从javascript中的对象数组中删除重复项

问题描述

我有一个对象包含一个对象数组。

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"});

我想知道从数组中删除重复对象的最佳方法是什么？所以例如，事情会变成...

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"}

提前感谢

推荐答案

我们来看看...原始的一个是：

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

var obj = {};

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

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

好的，我认为应该这样做。查看它，Travis。

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