JSON(JavaScript Object Notation) 是一种轻量级的数据交换格式.
一、JSON字符串转换为JSON对象： eval（) 和 JSON.parse
eg- json字符串: var data = '{ "name": "dran", "sex": "man" }';
var obj = eval（"("+data+")"); 或者
var obj = JSON.parse(data)；
然后，就可以这样读取： alert(obj.name + obj.sex);
提示：为什么要 eval这里要添加 ("("+data+")");呢？
原因在于：eval本身的问题。 由于json是以”{}”的方式来开始以及结束的，在JS中，它会被当成一个语句块来处理，所以必须强制性的将它转换成一种表达式。
加上圆括号的目的是迫使eval函数在处理JavaScript代码的时候强制将括号内的表达式（expression）转化为对象，而不是作为语句（statement）来执行。举一个例子，例如对象字面量{}，如若不加外层的括号，那么eval会将大括号识别为JavaScript代码块的开始和结束标记，那么{}将会被认为是执行了一句空语句
二、JSON对象转换为JSON字符串 ： obj.toJSONString()或者全局方法JSON.stringify(obj) (obj代表json对象)
eg-json对象: var obj = { "name": "dran", "sex": "man" };
var jstring = JSON.stringify(obj) ;// 建议用这个
var jstring = obj.toJSONString(); //toJSONString()不是js原生的方法，需要引入相应的库或自己定义后才能用 (不习惯用)
然后，就可以这样读取： alert(jstring);
注意：
目前，Firefox、Opera、IE8以上版本也提供了本地JSON支持。其中，JSON解释器提供的函数有：JSON.parse、JSON.stringify。 对于那些并不提供本地JSON支持的浏览器可以引入脚本json2.js，来实现JSON转换功能。
在https://github.com/douglascrockford/JSON-js上获取到这个js，一般现在用json2.js。
在AJAX实现前后台数据交互的时候，通常使用JSON的数据格式，对于JSON来说，有严格的代码规范，一旦格式出问题，就无法显示出相应效果，同时还不在控制台报错
补充： ajax读取json数据拼接显示：
json文件：
{
"first":[
{"name":"张三","sex":"男","like":["吃饭","睡觉","打豆豆"]},
{"name":"李四","sex":"男"},
{"name":"王武","sex":"男"},
{"name":"李梅","sex":"女"},
],
"second":[
{"name":"上海大学","area":"上海"},
{"name":"武汉大学","area":"武汉"},
{"name":"北京大学","area":"北京"},
{"name":"山东大学","area":"山东"},
]
}html和ajax代码
1、用for循环
1 $.ajax({
2 url : "ceshi.json",
3 type : "POST",
4 dataType :"text", //浏览器把json文件当作文本文件 不然读取不出来 权宜之策就改成了text， 因为测试， json文件格式正确书写
5 success: function(data) {
6 var dataJson = eval（"("+data+")"); // 将json字符串数据解析成对象
7 var arr1 = dataJson.first;
8 var arr2 = dataJson.second;
9 //一栏显示 用for循环完成数组解析
10 for(var i = 0; i<arr1.length; i++){
11 for(var j = 0; j<arr2.length; j++){
12 var str='<div style="display:block">'+
13 '<div>姓名：'+arr1[i].name+' 性别：'+arr1[i].sex+'</div>'+
14 '<div>学校:'+arr2[j].name+'</div>'+
15 '<div>地点:'+arr2[j].area+'</div>'+
16 //'<div>喜好:'+arr1[i].like+'</div>'+ //全显示
17 //'<div>喜好:'+arr1[i].like[1]+'</div>'+ //单独设置
18 //'<div>喜好:'+arr1[i].like[0]+'</div>'+
19 '</div>';
20 }
21
22 $(".result").append(str);
23
24 }
25
26
27
28
29 //分层显示
30 //var str = "";
31 // var str1 = "";
32 // if (arr1 != null) {
33 // for (var i = 0; i < arr1.length; i++) { //这里面都是创建并赋值
34 // str += "<span>" + arr1[i].name + "</span><span>" + arr1[i].sex + "</span><br>";
35 // }
36 // $(".result").html(str);
37 // }
38 // if (arr2 != null) {
39 // for (var j = 0; j < arr2.length; j++) {
40 // str1 += "<span>" + arr2[j].name + "</span><span>" + arr2[j].area+ "</span><br>";
41 // }
42 // $(".result2").html(str1);
43 // }
44 },
45 error:function(data){
46 alert("error");
47 }
48 })
49 <div class="result">frist:</div>
50 <div class="result2">second:</div>View Code for
2、 each循环 使用$.each方法遍历返回的数据date,插入到class为 .result中
1 JSON:
2 [
3 {"name":"张三","sex":"男","like":["吃饭","睡觉","打豆豆"]},
4 {"name":"李四","sex":"男"},
5 {"name":"王武","sex":"男"},
6 {"name":"李梅","sex":"女"},
7 ]
8 $.ajax({
9 url : "ceshi.json",
10 type : "POST",
11 dataType :"text", //浏览器把json文件当作文本文件 不然读取不出来 权宜之策就改成了text， 因为测试， json文件格式正确书写
12 success: function(data) {
13 var dataJson = eval（"("+data+")"); // 将json字符串数据解析成对象
14
15 //each循环 使用$.each方法遍历返回的数据date,插入到class为 .result中 i 表示索引 item 信息值 对象
16 $.each(dataJson,function(i,item){
17 var str='<div style="display:block">'+
18 '<div>姓名：'+item.name+' 性别：'+item.sex+'</div>'+
19 '<div>like:'+item.like+'</div>'+
20 '</div>';
21 $(".result").append(str);
22 })
23
24
25 },
26 error:function(data){
27 alert("error");
28 }
29 })
30
31 <div class="result"></div>View Code each
PS:对于一般的js生成json对象，只需要将$.each()方法替换为for语句即可，其他不变
$.each()函数不同于JQuery对象的each()方法，它是一个全局函数， 第1个参数以一个数组或者对象， 第2个参数以一个回调函数作为。回调函数拥有两个参数：第1个为索引（0开始），第2个为对应变量或内容。
$(function(){
$('#send').click(function(){
$.ajax({
type: "GET",
url: "test.json",
data: {username:$(".username").val(), content:$(".content").val()},
dataType: "json",
success: function(data){
$('#Text').empty(); //清空Text里面的所有内容
var str = '';
$.each(data, function(i, comment){
str += '<div class="comment"><h6>' +comment['username']+ ':</h6><p class="para">' +comment['content']+ '</p></div>';
});
$('#Text').html(str);
}
});
});
});
JSON 数据使用方法:
//json对象：
var jsonObj= {
"name":" 张三",
"sex":"男",
"age":26,
};
使用： jsonObj.name= "张三"
jsonObj.age= "26"//json数组： []下标 从 0 开始
var jsonArr =[
{"name":"张三","sex":"男","like":["吃饭","睡觉","打豆豆"]},
{"name":"李四","sex":"男"},
{"name":"王武","sex":"男"},
]
使用： jsonArr[0].sex="男"
jsonArr[1].name="李四"//多个数组： []下标 从 0 开始
var options = {
"city" :[
{
"name":"上海",
"area":"普陀区",
"option":"真北路",
"correct":"1"
},
{
"name":"石家庄",
"area":"河北",
"option":"在北方",
"correct":"2"
}],
"world":[
{
"title":"美国",
"content":"好莱坞大片 科幻"
},
{
"title":"中国",
"content":"爱我中华，虽远必诛"
}
]
};
options.city[0].area="普陀区"
options.world[1].content="爱我中华，虽远必诛

或者创建script
