将多维数组转换为特定的字符串格式

我收到一个数组，必须将其转换为特定的字符串格式。

这是数组：

formdata: [
    1: {name: "gender", value: "F", focus: 0, type: "radio"}
    2: {name: "firstname", value: "empty", focus: 0, type: "input"}
    3: {name: "lastname", value: "empty", focus: 0, type: "input"}
    4: {name: "birthday", value: "empty", focus: 0, type: "input"}
    5: {name: "street", value: "empty", focus: 0, type: "input"}
    6: {name: "streetNo", value: "empty", focus: 0, type: "input"}
]

这是应转换为的特定字符串格式：

let formdata = gender.radio|F|0;firstName.text|empty|1;lastName.text|empty|0;street.text|empty|0;houseNumber.text|empty|0;zip.text|empty|0;city.text|empty|0;country.select-one|de|0;birthdate-day.text|empty|0;birthdate-month.text|empty|0;birthdate-year.text|empty|0;email.email|empty|0;code.text|filled_out|0

我认为最好使用JSON.stringify。我已经尝试了以下几种方法：

let formdata = JSON.stringify(
formdata: [
    1: {name: "gender", value: "F", focus: 0, type: "radio"}
    2: {name: "firstname", value: "empty", focus: 0, type: "text"}
    3: {name: "lastname", value: "empty", focus: 0, type: "text"}
    4: {name: "birthday", value: "empty", focus: 0, type: "text"}
    5: {name: "street", value: "empty", focus: 0, type: "text"}
    6: {name: "streetNo", value: "empty", focus: 0, type: "text"}
])
.replace(/(\]\]\,)\[/g, "]\n")..replace(/(\[\[|\]\]|\")/g,"");

他们都没有工作。

任何想法如何解决这个问题？

谢谢！

我认为只是map()在数组上使用。并返回模板字符串。然后join()按';'

const formdata = [
    {name: "gender", value: "F", focus: 0, type: "radio"},
    {name: "firstname", value: "empty", focus: 0, type: "input"},
    {name: "lastname", value: "empty", focus: 0, type: "input"},
    {name: "birthday", value: "empty", focus: 0, type: "input"},
    {name: "street", value: "empty", focus: 0, type: "input"},
    {name: "streetNo", value: "empty", focus: 0, type: "input"},
]


let res = formdata.map(({name,value,focus,type}) => `${name}.${type}|${value}|${focus}`).join(';')

console.log(res)
