇怪的警告? [英] jQuery ajax async: false causes a strange warning?
问题描述
在我的 JS 应用程序中，我有许多带有 async: false 的 Ajax 调用.我正在使用最新的 Chrome 浏览器，最近在我的控制台中出现以下警告.
In my JS App, i have many Ajax calls with async: false. I am using latest Chrome browser and in my console below warning appears recently.
主线程上的同步 XMLHttpRequest 被弃用，因为其对最终用户体验的不利影响.如需更多帮助，检查 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, check http://xhr.spec.whatwg.org/.
现在我正在尝试将所有 async: false 更改为 async: true.但它会导致很多错误，因为我的应用程序需要使用 async: false 运行.
Now i am trying to change all async: false to async: true. But it causes a lot of error because my app needs to run with async: false.
警告只是一个错误还是什么?我可以担心还是忽略它?
Is the warning just a bug or something? Can i worry about that or ignore that?

Is the warning just a bug or something?
不，这不是错误.出于消息中所述的原因，同步请求确实已被弃用.
No, it's not a bug. Sync requests are indeed deprecated, for the reasons stated in the message.
我可以担心还是忽略它?
Can i worry about that or ignore that?
您应该听取建议并对您的应用进行适当的更改(是的，这并不像将 async: false 更改为 async: true 那样简单).
You should heed the advice and make the appropriate changes to your app (and yes, it's not as simple as just changing async: false to async: true).
也许这有助于更好地理解异步操作:
