在asp.net中使用javascript中alert的三張方法
string str = "<script language=javascript>alert(驗證碼不正確！);</script>";
Page.RegisterStartupScript("提示", str);//第一種方法，2005下提示已過時，可以考慮第3、4種方法
Response.Write(str); //第二種方法，最簡單的方法
public void Alert(string msg)//第三種方法
{
this.ClientScript.RegisterStartupScript(this.GetType(), "alert", "<script language="javascript">alert(" msg ");</script>");
}
public void Alert(string name, string msg)//第四種方法
...{
this.ClientScript.RegisterStartupScript(this.GetType(), name, "<script language="javascript">alert(" msg ");</script>");
}
asp.net中的ALERT、Conform寫法
