使用这种类似数组的对象可以获取每个属性的索引,但是在记录该对象时无法输出结果。我在这里做错了什么?
// Array-like object
var pickedCards = { 0: 'a', 1: 'b', 2: 'c' };
Object.getOwnPropertyNames(pickedCards).forEach(function(val) {
val++;
return pickedCards[val];
});
console.log(pickedCards);
最佳答案
尝试:
var pickedCards = { 0: 'a', 1: 'b', 2: 'c' }, pickedCardsChanges = {};
for(var card in pickedCards){
pickedCardsChanges[+card + 1] = pickedCards[card]
}
document.write(JSON.stringify(pickedCardsChanges))
