When I add this code part to my ASP.net project I got error says "Microsoft JScript runtime error: '$' is undefined". Since I'm using CDN for js files hope I dont need to js reference files to my project.
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script>
<script type="text/javascript" src="http://ajax.cdnjs.com/ajax/libs/json2/20110223/json2.js"></script>
<script type="text/javascript">
$("#btnCity").live("click", function () {
var city = {};
city.Name = "Mumbai";
city.Population = 2000;
$.ajax({
type: 'POST',
url: 'CS.aspx/GetCity',
data: "{city:" + JSON.stringify(city) + "}",
contentType: 'application/json; charset=utf-8',
dataType: 'json',
success: function (r) {
alert(r.d.Name);
alert(r.d.Population);
}
});
});
</script>
