  //基本上，Json返回的要么是對(duì)象，要么是數(shù)組，如果單純返回一個(gè)字符串，那么就沒(méi)有必要用Json了，因此
  //Json基本就下面這些可，不過(guò)要注意雙引號(hào)
  var str0 = "{employees:'測(cè)試'}";
  var obj0 = eval("(" + str0 + ")");
  alert(obj0.employees);   //輸出測(cè)試

  var str = "{name:'張三',Age:21}";
  var obj = eval("(" + str + ")");
  document.write(obj.name + obj.Age); //輸出 張三21
  alert(obj.name);

  //別看下面那段Json長(zhǎng)，其實(shí)是一個(gè)對(duì)象，屬性employees的值是一個(gè)對(duì)象數(shù)組。和上面的相比，只是name:張三 中的"張三"字符串 變成了對(duì)象數(shù)組而已
  var str2 = '{ "employees" : [' + '{ "firstName":"Bill" , "lastName":"Gates" },' + '{ "firstName":"George" , "lastName":"Bush" },' + '{ "firstName":"Thomas" , "lastName":"Carter" } ]}';
  var obj2 = eval("(" + str2 + ")");
  alert(obj2.employees[0].firstName);  //彈出 Bill

  var str3 = "[1,2,3,4,5,6]";    //json 數(shù)組

Json與JavaScript對(duì)象轉(zhuǎn)換

　　JSON轉(zhuǎn)javascript對(duì)象

//Json轉(zhuǎn)對(duì)象1
function JsonToObject(str) {
 return eval("(" + str + ")");
}

//Json轉(zhuǎn)對(duì)象2 
function strToJson(str){
 var json = (new Function("return " + str))();
 return json;
}

//Json轉(zhuǎn)對(duì)象3 jQuery工具函數(shù)
$.parseJSON()

　　javascript對(duì)象轉(zhuǎn)JSON

//javascript對(duì)象轉(zhuǎn)Json
function ObjectToJson(o) {
 var arr = [];
 var fmt = function(s) {
  if (typeof s == 'object' && s != null) return json2str(s);
  return /^(string|number)$/.test(typeof s) ? "'" + s + "'" : s;
 }
 for (var i in o) arr.push("'" + i + "':" + fmt(o[i]));
 return '{' + arr.join(',') + '}';
}
