回答（1）：

var arr=[ {"a":"1","b":"2","c":"3"}, {"a":"12","b":"22","c":"32"},{"a":"13","b":"23","c":"33"}]
for(x in arr){
	for(y in arr[x]){
		alert(y + ":" + arr[x][y])
	}		
}

回答（2）：

var arr=[ {"a":"1","b":"2","c":"3"}, {"a":"12","b":"22","c":"32"},{"a":"13","b":"23","c":"33"}];
for(var i=0;iconsole.log(arr[i])
}

输出：
Object {a: "1", b: "2", c: "3"}
Object {a: "12", b: "22", c: "32"}
Object {a: "13", b: "23", c: "33"}

接下来就好做了

arr[i].a会取出 1,12,13
b和c同理
