Emberjs中的本机数组不支持深层复制吗? [英] Native Array in Emberjs does not support deep copy?

问题描述

Emberjs中的本机数组不支持深层复制吗?我看到它只是在copy方法中返回切片的数组.是虫子吗?

Native Array in Emberjs does not support deep copy? I saw it just returning sliced array in the copy method. Is it a bug?

推荐答案

当前，这是对Ember的改进，由@adamjmurray报道:

Currently, that's an improvement going on Ember, reported by @adamjmurray: https://github.com/emberjs/ember.js/issues/588

还有一个实现它的命题.您可以像这样使用它:

There's also a proposition to implement it. You can use it like this:

var NativeArray = Ember.Mixin.create(Ember.NativeArray, {
    copy: function(deep) {
        if (deep) {
            return this.map(function(item){ return Ember.copy(item, true) });
        } else {
            return this.slice();
        }
    }
});

NativeArray.apply(Array.prototype);
