Question

我正在尝试使用decorate中的mobx-react制作可观察的属性但是，我收到错误：

Uncaught TypeError: Object(...) is not a function
    at Object../src/vrp-ui/Button.js (Button.js:32)
    at __webpack_require__ (bootstrap 8330eff5292135af9e26:19)

    at Object.0 (Button.js:32)
    at __webpack_require__ (bootstrap 8330eff5292135af9e26:19)

这是我的实施：

import React, { Component } from 'react'
import {Button} from 'semantic-ui-react'
import axios from 'axios'

import { decorate, observable } from "mobx"

class componentName extends Component {

    //@observable vrp_solution = {};

    constructor () {
        super()
        this.state = {
          solution: []
        }
        this.handleClick = this.handleClick.bind(this)
      }

      handleClick () {
        axios.post('http://localhost:8000/vrp/')
          .then(response => {
            vrp_solution= "!";
            console.log(response)})
      }


  render() {
    return (
      <Button onClick={this.handleClick}>
        Calculate Best Routes!
      </Button>
    )
  }
}

export default decorate(componentName,{vrp_solution: observable });


#Error is here: 

export default decorate(componentName,{vrp_solution: observable });

如果我删除decorate错误消失了.. 任何想法？

Answer 1

装饰和观察来自mobx而不是mobx-react，尝试，

从“mobx”导入{decorate，observable}

你的按钮也应该是

<Button>
   Calculate Best Routes!
</Button>

使用decorate时，Object（...）不是函数
