Asp.net中用来代替Response.Write("<script>alert('错误信息');</script>");
如果直接在页面中使用Response.Write("<script>alert('错误信息');</script>"); 点击确定以后,可能会造成页面“错位”;
把代码封装到一个类中(就叫PageHelper.cs吧),在其他页面也可以方便的调用;
例如在其他页面调用:Page.Alert(this,"错语信息"); 效果和上面的代码是一样的,要说不同点吧?就是这个写法比上面的完美好多。
调用的时候也可以有第二个参数,即转跳地址: Page.Alert(this,"警告提示~","~/Default.aspx");
