- C# code
public class Class1 : System.Web.UI.Page{ public Class1() { } public void aa(string strMessage) { ClientScriptManager cs = Page.ClientScript; Type cstype = this.GetType(); string csstring = "PopupScript"; string cstext = "alert('" + strMessage + "');"; cs.RegisterStartupScript(cstype, csstring, cstext, true); }}如上边的代码，我想将alert("....")写到一个类中然后再某些页面需要探出提示窗口的时候直接调用，但是在执行的时候没有出现问题，只是不会出现么messagebox
我想请问一下是不是Page.ClientScript的问题，个位帮忙解答一下！
------解决方案--------------------------------------------------------
类a
public static void Alert(string str, Page page)
{
str = Regex.Replace(str,"['|\r|\n]*", "");
page.ClientScript.RegisterStartupScript(page.GetType(), "alert", string.Format("alert(\"{0}\")", str), true);
}
调用:
a.Alert("xxx", Page);
------解决方案--------------------------------------------------------
this.Page.RegisterStartupScript("alert", "<script language=javascript>alert('" + strMessage + "');</script>");
用这个 传一个page对象进去试试
我没用 只是猜想
