Java乔晓松-ajax实现用户名和邮箱唯一验证实例(struts2框架和HIbernate)

ajax实现用户名和邮箱的唯一的验证
采用struts2+hibernate+ajax实现user用户注册时用户名和邮箱的唯一验证
index.jsp的源代码:
<%@ import="java.util.*" language="java" page="" pageencoding="UTF-8">
<%@ import="java.util.*" language="java" page="" pageencoding="UTF-8">
<%@ prefix="s" taglib="" uri="/struts-tags">
<%@ prefix="s" taglib="" uri="/struts-tags">
<%
 String path = request.getContextPath();
 String basePath = request.getScheme() + "://"
   + request.getServerName() + ":" + request.getServerPort()
   + path + "/";
%>
 
 
 
<%< div="">
 
 
 
 
 
 
 
 
<script type="text/javascript" src="${pageContext.request.contextPath }/js/util.js"></script>
<script type="text/javascript" src="${pageContext.request.contextPath }/js/reg.js"></script>

reg.js(验证)文件的源代码:
window.onload = function() {
 var name = $("adminName");
 var email = $("adminEmail");
 name.onblur = function() {
  changeblur("cname", "name", name);
 };
 email.onblur = function() {
  changeblur("cmail", "email", email);
 };
};
function changeblur(msg, type, btn) {
 var xhr = createXHR();
 xhr.onreadystatechange = function() {
  if (xhr.readyState == 4) {
   if (xhr.status == 200 || xhr.status == 304) {
    $(msg).innerHTML = xhr.responseText;
   }
  }
 };
 var url = "./csdn/AdminAction_check.action?time=" + new Date().getTime();
 xhr.open("POST", url, true);
 xhr.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
 var content = type + "=" + btn.value;
 xhr.send(content);
}
 
 
util.js(工具js)文件的源代码:
function $(id) {
 return document.getElementById(id);
}
function createXHR() {
 var xmlHttpRequest;
 var aVersion = [ "MSXML2.XMLHttp.5.0", "MSXML2.XMLHttp.4.0",
   "MSXML2.XMLHttp.3.0", "MSXML2.XMLHttp", "Microsoft.XMLHttp" ];
 try {
  xmlHttpRequest = new XMLHttpRequest();
 } catch (ex) {
  for ( var i = 0; i < aVersion.length; i++) {
   try {
    xmlHttpRequest = new ActiveXObject(aVersion[i]);
    return xmlHttpRequest;
   } catch (ex) {
    continue;
   }
  }
 }
 return xmlHttpRequest;
}
