uni-app：js二维数组与对象数组之间的转换

一、二维数组整理成对象数组 

效果

[

        ["前绿箭","DI10","RO1"],

        ["前红叉","DI2","RO2"],

        ["后绿箭","DI12","RO3"],

        ["后红叉","DI4","RO6"]

] 

整理为

[

        {"DI":"DI10","RO":"RO1","name":"前绿箭"},

        {"DI":"DI2","RO":"RO2","name":"前红叉"},

        {"DI":"DI12","RO":"RO3","name":"后绿箭"},

        {"DI":"DI4","RO":"RO6","name":"后红叉"}

]  

核心代码

const convertedArray = assign.map(item => {
    return {
	    name: item[0],
		DI: item[1],
		RO: item[2]
	};
});

完整代码

<template>
	<view>
	view>
template>
<script>
	export default {
		data() {
			return {
 
			}
		},
		methods: {
 
		},
		onLoad() {
			var assign = [
				["前绿箭", "DI10", "RO1"],
				["前红叉", "DI2", "RO2"],
				["后绿箭", "DI12", "RO3"],
				["后红叉", "DI4", "RO6"]
			]
			console.log("整理前",assign)
			const convertedArray = assign.map(item => {
				return {
					name: item[0],
					DI: item[1],
					RO: item[2]
				};
			});
			console.log("整理后",convertedArray)
		}
	};
script>
<style>
 
style>

二、对象数组转换为二维数组

效果

核心代码

const convertedArray = objArray.map(item => [item.name, item.DI, item.RO]);

完整代码 

<template>
	<view>
	view>
template>
<script>
	export default {
		data() {
			return {
 
			}
		},
		methods: {
 
		},
		onLoad() {
			const objArray = [
			  { name: '前绿箭', DI: 'DI10', RO: 'RO1' },
			  { name: '前红叉', DI: 'DI2', RO: 'RO2' },
			  { name: '后绿箭', DI: 'DI12', RO: 'RO3' },
			  { name: '后红叉', DI: 'DI4', RO: 'RO6' }
			];		
			console.log("对象数组",objArray)
			const convertedArray = objArray.map(item => [item.name, item.DI, item.RO]);
			console.log("二维数组",convertedArray);
		}
	};
