Null value passed to servlets using jquery ajax
I am developing a sample application with jquery ajax.My Login.jsp has
<html>
<script>
$(document).ready(function() {
$("#dialog").dialog();
$("#LoginForm").submit(function()
{
var username=$("#username").val();
var password=$("#password").val();
var datastring='username '+username+ '&password '+password;
$.ajax({
url: 'Login',
type: "POST",
data: datastring,
/*error: function(){
alert("Data Error");
},*/
success: function (data){
window.open.href("success.jsp");
}
});
});
});
</script>
</head>
<body>
<div id="dialog" title="LoginDB">
<form id="LoginForm" method="post">
<fieldset>
<label>Username:</label>
<input type="text" id="username" value=""></input><br></br>
<label>Password:</label>
<input type="password" id="password" value=""></input><br></br>
<input type="submit" id="submit" class="submit" value="Log In" align="middle"></input>
</fieldset>
&开发者_高级运维lt;/form>
</div>
</body>
</html>
when I run the application I see that null value is passed in servlet where I check for credentials and if success the data is inserted and the user is redirected to success page.I know its a simple error but am not able to figure it out..
Can anyone point me out??Thanks:)
The querystring that is being generated is wrong.
Change var datastring='username '+username+ '&password '+password; to
var datastring='username='+username+ '&password='+password;
Better alternative is to use the jquery form serialize to get the post data.
Try this:
var postData =$("#LoginForm").serialize();
$.ajax({
url: 'Login',
type: "POST",
data: postData

加载中,请稍侯......
