无法显示从jquery ajax调用返回的json数据

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

有人可以告诉我，如何显示从ajax调用返回的json数据。我是新来的。

$.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. i m stuck here and unable to display data here. Its only diplaying this line:

上面是js文件。我应该直接在asp文件上做一些事情来显示它。如果是，那怎么样？请尽快回复我我被困在这里，无法在这里显示数据。它只是在铺设这条线：

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

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

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

您的结果很可能是以名为d的属性为根。尝试修改您的成功以使用result.d;

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

这通常是一种安全措施，它与针对具有单根父级的JSON集合的漏洞利用有关。
