一维数组实现
const obj = [
name: '张飒',
age: 13,
phone: 123
,
name: '凯苏',
age: 15,
phone: 963
,
name: 'Jk',
age: 16,
phone: 852
,
name: '库洛',
age: 17,
phone: 741
]
// Object.entries 依据对象的键值对形成数组
// join(',') 数组转字符串
// split(",") 将字符串进行分割
const newArray = []
const arr = obj.map(item =>
const resultString = Object.entries(item).join(',').split(",")
/**
resultString 输出结果
["name","张飒","age","13","phone","123"]
["name","凯苏","age","15","phone","963"]
["name","Jk","age","16","phone","852"]
["name","库洛","age","17","phone","741"]
*/
resultString.forEach(key =>
newArray.push(key)
)
)
console.log(newArray)
// ["name","张飒","age","13","phone","123","name","凯苏","age","15","phone","963","name","Jk","age","16","phone","852","name","库洛","age","17","phone","741"]
二维数组实现
const obj = [
name: '张飒',
age: 13,
phone: 123
,
name: '凯苏',
age: 15,
phone: 963
,
name: 'Jk',
age: 16,
phone: 852
,
name: '库洛',
age: 17,
phone: 741
]
const arr = obj.map(item =>
const resultString = Object.entries(item).join(',').split(",")
return resultString.map(item => item)
)
console.log(arr)
// [["name","张飒","age","13","phone","123"],["name","凯苏","age","15","phone","963"],["name","Jk","age","16","phone","852"],["name","库洛","age","17","phone","741"]]
