遍历json对象数组
1.
传统数组遍历
var data=[{"name":"zhangsan","age":12},{"name":"lisi","age":22}];
for(var i=0;i<data.length;i++)
{
alert(data[i].name+"--"+data[i].age);
}
2.key/value map方式遍历 key-->索引 value-->Object
var data=[{"name":"zhangsan","age":12},{"name":"lisi","age":22}];
for(var key in data)
{
alert(data[key].name+"--"+data[key].age);
}
3.$.each方式 不常用
name -->索引 value-->Object
var data=[{"name":"zhangsan","age":12},{"name":"lisi","age":22}];
$.each(data,function(name,value){
alert(name+":"+value.name+","+value.age);
})
遍历json对象(没有什么实际意义 都是data.name data.age直接引用)
var data={"name":"zhangdan","age":22};
for(var key in data)
{
alert(data[key]);
}
