在JSP中，当添加信息成功后跳转回主页面并d出 *** 作成功提示框_IT百科

这样：

if((String)request.getAttribute("info")=="success"){%>

alert("添加活动成功！")

</script>

<%}%>

扩展资料：

注意事项

后台action/servlet执行后，返回处理结果（成功、失败、原因、状态等）信息。在前台jsp进行d窗显示，alert()

后台处理代码：（把要提示的数据放到session中。）

if(flag){

message="分类修改成功"

req.getSession().setAttribute("message",message)

resp.sendRedirect(req.getContextPath()+"/servlet/categoryListServlet")

}else{

message="分类修改失败"

req.getSession().setAttribute("message",message)

}

可以引用脚本语言实现；<br>在jsp页面加入<script language="javascript"><br>这样就可以使用javascript的三种与用户进行交互的对话框，如下所示：<br><br>1 alert("message") 显示含有给定消息的"JavaScript Alert"对话框. <br><br>2 confirm("message") 显示含有给定消息的"Confirm"对话框(有一个OK按钮和一个Cancel按钮).如果用户单击OK返回true,否则返回false. <br><br>3 prompt("message") 显示一个"prompt"对话框,要求用户根据显示消息给予相应输入. <br><br>4 open("URL","name") 打开一个新窗口,给予一个指定的名字. <br><br>5 close() 关闭当前窗口<br><br>希望能帮到你！

jsp中可以嵌入通用的js写的d出框提示，只要根据不同场景传不同参数就可以了。

参考代码如下：

<html>

<head>

<title>d出窗口(可拖动，背景灰色透明)</title>

<!--

/*FileName:AlertMsg.js

title:提示标题

content:提示的内容*/

document.write("<style type=\"text/css\">*{padding:0margin:0}.close{float:rightcursor:default}</style>")

function $(id){ return document.getElementById(id)}

function AlertMsg(title,content){

var msgw,msgh,msgbg,msgcolor,bordercolor,titlecolor,titlebg,con

con = "<form><table style='margin:10px 15px 15px 15pxborder:0'><tr><th style='border:0line-height:22pxpadding:3px 0vertical-align:topfont-weight:bold'>分类：</th><td style='border:0line-height:22pxpadding:3px 0vertical-align:topwidth:75%'><input type='text' name='typename' size='20'/></td></tr><tr><th></th><td style='border:0line-height:22pxpadding:3px 0vertical-align:topwidth:75%'><button style='line-height:normal' type='submit' onclick='return submitform()'>确定</button>　<button style='line-height:normal' type='reset'>取消</button></td></tr></table></form>"
