创建新数组，其中带逗号的项目在数组中分成唯一项目 [英] Create new array in which items with commas are separated into unique items in the array

问题描述

我有一个数组，它使用 concat 组合多个数组的源。

I have an array that is combining the sources of multiple arrays using concat.

var tags = [].concat.apply([], [typeArr,genderArr,conditionArr]);

然后过滤任何

  tags = tags.filter(function(entry) { return entry.trim() != ''; });

然而，我意识到，由于数据的来源，有些项目是以字符串形式出现的用逗号，这样标签数组如下所示： [red，blue，green，yellow，orange，purple ，黑色]

However, I realized that, because of where the data comes from, some items are coming in as strings with commas, such that tags array looks like the following: ["red","blue","green,yellow,orange","purple,black"]

我如何拆分项目，使标签数组看起来像 [red， 蓝色， 绿色， 黄色， 橙色， 紫色， 黑] ？我在思考我在数组上循环然后使用split将这些重新插入到一个新数组中的东西？

How could I split the items so that the tags array looks like ["red","blue","green","yellow","orange","purple","black"]? I was thinking something where I loop over the array and then use split to reinsert these into a new array?

我正在尝试使用vanilla JavaScript

推荐答案

使用 .toString（） Array.join（） / code>也是如此）将数组转换为单个字符串，使用 Array.split（） 用逗号来获取单个项目的数组：

Use Array.join() by comma (or .toString() which does the same) to convert the array to a single string, the use Array.split() by comma to get an array of individual items:

var arr = ["red","blue","green,yellow,orange","purple,black"];

var result = arr.join(',').split(',');

console.log(result);
