推荐答案
你在这里遇到的问题是你只是推动这个名字。更重要的是，您将面临一个问题，即您要查找的内容是一个复杂的类型，因此您将不得不推出自己的实现。幸运的是，这是一件非常简单的事情。首先，你只需要添加你自己的indexOf版本（这样就可以了）：
The problem you have here is that you are just pushing the name. More importantly, you are going to face an issue where what you are trying to find is a complex type so you are going to have to roll your own implementation. Fortunately, that's a pretty trivial thing to do. First of all, you would simply add your own version of indexOf (something like this will do):
Array.prototype.complexIndexOf = function(type) {
for (var x = 0; x < this.length; x++) {
if (this[x].id === type.id && this[x].name === type.name)
return i;
}
return -1;
}使用此原型，您只需将for循环中的条件更改为：
With this prototype in place, you simply change the condition in your for loop to:
if (t.complexIndexOf(array[x]))t.push(array);
