脚本宝典收集整理的这篇文章主要介绍了ASP.NET中常用输出JS脚本的类实例，脚本宝典觉得挺不错的，现在分享给大家，也给大家做个参考。
本文实例讲述了ASP.NET中常用输出JS脚本的类，针对过去输出js脚本的类进行了一定的改进。在项目开发中非常具有实用价值。分享给大家供大家参考。具体如下：
很多时候在ASP.NET中我们经常需要输出一些JS脚本，比如弹出一个警告窗口，返回到历史页面等JS功能，我看到网上流传得比较广的是马先光写的一个JScript类，这个类基本将经常用到的JS脚本包含了，非常方便，唯一的不足是作者采用的Response.WrITe(string msg)的办法，这样造成输出的js脚本在<htML></html>标签之外，破坏了原有XHTML的结构，所以本人在满足原功能的情况下，对JScript类做了进一步的改善，这个改善采用了重载的办法，增加了一个System.Web.UI.Page类的实例作为参数，不会影响原来的程序代码。
整个程序的代码如下：
/// <summary>
/// 一些常用的Js调用
/// 添加新版说明：由于旧版普遍采用Response.Write(string msg)的方式输出js脚本，这种
/// 方式输出的js脚本会在html元素的&lt;html></html>标签之外，破坏了整个xhtml的结构,
/// 而新版本则采用ClientScript.RegisterStartupScript(string msg)的方式输出，不会改变xhtml的结构,
/// 不会影响执行效果。
/// 为了向下兼容，所以新版本采用了重载的方式，新版本中要求一个System.Web.UI.Page类的实例。
/// 创建者：马先光
/// 新版作者：周公
/// 修改版发布网址：http://blog.csdn.net/zhoufoxcn
/// </summary>
