<script type="text/javascript" src="../pagejs/jquery-2.1.4.min.js"></script>
<link rel="stylesheet" type="text/css" href="../pagecss/bootstrap.min.css"/>
<script type="text/javascript">
function showmsg(msgdata) {
$("#msginfo").hide();
$("#msginfo").html("<b>" + msgdata + "</b>");
$("#msginfo").show(1000);
}
$().ready(function() {
$("#login").click(function() {
var user = $("#inputEmail").val(); var pwd = $("#inputPassword").val(); if (user == "" || pwd == "") {
showmsg("please input email and password"); return;
}
$.post("login.do", {
email:user,
pwd:pwd
}, function(data, status){
if (data == "loginok") {
location.href = "welcome.jsp";
} else {
showmsg(data);
}
});
});
