Ajax return multiple values

问题

I'm trying to return multiple values as shown below but one value is only returning on success.

This is what I'm trying to do :

<script type="text/javascript">
        $(document).ready(function () {
                $("#getdetails").click(function () {
                $.ajax({
                    type: "POST",
                    url: "Default.aspx/Gettext",
                    data: JSON.stringify({ SampleText: $('#sampletext').val(), FontType: $('#fonttype').val()}),
                    contentType: "application/json; charset=utf-8",
                    dataType: "json",
                    success: function (msg) {
                        $("#Result").text(msg.d);
                    }
                });

        $("#FontLists").change(function () {
            $('#fonttype').val($('#FontLists option:selected').text());
        });
    });
</Script>

HTML:

Enter Text :<input id="sampletext" type="text" />
<select id="FontLists">
    <option value="Aharoni">Aharoni</option>
    <option value="Algerian">Algerian</option>
    <option value="Andalus">Andalus</option>
</select>
<input id="fonttype" type="hidden" />

Codebehind:

<WebMethod()> _
<ScriptMethod(ResponseFormat:=ResponseFormat.Json)>
Public Shared Function Gettext(ByVal SampleText As String, ByVal FontType As String) As String
    Return SampleText
    Return FontType
End Function

You could design a class with 2 properties and then have your WebMethod return an instance of this class (sorry if I made some typos, my VB.NET skills are rusty).

Public Class MyModel
    Public Property SampleText as String
    Public Property FontType as FontType
End Class

and then adapt your method to return this model:

<WebMethod()> _
<ScriptMethod(ResponseFormat:=ResponseFormat.Json)>
Public Shared Function Gettext(ByVal SampleText As String, ByVal FontType As String) As MyModel
    Dim model = New MyModel()
    model.SampleText = SampleText
    model.FontType = FontType
    Return model
End Function

and on the client you could access the 2 properties using their names:

success: function (msg) {
    alert(msg.d.SampleText);
    alert(msg.d.FontType);
}
