提问by Sarah
Hello guys I know that is probably a stupid question but i had to be sure after all. Can i add an input of type password in a prompt box? prompt box is a one of javascript's Popup boxes.(Alert,Confirm and Prompt)
大家好，我知道这可能是一个愚蠢的问题，但毕竟我必须确定。我可以在提示框中添加密码类型的输入吗？提示框是 javascript 的弹出框之一。（警报、确认和提示）

No, you can't.
不，你不能。
The popup is browser controlled and can't be changed.
弹出窗口由浏览器控制，无法更改。
As the documentationshows, you can only supply a message and default text.
如文档所示，您只能提供消息和默认文本。
You can use javascript to create your own overlay that simulates a prompt popup.
您可以使用 javascript 来创建自己的叠加层来模拟提示弹出窗口。
See the jQuery UI Dialogfor ideas and examples.

If you literally mean the promptfunction, you can't. What you can do instead is pop up a divor similar above the main content of your page (using absolute positioning and a z-indexvalue) and put the password box in there.
如果你从字面上的意思是prompt功能，你不能。您可以做的是div在页面的主要内容上方弹出一个或类似的内容（使用绝对定位和一个z-index值）并将密码框放在那里。

There are a variety of libraries you can use that will do the hard work for you (not that it's thathard, but still). If you're already using a library like jQuery, Prototype, YUI, Closure, or any of several others, you may find that there's a plug-in designed for use with that library (jQuery UIfor jQuery, for instance). If not, there are plenty of stand-alone implementations. Look for "light box" or "lightweight window" or "JavaScript dialog box", etc.
您可以使用多种库来为您完成繁重的工作（并不是说它那么难，但仍然如此）。如果您已经在使用像jQuery、Prototype、YUI、Closure或其他几个库中的任何一个库，您可能会发现有一个专为与该库一起使用而设计的插件（例如jQuery UIfor jQuery）。如果没有，有很多独立的实现。寻找“灯箱”或“轻量级窗口”或“JavaScript对话框”等。
Note that any of these will require a bit of a change to the logic of your code, since promptbrings the browser and your script to a screeching halt until the prompt is dismissed by the user, whereas this mechanism of flying an element over the top of the content is, by its nature, asynchronous.
请注意，其中任何一个都需要对您的代码逻辑进行一些更改，因为prompt会使浏览器和您的脚本停止运行，直到用户取消提示，而这种将元素飞过顶部的机制内容本质上是异步的。
