Question

Trying to figure out how to convert how to covert 5 variables I have in JavaScript (strings) to a JSON for sending along to my ajax function

here is my ajax function, sill relatively new to this but I believe this should work .. but I need to convert all my strings to a JSON – don’t I?

I believe there are alternative ways of sending data without json, but this is the recommended way isn’t it?

                $.ajax({
                type: "POST",
                url: "MyService.aspx/SendEmail",
                data: "{}",
                contentType: "application/json; charset=utf-8",
                dataType: "json",
                success: function(msg) {
                    alert(msg.d);
                },
                error: function() {
                    alert('error');
                }

            });

I believe that at the service end I need to extract the JSON – I am using asp.net

Any ideas?

I suggest you to include in your project JSON2.js, that you can find at this link, and to use the JSON.stringify() function:

...
data: JSON.stringify({ yourVar: "value", var2: "value2" }),
...

if your web service return json data you can parse the result with the library:

success: function(json) { json = JSON.parse(json);
                          var o = json.d;
                          ... 
}

It can assure you that your input data will be sanitized from every illegal character.
