在Ember数组中，如何通过索引值访问对象？ Ember Js

Question

For an ember array you can simply do this:

array.get('firstObject');

to get the first object in array.

or this:

array.get('lastObject');

to get last object in array.

How do I get something by its index? similar to how it works in an ordinary javascript array:

array[index];

Answer 1

Looking at the documentation, you could just do var myObject = array.objectAt(someIndex); , and that will return the object at that specific index. You can check the documentation here.

Answer 2

array.get(index)

actually works. index can be either an integer or a string.

It also works for array-properties, ie.

this.get('myArray.1')

will return the second element in the myArray property.
