The $.ajax of this method, inside the datatype: "JSON" set, if the server returns a JSON-formatted string, it is not necessary to call the Eval method to convert to a JSON object

$.ajax ({
Type: "Post",
URL: "ajax.asp tutorial X",

DataType: "JSON",
Success:function (data) {
alert (data.name);
var person = DATA.D;
For (var p in person) {
}

Example Three

function Btnclick1 () {
$.ajax ({
URL: "Json.ashx",
Type: "Post",
Data: {cmd: "Getinfo1"},
Beforesend:loading,
Success:function (data) {
Using the Eval function
var json = eval (data);
$ ("#dd"). empty ();

for (var i = 0; i < json.length; i++) {
$ ("#dd"). Append ("Alert (json[i].id + "name:" + json[i].name);
}
}

});
}
