Json对象和字符串互相转换 数据拼接 JSON使用方式
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
![](https://images.cnblogs.com/OutliningIndicators/ContractedBlock.gif)
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 // $(".result2").html(str1); 43 // } 44 }, 45 error:function(data){ 46 alert("error"); 47 } 48 }) 49 <div class="result">frist:</div> 50 <div class="result2">second:</div>
2、 each循环 使用$.each方法遍历返回的数据date,插入到class为 .result中
![](https://images.cnblogs.com/OutliningIndicators/ContractedBlock.gif)
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 $(".result").append(str); 22 }) 23 24 25 }, 26 error:function(data){ 27 alert("error"); 28 } 29 }) 30 31 <div class="result"></div>
PS:对于一般的js生成json对象,只需要将$.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

其他 ,如果从后台读取的json 年份:{"year":116}, 如果想要显示正常的年份 可以用 1900+116 =2016 从1900算 + 返回的 = 现在的年份(其他方法更好,)
Jsonp::或者创建script
写了这么多, 希望对你有帮助,如有失误 一起讨论,一起进步!! ☺
