Question

我需要调用结果（来自函数的数组）在函数外部调用

我的代码看起来像这样

import axios from 'axios'
var cheats
(() => {
  axios.get('api/cheats/getcheaternames')
  .then((response) => {
    cheats = response.data
    console.log(cheats, 'yeah')//results[Good, Bad]
    return cheats
  })
  .catch((error) => {
     console.log(error, 'err')
  })
})()

const it = [
    {
        name: ...
    }
]

这是我对结果进行硬编码的方式，

const it = [
   {
      name: 'Good'
   },
   {
      name: 'Bad'
   },
   {
      name: 'Handsome'
   }
]

是否有动态填充it变量的想法？

更新

我没有足够的声誉回答我自己的问题，这就是我重构代码以使其工作的方式

import axios from 'axios'

var cheats
var it = []
let myFirstPromise = new Promise((resolve, reject) => {
    setTimeout(() => {
       resolve(axios.get('api/cheats/getcheaternames')
        .then((response) => {
            cheats = response.data
            return cheats
        })
        .catch((error) => {
            console.log(error, 'err')
        }))
    }, 250)
})

myFirstPromise.then((successMessage) => {
// for (var i = 0; i < successMessage.length; i++) {
//     it.push({name: i})
// }
   for (const value of successMessage) {
      it.push({name: value})
   }
})

export default {
  items: [
    {
        name: 'Dashboard',
        url: '/dashboard',
        icon: 'icon-speedometer',
        badge: {
            variant: 'primary',
            text: 'Cheaters'
        }
    },
    {
        title: true,
        name: 'Elements',
        class: '',
        wrapper: {
            element: '',
            attributes: {}
        }
    },
    {
        name: 'Cheats',
        url: '/components',
        icon: 'icon-puzzle',
        children: it
    },
    {
        name: 'Angular Version',
        url: 'https://angular.herokuapp.com/',
        icon: 'icon-cloud-download',
        class: 'mt-auto',
        variant: 'success'
    }
]

}

任何想要使这些代码更好的想法都值得赞赏。我错过了什么，或者我是否正确使用此代码？

并不完全清楚您提出的问题，但如果您要问如何更改items变量，请将其更改为let而不是const，将您的代码更改为：

.then((response) => {
    cheats = response.data;
    console.log(cheats, 'yeah')//results[Good, Bad]
    items = response.data.map(item => ({ name: item }));
    return cheats
 })

从Function中的结果填充数组对象
