Thus, I thought to share a sample code with you.
Important code segments to take note.
jQuery.support.cors = true: Force cross site scripting (XSS). Importantly, to work in internet explorer
jQuery.parseJSON(result): A well-formed JSON string is turned to a javascript object.
index.html page is as follows:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html>
<title>Sample jQuery Web Page</title>
<head>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
<script type="text/javascript">
Login = function() {
var resultDiv = $("#resultDiv");
jQuery.support.cors = true; //force cross site scripting - XSS
$.ajax({
url: "http://xyz.abc.com/user/login",
type: "POST",
data: { username: $("#username").val(), password: $("#password").val(), callback: "?" },
dataType: "text",
success: function (result) {
alert(result);
var res = jQuery.parseJSON(result);
var status= res.status;
alert(status);
switch (status) {
case 0:
alert("sessionId: " + res.sessionId);
alert("My profileId: "+ res.profileId);
resultDiv.html(result);
break;
default: //e.g. at invalide username, status=2
resultDiv.html(result);
}
},
error: function (xhr, ajaxOptions, thrownError) {
alert(xhr.status);
alert(thrownError);
}
});
};
</script>
</head>
<body>
<h1>Sample jQuery Web Page - Login</h1>
<form>
<label>Username</label>
<input name="Username" type="text" id="username" /> <br/><br/>
<label>Password</label>
<input name="Password" type="password" id = "password" />
<input name="Submit" type="button" id="submit" onclick="Login()" value="Submit" />
</form>
<div id="resultDiv"></div>
</body>
