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。
