怎么用JS循环取到array里面的值啊
vararr=[{"a":"1","b":"2","c":"3"},{"a":"12","b":"22","c":"32"},{"a":"13","b":"23","c"...
var arr=[ {"a":"1","b":"2","c":"3"}, {"a":"12","b":"22","c":"32"},{"a":"13","b":"23","c":"33"}]

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])
}

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