如何在asp.net中获取警报消息 [英] how to get alert message in asp.net

问题描述

嗨

我使用以下代码显示警报消息，但是我什么也没收到，请检查此

Hi

I used the following code to display alert message but i am not getting any thing Please check this

string strMsg = "Leave has been applied already between " + txtFromDate.Text.Trim() + " and " + txtToDate.Text.Trim() + "";
                        string script = "<script language=\"javascript\" type=\"text/javascript\">alert('" + strMsg + "');</script>";
                        Response.Write(script);

推荐答案

选中此.

check This .

Page.RegisterStartupScript("Key", "<script type='text/javascript'>window.onload = function(){alert('Please accept Terms and Conditions before submitting.');return false;}</script>");

将双引号排序:

Sort out your double quotes:

string script = "<script language="\""javascript\"

成为

string script = "<script language=\"javascript\"

修改为

modify as

string strMsg = "Leave has been applied already between " + txtFromDate.Text.Trim() + " and " + txtToDate.Text.Trim() + "";
                     string script = "<script language=\"javascript\" type=\"text/javascript\">alert('" + strMsg + "');</script>";
                     Response.Write(script);

注意:尝试显示不带回发的javascript警报消息

Note: Try to show alert message from javascript without postback
