我在jsp中有以下页面。
该页面的代码如下：
<HTML>
<HEAD>
<META http-equiv=Content-Language content=en-us>
<META http-equiv=Content-Type content="text/html; charset=windows-1252">
<style TYPE="text/css">
<!-- BODY { font-family:arial,helvetica; margin-left:5; margin-top:0}
A { color:#FF5500; text-decoration:underline}
A:hover,A:active { color:#0055FF; text-decoration:underline}
-->
</style>
<Script Language="JavaScript">
<!--
function inStrGrp(src,reg)
{
var regex=new RegExp("[" + reg + "]","i");
return regex.test(src);
}
function check()
{
var uname=document.scan.elements[0].value
var bError=false
if (uname.length==0)
{
window.alert("Name is required.\n")
return false
}
if (uname.indexOf("\\")>=0)
bError=true
if (inStrGrp(uname,'/.:*?"<>| '))
bError=true
if (bError)
{
window.alert('User name can not contain the following characters:\n \\/. :*?"<>|\n')
return false
}
else
return true
}
-->
</Script>

当我单击Enroill按钮时，我想显示一个带有图像源标签的弹出窗口，如下所示。
如何在Jsp上执行此操作？任何建议都会有很大帮助。
