javascript - 将数组转换为JavaScript中的对象

Question

我正在尝试在不支持ES6的Google表格应用脚本中对大量数据进行排序! (我认为)

数组看起来像这样
var data = [[“” Frank“，” franck@gmail.com“，21]，[” Mark“，” Mark@gmail.com“，23]]

我很喜欢将数组变成对象的想法，在这里我可以通过ex名称访问每个对象:

Frank.name
Frank.email
Frank.age

我尝试了以下

function Driver(name, email, age) {
    this.name= name;
    this.email= email;
    this.age = age;
  }

然后

for(var i=0; i<data.length; i++){
  data[i][0]= new Driver (data[i][0],data[i][1],data[i][2])
}

但这不起作用
你能帮我吗？

Answer 1

如果我了解您的要求

我很喜欢将数组变成对象的想法，可以在其中按名称访问每个对象

正确，那么解决方案就是这样简单:

ES6版本

function Driver(name, email, age) {
    this.name= name;
    this.email= email;
    this.age = age;
}

const data = [["Frank","franksmail",2], ["name2", "mail2", 3], ["name3", "mail3", 4]]


const mappedData = data
//map the array of arrays to an array of Drivers
.map(props => new Driver(...props))
//reduce the array of drivers to a single object
.reduce((accumulator, currentDriver) => {
    accumulator[currentDriver.name] = currentDriver
    return accumulator
}, {})


console.log(mappedData)
console.log(mappedData.Frank.email)

ES5版本:

function Driver(name, email, age) {
    this.name= name;
    this.email= email;
    this.age = age;
}
var data = [["Frank","franksmail",2], ["name2", "mail2", 3], ["name3", "mail3", 4]]


var mappedData = data
//map the array of arrays to an array of Drivers
.map(function (props) {
  return new Driver(props[0], props[1], props[2])
})
//reduce the array of drivers to a single object
.reduce(function (accumulator, currentDriver) {
    accumulator[currentDriver.name] = currentDriver
    return accumulator
}, {})


console.log(mappedData)
console.log(mappedData.Frank.email)

警告:
如果必须在 name数组中使用具有相同 data的Divers，则将其中之一放开。
