请问在以下，下面这个json的表达式应该怎么写好了

Question

请问一下在android里面就是下面这个jsno 先是统计所有里面的formTemp里面的form_name 有多少内容不是为空的数据 form_value为内容，每次json formTemp的数据是变化的比如果这次可能有姓名，下次就可以能没有姓名，然后根据统计的数据显示整个json的数据，如姓名有三个人填写了，就只显示填写了姓名的人，请问这个表达式怎么写了

Answer 1

JSON语法规则：
数据在名称/值对中；
数据由逗号分隔；
大括号保存对象；
中括号保存数组
1、访问对象值：

var myObj,x;
myObj = {"name":"runoob","alexa":10000,"site":null};
x = myObj.name; //使用点号（.）来访问对象的值
x = myObj["name"]; //使用中括号（[]）来访问对象的值
2、使用for-in 来循环对象的属性：

var myObj = { "name":"runoob", "alexa":10000, "site":null }; for (x in myObj) { document.getElementById("demo").innerHTML += x + "<br>"; }

3、for-in循环对象的属性时，使用中括号（[]）来访问属性的值：

var myObj = { "name":"runoob", "alexa":10000, "site":null }; for (x in myObj) { document.getElementById("demo").innerHTML += myObj[x] + "<br>"; }

4、修改 JSON 对象的值：

myObj.sites.site1 = "www.google.com";
5、删除 JSON 对象的属性：

delete myObj.sites.site1;
5、使用索引值来访问数组：

var myObj, x; myObj = {"name":"网站","num":3, "sites":[ "Google", "Runoob", "Taobao" ] } x = myObj.sites[0]; document.getElementById("demo").innerHTML = x;

6、使用for-in 来访问数组：

var myObj, i, x = ""; myObj = { "name":"网站", "num":3, "sites":[ "Google", "Runoob", "Taobao" ] }; for (i in myObj.sites) { x += myObj.sites[i] + "<br>"; } document.getElementById("demo").innerHTML = x;
