下载JS文件引用到page中，如下代码：
<!-- Dependencies -->
<script src="/path/to/jquery.js" type="text/javascript"></script>
<script src="/path/to/jquery.ui.draggable.js" type="text/javascript"></script>
<!-- Core files -->
<script src="/path/to/jquery.alerts.js" type="text/javascript"></script>
<link href="/path/to/jquery.alerts.css" rel="stylesheet" type="text/css" media="screen" />
注意其中draggable是用来实现拖拉的，如不需要这个功能不就不用引用。在目前最近的Jquery1.42下应用引用：
<script src="Scripts/jquery-1.4.2.min.js" type="text/javascript"></script>
<script src="Scripts/jquery-ui-1.8.5.custom.min.js" type="text/javascript"></script>
<script src="Scripts/jquery.alerts.js" type="text/javascript"></script>
<link href="Content/Style/jquery.alerts.css" rel="stylesheet" type="text/css" />
主要方法有：
jAlert(message, [title, callback]) 创建一个alert
jConfirm(message, [title, callback]) 创建一个确认allert,支持callback
jPrompt(message, [value, title, callback]) 创建一个提示框让用户输入值，支持callback如果你有提供
可以参下面的示例Code:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Defualt.aspx.cs" Inherits="WebApplication6.Defualt" %>

<link href="Content/Style/jquery.alerts.css" rel="stylesheet" type="text/css" />
<script type="text/javascript">
$(document).ready(function () {
$("#btnAlert").click(function ()
{ jAlert('Pushed the alert button', 'Alert Dialog'); });
$("#btnPrompt").click(function () {
jPrompt('Type some value:', '', 'Prompt Dialog', function (typedValue) {
if (typedValue) {
jAlert('You typed the following ' + typedValue);
}
});
});
});
</script>

<input type="button" value="Alert Me" id="btnAlert" />
<input type="button" value="Prompt Me" id="btnPrompt" />
