ลองดูตัวนี้ครับ
Code (jQuery)
<html>
<head>
<script src="http://code.jquery.com/jquery-latest.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$("#btn1").click(function(){
$.ajax({
url: "WebServiceClient.php" ,
type: "POST",
data: 'keyword=' +$("#txtCountryCode").val()
})
.success(function(result) {
$("#div1").empty();
var obj = jQuery.parseJSON(result);
$.each(obj, function(key, val) {
$("#div1").append('<hr />');
$("#div1").append('[' + key + '] ' + 'CustomerID=' + val["CustomerID"] +'<br />');
$("#div1").append('[' + key + '] ' + 'Name=' + val["Name"] +'<br />');
$("#div1").append('[' + key + '] ' + 'Email=' + val["Email"] +'<br />');
$("#div1").append('[' + key + '] ' + 'CountryCode=' + val["CountryCode"] +'<br />');
$("#div1").append('[' + key + '] ' + 'Budget=' + val["Budget"] +'<br />');
$("#div1").append('[' + key + '] ' + 'Used=' + val["Used"] +'<br />');
});
});
});
});
</script>
</head>
<body>
Search Customer (CountryCode)
<input type="text" id="txtCountryCode">
<input type="button" id="btn1" value="Search">
<div id="div1"></div>
</body>
</html>

จริงๆ ไม่ต้อง each ก็ได้นะ
ใช้ Obj.Department , Obj.username , Obj.password แทนแต่ไม่ควรจะ return password นะ
