Ajax 调用未命中 C# 代码后面的 web 方法

Question

Good morning. Currently I'm having a problem having my ajax call go from the JQuery to C# code behind. After that's successful it should return the true value at the end of the function. I've tried removing the type and changing the web method to an HttpPost header which I can't do. Here's an example of the code.

Javascript

var jsonFormValues = JSON.stringify(formValues);
    $.ajax({
        type:POST,
        async: false,
        url: "RegistryOpt.aspx/SendOpt",
        data: { jsonFormValues: jsonFormValues },
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        success: function (result) {
            onWebMethodSucceeded();
        }
    });

C#

[WebMethod(EnableSession = true)]
public static bool SendOpt(string jsonFormValues)
{
    Debug.Assert(!string.IsNullOrEmpty(jsonFormValues));

    var fv = Json.Decode<FormValues>(jsonFormValues);

    fv.attestationItems = RegistryOpt.FormatAttestation(fv.attestation);

    var eb = new EmailBuilder(fv);

    return true;
}

I think the problem is that you are formatting to JSON only parameter value. Instead of var jsonFormValues = JSON.stringify(formValues); , you need to use JSON.stringify for parameter itself too:

    $.ajax({
        type:POST,
        async: false,
        url: "RegistryOpt.aspx/SendOpt",
        data: JSON.stringify({ jsonFormValues: formValues }),
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        success: function (result) {
            onWebMethodSucceeded();
        }
    });
