jQuery Ajax vs Classic ASP returning data

Help would be appreciated.

In My ASP page I am returning this [{'id': '123'}]. If you view the source then that is all you will see on the page nothing else. So makes sense that when I do a get that I would be able to get the id.

My Code (which I know works because I use it to do a get on flat files containing the same data. All I want to do now is create the data on the fly):

    $.ajax({      
        type: "GET",      
        url: "http://localhost/GetCustNewID.asp?callback=?",      
        async: false,      
        dataType: "jsonp",  
        success: function(data){     
            $(data).each(function(){
                alert(this.id)
            });开发者_如何转开发

        },
        error:function(x, e){
            if (x.status === 0){
                alert("You are offline.");
            }
            else if(x.status === 404){
                alert("404 file not found error");
            }
            else if(x.status === 500){
                alert("500 internal server error");
            }
            else if(e === 'parsererror'){
                alert("200 but can't parse json response");
            }
            else if(e === 'timeout'){
                alert("Request timed out.");
            }
            else {
                alert("Unknown AJAX error");
            }
        }

    });

I get a "200 but can't parse json response" returned. Is there something I am missing?

Thank you.

You are returning (invalid) JSON, but your JS is looking for JSON-P.

A JSON-P resource would be:

Content-Type: application/javascript

value_of_callback_query_string_value([{"id": "123"}]);

As opposed to a JSON response:

Content-Type: application/json

[{"id": "123"}]

Note that in JSON, strings are delimited with double quotes. You should make use of JSON Lint to test your output, and use a library (some are listed near the end of the JSON homepage) instead of trying to craft JSON by hand.

Seems like you should be using "json" instead of "jsonp".
