javascript - 将标识符放入数组内的对象

Question

假设我创建了这个数组:

var arr = [1, "ikanej", b={name:"Olsi", surname : "Angjellari"}]

有没有办法用标识符引用该数组的第三个元素？

像这样

arr.b.name  // this doesn't work

不是这样的

arr[2].name // this does but you need to keep track of index.
            // It would be easier to have an identifier

Answer 1

您应该创建一个对象而不是数组:

JS:

var arr = {0:1, 1:"ikanej", b:{name:"Olsi", surname : "Angjellari"}};

$('.body').append(arr.b.name);
