javascript和jquery分别实现用户登录验证

/*jquery实现
$(document).ready(function(){
$("#account").blur(function(event) {
$.ajax({
type:"GET",
url:"checkAccount.php?account="+$("#account").val(),
dataTypes:"text",
success:function(msg){
$("#accountStatus").html(msg);
},
error:function(jqXHR) {
alert("账号发生错误！")
},
});
});

$("#password").blur(function(event) {
$.ajax({
type:"GET",
url:"checkPassword.php?",
dataTypes:"text",
data:"account="+$("#account").val()+"&password="+$("#password").val(),
success:function(msg){
$("#passwordStatus").html(msg);
},
error:function(jqXHR) {
alert("密码查询发生错误！")
},
});
});
}); */

//javascript实现
function checkAccount(){
var xmlhttp;
var name = document.getElementById("account").value;
if (window.XMLHttpRequest)
xmlhttp=new XMLHttpRequest();
else
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");

xmlhttp.open("GET","checkAccount.php?account="+name,true);
xmlhttp.send();

xmlhttp.onreadystatechange=function(){
if (xmlhttp.readyState==4 && xmlhttp.status==200)
document.getElementById("accountStatus").innerHTML=xmlhttp.responseText;
}
}

function checkPassword(){
var xmlhttp;
var name = document.getElementById("account").value;
var pw = document.getElementById("password").value;
if (window.XMLHttpRequest)
xmlhttp=new XMLHttpRequest();
else
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");

xmlhttp.open("GET","checkPassword.php?account="+name+"&password="+pw,true);
xmlhttp.send();

xmlhttp.onreadystatechange=function(){
if (xmlhttp.readyState==4 && xmlhttp.status==200)
document.getElementById("passwordStatus").innerHTML=xmlhttp.responseText;
}
}
