本文实例讲述了C#实现的JS操作类。分享给大家供大家参考。具体如下：

这个C#类封装了常用的JS客户端代码操作，包括弹出对话框、返回上一页，通过JS转向，弹出警告框并转向等。

using System.Web; namespace DotNet.Utilities { /// <summary> /// 客户端脚本输出 /// </summary> public class JsHelper { /// <summary> /// 弹出信息,并跳转指定页面。 /// </summary> public static void AlertAndRedirect(string message, string toURL) { string js = "<script language=javascript>alert('{0}');window.location.replace('{1}')</script>"; HttpContext.Current.Response.Write(string.Format(js, message, toURL)); HttpContext.Current.Response.End(); } /// <summary> /// 弹出信息,并返回历史页面 /// </summary> public static void AlertAndGoHistory(string message, int value) { string js = @"<Script language='JavaScript'>alert('{0}');history.go({1});</Script>"; HttpContext.Current.Response.Write(string.Format(js, message, value)); HttpContext.Current.Response.End(); } /// <summary> /// 直接跳转到指定的页面 /// </summary> public static void Redirect(string toUrl) { string js = @"<script language=javascript>window.location.replace('{0}')</script>"; HttpContext.Current.Response.Write(string.Format(js, toUrl)); } /// <summary> /// 弹出信息 并指定到父窗口 /// </summary> public static void AlertAndParentUrl(string message, string toURL) { string js = "<script language=javascript>alert('{0}');window.top.location.replace('{1}')</script>"; HttpContext.Current.Response.Write(string.Format(js, message, toURL)); } /// <summary> /// 返回到父窗口 /// </summary> public static void ParentRedirect(string ToUrl) { string js = "<script language=javascript>window.top.location.replace('{0}')</script>"; HttpContext.Current.Response.Write(string.Format(js, ToUrl)); } /// <summary> /// 返回历史页面 /// </summary> public static void BackHistory(int value) { string js = @"<Script language='JavaScript'>history.go({0});</Script>"; HttpContext.Current.Response.Write(string.Format(js, value)); HttpContext.Current.Response.End(); } /// <summary> /// 弹出信息 /// </summary> public static void Alert(string message) { string js = "<script language=javascript>alert('{0}');</script>"; HttpContext.Current.Response.Write(string.Format(js, message)); } /// <summary> /// 注册脚本块 /// </summary> public static void RegisterScriptBlock(System.Web.UI.Page page, string _ScriptString) { page.ClientScript.RegisterStartupScript(page.GetType(), "scriptblock", "<script type='text/javascript'>" + _ScriptString + "</script>"); } } }

希望本文所述对大家的C#程序设计有所帮助。
