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]
	};
});

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]);
