从JavaScript对象的数组删除重复 [英] Remove duplicates from an array of objects in javascript

问题描述

我有一个包含对象数组的对象。

I have an object that contains an array of objects.

things = new Object();

things.thing = new Array();

things.thing.push({place:"here",name:"stuff"});
things.thing.push({place:"there",name:"morestuff"});
things.thing.push({place:"there",name:"morestuff"});

我想知道什么是从一个数组中删除重复对象的最佳方法。因此，例如，things.thing将变得...

I'm wondering what is the best method to remove duplicate objects from an array. So for example, things.thing would become...

{place:"here",name:"stuff"},
{place:"there",name:"morestuff"}

在此先感谢

推荐答案

让我们来看看......一个原始的一种是：

Let's see ... a primitive one would be:

var arr = {};

for ( var i=0, len=things.thing.length; i < len; i++ )
    arr[things.thing[i]['place']] = things.thing[i];

things.thing = new Array();
for ( var key in arr )
    things.thing.push(arr[key]);

好吧，我认为应该做的伎俩。检查出来，特拉维斯。

Ok, I think that should do the trick. Check it out, Travis.

修改结果
编辑code正确引用地方（原 ID ）属性。
