所以我用https://facebook.github.io/react/blog/2016/07/22/create-apps-with-no-configuration.html创建了一个没有配置的应用程序

我安装了mobx和mobx-react,但仍然在@ symb之前显示意外令牌的错误.

我是否需要添加其他内容,或者我当前的配置是错误的？:(

的package.json

"devDependencies": {
"react-scripts": "0.8.4",
"babel-core": "^6.7.6",
"babel-loader": "^6.2.4",
"babel-preset-es2015": "^6.6.0",
"babel-preset-react": "^6.5.0",
"babel-preset-stage-0": "^6.5.0"
},
"dependencies": {
"autobind-decorator": "^1.3.4",
"classnames": "^2.2.5",
"lodash": "^4.15.0",
"mobx": "^2.5.1",
"mobx-react": "^3.5.5",
"react": "^15.3.1",
"react-dom": "^15.3.1",
"validator": "^5.6.0"
 },

.babelrc

{
  "presets": ["es2015", "stage-0", "react"],
  "plugins": [
      "transform-decorators-legacy",
      "transform-class-properties"
  ]
}

和代码

import React, { Component } from 'react';
import { action, observable } from 'mobx'
import {observer} from 'mobx-react';


class App {
    @observer cake = [];
} …

<div class="description_gifts">
<span>Karla Bed</span><img src="images/exit.png" alt="*" /><br />
<span>Quantiy</span><br />
<span>Price</span><br />
<span><strong>Subtotal</strong></span>
</div>

我选择了第一个孩子,但我无法选择下一个跨度的元素

.description_gifts  > span:first-child{}

.description_gifts  > span:first-child + span{} // dont work

如何调用js函数，使其可在点击图片上使用？

$("#closeButton").click(function () {
   $("#sheet").css("display", "none");
});

图片代码？

<img src="images/divclose.png" alt="*"  onclick="function()"/>

Div是 display: none;

当我点击链接或图像时,我改为display: block;工作正常.

当我点击相同的图标或链接时,我希望它能够显示.

因此,如果链接处于活动状态,则会显示Div,然后单击返回链接更改显示选项.
