javascript - 如何在 javascript 中的警告框后面运行脚本？

Question

我想在 alert("hello") 之后的 3 秒内运行 alert("hi") 而无需单击“hello”警报的 OK。

这是我的代码:

$(function(){
    alert("hello");
    setTimeout(function(){
        alert("hi");
    },3000)
})

如果您阅读 doc你会明白这是不可能的:

Notes

The alert dialog should be used for messages which do not require any response on the part of the user, other than the acknowledgement of the message.

Dialog boxes are modal windows - they prevent the user from accessing the rest of the program's interface until the dialog box is closed. For this reason, you should not overuse any function that creates a dialog box (or modal window).

Chrome users (e.g. extensions) should use methods of nsIPromptService instead.
