无法显示从jquery ajax调用返回的json数据

Question

can somebody please tell me, how can I display json data returning from the ajax call. I am new to this.

$.ajaxSetup({
cache: false,
timeout: 5000

});

//String.prototype.toJSON;

var the_object = {};


function concatObject(obj) {
    strArray = []; //new Array
    for (prop in obj) {
        strArray.push(prop + " value :" + obj[prop]);
    }
    return strArray.join();
}
//var ntid = "hhsh";
//document.writeln("httpRequest.responseText");

$(document).ready(function() {
    $("button").ajaxStart(function() {
        alert('Triggered ajaxStart handler.');
    });
    $("button").click(function() {
        $.ajax({
            type: "POST",
            dataType: 'JSON',
            //data: "{'ntid':'john'}",
            //contentType: "application/json; charset=utf-8",
            //processData: false,
            url: "Testing.aspx/SendMessage",
            error: function(XMLHttpRequest, textStatus, errorThrown) {
                alert(textStatus);
            },
            success: function(result, txtStatus, httpRequest) {
                alert(txtStatus);
            //$('#status').html(httpRequest.responseText);
                //the_object = result;
                $('#status').html(concatObject(result));
                //$('#status').html(the_object);
                //alert("hello" + concatObject(the_object));
                //document.writeln(concatObject(the_object));
            }
        });
        //alert(concatObject(the_object));
        //$('#status').html(concatObject(the_object));

    });
});

above is the js file. should i need to do something on asp file directly to display it. if yes, then how? please reply me soon. im stuck here and unable to display data here. Its only diplaying this line:

toJSON value :function (key) { return this.valueOf(); }

Answer 1

Your result is most likely rooted with a property named d. Try modifying your success to use result.d;

This is usually a security measure that has to do with exploits which target a JSON collection with single root parent.
