C#后台输出JS代码我们通常是
Response.Write("<script>js代码</script>");
这样写非常不方便,因此去年10月份的时候特意写了一个封装类,共享在CSDN上,博文地址为http://blog.csdn.net/wenjie315130552/article/details/6934777
code:

调用:
样式一(返回上一个页面):
Alart.ShowAlart(System.Web.HttpContext.Current, "密码与确认密码不一致", Alart.AlartState.Back, "");
样式二(在本窗口打开):
asp.net mvc:
Alart.ShowAlart(System.Web.HttpContext.Current, "操作成功", Alart.AlartState.OpenInThisWindow, Url.RouteUrl(new { controller = "ControllerName", action = "ActionName"}));
关于如何使用Url.RouteUrl(object routeValues)请参照wtq的博文使用Url.Routeurl获取url值。
asp.net:
Alart.ShowAlart(System.Web.HttpContext.Current, "操作成功", Alart.AlartState.OpenInThisWindow,"PageName"));
在asp.net中 尽量用 ClientScript.RegisterStartup() 或者 clientScript.RegisterBlock 类似的这样方法,因为Response.Write()直接输出在页面上,会导致页面变形。
