object类型转换为Array类型

var obj = {a: 1, b: 2, c: 3}; // .... 
var arr = []; 
for(var key in obj){ if(!obj.hasOwnProperty(key)){continue;}var item = {}; item[key] = obj[key]; arr.push(item); 
} 
console.log(arr); // [{a: 1}, {b: 2}, {c: 3}]

// 将Object的属性输出成Array
function objOfPropertyToArr(object) {var arr = [];var i = 0;for (var item in object) {arr[i] = item;i++;}return arr;
}// 将Object的属性值输出成Array
function objOfValueToArr(object) {var arr = [];var i = 0;for (var item in object) {arr[i] = object[item];i++;}return arr;
}/* 
* 测试
*/
var obj = {name: "oschina",age: "18"
}
objOfPropertyToArr(obj); // 输出["name", "age"]
objOfValueToArr(obj); // 输出["oschina", "18"]
