JavaScript Json数组的简单使用

1 var json = {"data":[]};
2 for(var i = 0; i < 4; ++i){
3     var newjson = {};
4     newjson["name"] = "白菜"+i;
5     newjson["age"]  = 100+i;
6     newjson["type"] = "蔬菜"; 
7     json.data.push(newjson);
8 }
9 console.log(json);

var str = ‘{"data":[{"leg":"6条腿", "name":"小昆虫"},{"leg":"4条腿", "name":"小白菜"},{"leg":"8条腿", "name":"小章鱼"}]}‘;
var json1 = JSON.parse(str);
for(var i = 0; i < json1.data.length; ++i){
    console.log(json1.data[i].name+" "+json1.data[i].leg);
}
