Webpack 的 HtmlWebpackPlugin 如何控制某个 chunks 的 inject 位置？

HtmlWebpackPlugin

new HtmlWebpackPlugin({
filename: 'index.html',
template: './src/index.jade',
inject: {
head: ['chunks2'],
body: ['chunks1', 'chunks3', 'vendor']
},
chunks: ['chunks1', 'chunks2', 'chunks3', 'vendor']
})

// ...

// 如果 inject 传入参数为对象则区分打包.
if (typeof this.options.inject === 'object') {
this.options.inject.head.forEach(value => {
var injectScripts = scripts.filter(script => script.attributes.src.indexOf(value) > -1)
head = head.concat(injectScripts)
})

this.options.inject.body.forEach(value => {
var injectScripts = scripts.filter(script => script.attributes.src.indexOf(value) > -1)
body = body.concat(injectScripts)
})
} else {
// 原版逻辑.
if (this.options.inject === 'head') {
head = head.concat(scripts);
} else {
body = body.concat(scripts);
}
}

// ...
