Question

我无法从数组中删除重复的对象

例子:

var list = [{place:"AAA",name:"Me"}, {place:"BBB",name:"You"}, {place:"AAA",name:"Him"}];

在这个例子中我有 3 个对象，我想删除具有重复位置的对象

Answer 1

以防万一有人想知道:underscore.js 解决方案:

var list = [{place:"AAA",name:"Me"}, {place:"BBB",name:"You"}, {place:"AAA",name:"Him"}];

_.uniq(list, function(item, key, a) { 
    return item.place;
})
