无法从setTimeout调用警报 [英] can not get alert to call from setTimeout
问题描述
有没有理由说这个代码不会提示有人每隔5分钟保存一次他们的工作？它似乎没有工作。此代码在HTML文档的HEAD中显示
。
函数saveYourWorkReminder（）{
alert（" It已经过了5分钟。请保存你的工作。网页浏览器是b
越野车经常崩溃。保护自己！）;
}
setTimeout（" saveYourWorkReminder"，300000）;
Is there any reason why this code wouldn''t prompt someone to save their
work every 5 minutes? It doesn''t seem to be working. This code shows up
in the HEAD of an HTML document.
function saveYourWorkReminder() {
alert("It''s been 5 minutes. Please save your work. Web browsers are
buggy and crash often. Protect yourself!");
}
setTimeout("saveYourWorkReminder", 300000);

为什么这段代码不会提示有人每隔5分钟保存一次工作？它似乎没有工作。此代码显示在HTML文档的HEAD中。

警告（它已经过了5分钟。请保存您的工作。 Web浏览器经常出现问题并且经常崩溃。保护自己！）;

或许缺少括号？
setTimeout（" saveYourWorkReminder（）"，300000）;
BTW，你的是什么互动的观众使用Web浏览器，需要
他们来保存他们的工作？他们将节省什么以及如何在以后检索
？
Perhaps missing parentheses?
setTimeout("saveYourWorkReminder()", 300000);
BTW, what does your inteneded audience do with a Web browser that require
them to save their work? What would they save and how would they retrieve
it later?

是否有任何理由为什么这段代码不会促使有人每5分钟节省一笔
的工作？它似乎没有工作。此代码在HTML文档的HEAD中显示
。
函数saveYourWorkReminder（）{
警告（它已经过了5分钟。请保存您的工作。 Web浏览器经常出现问题并且经常崩溃。保护自己！）;
}
setTimeout（" saveYourWorkReminder"，300000）;

也许缺少括号？
setTimeout（" saveYourWorkReminder（）"，300000）;
Perhaps missing parentheses? setTimeout("saveYourWorkReminder()", 300000);
（剪辑）
你可以使用函数指针（没有括号的函数名），但
它是变量名，因此不带引号：
setTimeout（saveYourWorkReminder，300000） ;
警报字符串需要在一行（可能就在你所在的地方）。
为什么不弹出一个链接到一个不错的网页浏览器：o

不要只参加USENET ......获得奖励！
(snip)
You can use a function pointer (function name without parentheses), but
it''s a variable name and so takes no quotes:
setTimeout(saveYourWorkReminder, 300000);
The alert string needs to be on one line (probably is where you are).
Why not pop up a link to a decent web browser? :o

谢谢。我会这样写的：
setTimeout（" saveYourWorkReminder（）"，300000）;
当你说' ;体面的网络浏览器你是在谈论一个允许你在一个textarea中保存你正在写的东西吗？也许是11个月之前我在网上讨论这个问题，并且在那个
时间似乎没有任何浏览器能够做到合理的工作
字处理器。有变化吗？你指的是什么？
Thank you. I''ll write it like this:
setTimeout("saveYourWorkReminder()", 300000);
When you say "decent web browser" are you speaking of one that allows
you to save the stuff you are writing in a textarea? I was in a big
online discussion about this problem perhaps 11 months ago and at that
time it seemed that there were no browsers that did a reasonable job as
word processors. Have things changed? What are you referring to?
