当我使用Babel&Webpack编译ES6时,在IE11中出现此错误:
“对象不支持属性或方法'append'”
我环顾了互联网,并在这里找到了解决方案:Polyfill (developer.mozilla.org)我将这段代码粘贴到了源js文件中,并且在与Babel进行编译时,IE11不再显示该错误。 但是 ...
是否可以使用Babel和Webpack进行转换,而不必像我一样手动粘贴代码?
这是我的 .babelrc
文件:
{
"presets": [
["@babel/preset-env", {
"useBuiltIns": "usage",
"corejs": 3,
"debug": true
}]
]
}
这是我的 webpack.config.js
文件:
const path = require('path');
const TerserPlugin = require('terser-webpack-plugin');
module.exports = {
entry: [
'./node_modules/core-js/stable',
'./node_modules/regenerator-runtime/runtime',
'./src/index.js'
],
mode: 'development',
output: {
filename: 'main.js',
path: path.resolve(__dirname, 'dist')
},
module: {
rules: [{
test: /\.js$/,
exclude: /node_modules/,
use: {
loader: 'babel-loader',
}
}]
},
optimization: {
minimize: true,
minimizer: [new TerserPlugin()],
},
};
而且,这是我的 package.json
文件:
{
"name": "Demo Project",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1",
"dev": "webpack --watch"
},

"> .05% in ES",
"not ie <= 9"
],
"dependencies": {

}
我需要一个额外的插件吗?还是我留下了一些东西?
无论如何,谢谢!

Babel是JavaScript编译器。它填充了JS语言功能。但是append
是DOM功能,因此babel不能对其进行多填充。您可以使用ember-cli-polyfill-io来填充DOM。
