How can i pass NULL value in ajax jquery call?

Is there any way to handle null value when doing Ajax Call?

 $.ajax({
            type: "POST",
            url: "Login.aspx/SaveFacebookAutoSignUp",
            data: "{ 'Name':'" + rows[0].name + "', 'EmailId': '" + rows[0].email + "'}",
            contentType: "application/json; charset=utf-8",
            dataType: "json",
            success: function (msg) {
                alert("You have successfully sign in.");

            }
        });

This is saving "null" value in my DB for EmailId when it is not fetch from other page?

I want to save "NULL" (DB default NULL allow) in DB when it is not having any value?

What is the way to do so?

You can use undefined instead of null, as in the following example:

data: {
  valueTrue : true,
  valueFalse: false,
  valueNull : undefined
}

Pass in the value null NOT surrounded by quotes.

{
    "id": "1234",
    "nullableValue": null
}

I'd suggest not composing your json string manually, create an object then use a function call to convert it to json. In some cases you can just pass the object to the ajax call.
