Is there a way to force synchronous behavior in JavaScript like the alert() function does?
提问by Maxx
When using alert or confirm in Javascript, the browser is forced into a synchronous process where everything (even the loading of another page) halts until the user dismisses the dialog.
当在 Javascript 中使用 alert 或 confirm 时，浏览器会被迫进入一个同步过程，在这个过程中，一切（甚至是另一个页面的加载）都会停止，直到用户关闭对话框。
I was wondering if there was any other way to force the browser to halt/pause using JS or jQuery.
我想知道是否还有其他方法可以使用 JS 或 jQuery 强制浏览器停止/暂停。
I looked at similar questions such as:
我查看了类似的问题，例如：

...but none of the answers seem to address the issue head on. If there is not a way to do it, I will fully accept that as an answer.
...但似乎没有一个答案能正面解决这个问题。如果没有办法做到这一点，我将完全接受它作为答案。

No, there's currently no cross browser way to force an asynchronous function to execute synchronously.
不，目前没有跨浏览器的方式来强制异步函数同步执行。
However you may make use of continuations to write asynchronous code in a synchronous manner.
但是，您可以使用延续以同步方式编写异步代码。
