jquery - ASP CLassic JSON 标头问题

Question

任何想法为什么这会为我的 jquery ajax 调用大惊小怪。

Sub SetJsonHeader()
    Response.AddHeader "Content-Type", "application/json"
End Sub

something = Request.Form( "formLabel" )
SetJsonHeader()
Response.Write( "{ something: """ & something & """ }" )

response.write 正在返回正确的字符串 { something: "blabla" } 但是当我用我的 javascript 调用它时它会报告一个错误：

    $.ajax({
        dataType: "json",
        url: "includes/Process.asp",
        method: "POST",
        data: {
            process: "notrelevant",
            formLabel: something
        },
        success: function (data) {
            alert(data);
            $(obj).replaceWith(data.casName);
        },
        error: function (a, b, c) {
            alert(a.responseText + "\n" + b + "\n" + c);

            // alerts                 
            //     { something: "blabla" }
            //     parse error
            //     syntax error invalid character
        }
    });
