Ajax with asp.net aspx returns Undefined
I'm facing the following issue: Whenever I click on the button , the alert shows undefined .
Web method:
[WebMethod]
public static string getTest()
{
return "testing success";
}
Ajax script
<script type="text/javascript">
function getTest() {
$.ajax({
type: "POST",
url: "main.aspx/getTest",
data: "{}",
datatype: "json",
contenttype: "/application/json; charset=utf-8",
success: function (msg) {
alert(msg.d);
},
error: function (data) {
}
});
}
</script>
datatype should be dataType and contenttype should be contentType . Also remove / from start of "/application/json; charset=utf-8"
$.ajax({
type: "POST",
url: "main.aspx/getTest",
data: "{}",
dataType: "json",
contentType: "application/json; charset=utf-8",
success: function (msg) {
alert(msg.d);
},
error: function (data) {
}
});
Remove these from your ajax call
datatype: "json",
contenttype: "/application/json; charset=utf-8",
