显示带有文本字段的警报框

问题描述

我是jquery新手.每当页面加载时，我想显示其中带有TextBox字段的Alert Box.像这样:

I am new to jquery. I want to show a Alert Box with TextBox field in it, whenever the page loads. Something like this:

Enter Your Username: //Title
___________________  //TextBox field (value will be stored in var for later use)

                OK   //Button

我知道

var username = "username";  //already entered message
alert(username);

如何实现上述警告框?我应该手动编码吗?
最好在jQuery中给出示例.我正在尝试为我的聊天应用程序执行此操作，其中需要用户名才能在聊天中显示.我进行了大量搜索，但找不到与asp.net和jquery相关的任何有用信息.

How to achieve the above Alert Box? should I manually code it?
Giving an example in jQuery is preferable. I am trying to do this for my chat application where username is required to show in the chat. I searched alot but couldn't find any useful related to asp.net and jquery.

推荐答案

Just use good old JavaScript:

var text = prompt("prompt", "textbox's intial text");
