Question

我的老板要求提供一个不会更改的页面，以便加载两个定时弹出窗口。我找到了代码并将其编辑为我认为它应该做的事情，但它只加载了最后一个onLoad事件。我是一名设计师，我帮助制作网页，但Javascript远远超出了我的理解范围。我已经学会了如何使用单个弹出窗口并花费了很多时间来学习超时，但我似乎无法使用多个弹出功能。如果你有片刻，你会看看吗？谢谢:)）

我稍微清理了你的代码，并创建了闭包来更好地处理你的settimeout 如果你必须修改它，我想你会发现以这种方式调用settimeout更容易（你会遇到更少的全局变量问题）。

你需要一个闭包来使window.close在超时工作。如果你只使用浏览器至少在FF3.6上打开html文件，这不会起作用，但你可以把它放在你的网络服务器上。

首先，让我向你表示哀悼，因为有一个老板命令你使用弹出窗口...他们很讨厌:(无论如何，如果你想吓唬游客，我想这取决于你。所以这里去了：

你用超时覆盖url变量。以下是在Firefox中为我工作的：

                preview = window.open(URL1, "preview", windowprops);
