从 JS 数组中删除重复值 [英] Remove duplicate values from JS array

问题描述

我有一个非常简单的 JavaScript 数组，它可能包含也可能不包含重复项.

I have a very simple JavaScript array that may or may not contain duplicates.

var names = ["Mike","Matt","Nancy","Adam","Jenny","Nancy","Carl"];

我需要删除重复项并将唯一值放入新数组中.

I need to remove the duplicates and put the unique values in a new array.

我可以指出我尝试过的所有代码，但我认为它没有用，因为它们不起作用.我也接受 jQuery 解决方案.

I could point to all the codes that I've tried but I think it's useless because they don't work. I accept jQuery solutions too.

• 获取数组中的所有非唯一值(即:重复/多次出现)

推荐答案

使用 jQuery 又快又脏:

Quick and dirty using jQuery:

var names = ["Mike","Matt","Nancy","Adam","Jenny","Nancy","Carl"];
var uniqueNames = [];
$.each(names, function(i, el){
    if($.inArray(el, uniqueNames) === -1) uniqueNames.push(el);
});
