Javascript导入函数语法 [英] Javascript import function syntax

问题描述

我正在尝试从另一个模块导入一个函数，但在运行时遇到错误：

I am trying to import a function from another module but on running am getting an error:

TypeError: _this.getData is not a function.

data.js

function getData() {
  return [
    { id: 1,
      name: 'Pluto',
      type: 'Dwarf Planet'
    },
    { id: 2,
      name: 'Neptune',
      type: 'Planet'
    }
  ]
}
export { getData }

worker.js

worker.js

import getData from data.js

this.data = this.getData()

然后在运行中我得到如上所述的浏览器错误。关于我做错的任何想法？

Then on run I get the browser error as mentioned above. Any ideas as to what I am doing incorrectly?

推荐答案

使用getData（）时应省略this关键字它不属于当前对象。

You should omit the "this" keyword when using "getData()" it doesn't belong on the current object.

function getData() { .... }

export default getData;

import getData from "data.js"

this.data = getData();
