Babel转ES5后IE8下的兼容性问题解决方案

1、webpack配置文件，增加插件transform-es3-property-literals和transform-es3-member-expression-literals

const webpackdevConfig = {
  entry: entry,
  output: {
    path: path.join(__dirname, 'dist/js'),
    filename: '[name].js',
    publicPath: '/static/'
  },
  plugins: [
    new webpack.NoErrorsPlugin(),
  ],
  module: {
    loaders: [
      {
        test: /\.js$/, loader: ['babel'], include: [path.join(new_dir, 'src')],
        query:{
          "presets": ["es2015", "stage-0"],
          "plugins" : [
            "transform-es3-property-literals",
            "transform-es3-member-expression-literals",
          ]
        }
      },
      {test: /\.scss$/, loaders: ['style', 'css', 'sass'], include: path.join(new_dir, 'src/style')},
      {test: /\.(jpg|png)$/, loader: 'url-loader?limit=8192', include: path.join(new_dir, 'src/img')}
    ]
  }
}

2、模块导出不能使用 export default ，改为export { xxx }
3、模块引入使用 import { } from 'xxx'
4、引入es5-shim.min.js和es5-sham.min.js
