HTML div 可以移出浏览器窗口吗？

发布于 2024-08-26 06:33:09 字数 4129 浏览 7 评论 0原文

我正在研究 ASP.NET Web 部件，它有一个“下拉”div。它一直在页面的右侧。当我单击将其调出时，它就会从窗口中消失。通常，任何超出可视区域的内容都会触发底部滚动条。这怎么可能？

替代文本

编辑：它是 Internet Explorer 8。下面是带有一些上下文的标记。我认为相关的是 id=WebPart_wp774658725VerbsMenu。默认情况下不显示。当您单击 td/span Verbs/span VerbsPopup（可以是任何）时，它会显示“下拉菜单”。在开发人员工具中，我没有看到任何 JavaScript 附加到这些元素，但如果我调试它，我会看到它正在运行一些。

I was playing around with ASP.NET Web Parts which has a "drop down" div. It's all the way to the right of the page. When I click to bring it up, it goes off the window. Usually anything off the viewable area will trigger the bottom scrollbars. How is this possible?

alt text

Edit: It's Internet Explorer 8. Below is the markup with some context. The relevant one I think is id=WebPart_wp774658725VerbsMenu. By default it doesn't display. When you click on the td/span Verbs/span VerbsPopup (it could be any), it shows the "dropdown". In Developer Tools I don't see any JavaScript attached to those elements, but if I debug it I see it running some.

确实是 createPopup 方法起到了作用。这是 Internet Explorer 中的专有方法。

请参阅 http://msdn.microsoft.com/en -us/library/ms536392%28VS.85%29.aspx。

It is indeed the createPopup method that does the trick. It's a proprietary method in Internet Explorer.

为什么不在此处添加一点额外的边距呢？似乎是节省时间的最简单、最便宜的方法。

Why not add a little extra to the margin there? Seems like the most easiest and cheapest way to save time.
