Timed alert box pop up for website?
提问by BLS93
For my website I would like an alert box message to appear 4 seconds after the page is opened. I cant figure out how to do this as the timed function works if a button is clicked but I would like the alert box to pop up automatically withoutt any user input/button and then shut when the user clicks "okay"...
对于我的网站，我希望在页面打开 4 秒后出现警告框消息。我无法弄清楚如何做到这一点，因为如果单击按钮，定时功能会起作用，但我希望警报框在没有任何用户输入/按钮的情况下自动弹出，然后在用户单击“好的”时关闭...
Any ideas or posts related to this topic would be great help!

function showPopup()
{

In it's most simple form:
最简单的形式：
setTimeout(function(){alert("Hello")},4000);
4000 = 4 seconds
4000 = 4 秒

If you want an alert to appear after a certain about time use this code:
如果您希望在一段时间后出现警报，请使用以下代码：
setTimeout(function() { alert("Your Message"); }, time);
