防止js alert()暂停计时器 [英] Prevent js alert() from pausing timers

问题描述

因此，我安排了一些计时器进行测验.事情是，我刚意识到我放

So I made some timers for a quiz. The thing is, I just realized when I put

javascript: alert("blah");

在地址中，弹出警报框暂停我的计时器.在测验中这是非常不需要的.

in the address, the popup alert box pauses my timer. Which is very unwanted in a quiz.

我认为没有任何方法可以阻止这种行为...但是我还是要问.

I don't think there is any way to stop this behaviour... but I'll ask anyway.

如果没有，建议我该怎么办?

If there is not, mind suggesting what should I do?

推荐答案

显然，预览渲染与发布的渲染不同.该段是为了确保接下来的两行显示为代码.

Apparently the preview rendering differs from the posted rendering. This paragraph is here to make sure the next two lines show up as code.

// Preserve native alert() if you need it for something special
window.nativeAlert = window.alert;

window.alert = function(msg) {
    // Do something with msg here. I always write mine to console.log,
    // but then I have rarely found a use for a real modal dialog,
    // and most can be handled by the browser (like window.onbeforeunload).
};
