我使用Webpack + html-webpack-plugin来构建我的所有静态文件。问题是,当我使用谷歌地图API时,它无法正常工作。
我有这段代码:
var map;
function initMap() {
map = new google.maps.Map(document.getElementById('map'), {
center: {lat: -34.397, lng: 150.644},
zoom: 6
});
// the other code, irrelevant
}
一个HTML文件:
<!doctype html>
<html>
<head>
</head>
<body>
<div id="map"></div>
<script async="async" defer="defer"
src="https://maps.googleapis.com/maps/api/js?key=<token here>&callback=initMap">
</script>
<script src="script.js"></script>
</body>
</html>
如果我只运行此文件,一切正常。但是如果我运行它,webpack就会抱怨initMap不是一个函数&#39;。我查看了输出内部,似乎initMap被声明为不是全局函数,而是作为模块中的函数或类似的东西,所以可能是问题。
我应该如何在webpack中使用Google Maps API?我知道我可以用我的脚本捆绑一些libs,比如反应,我应该这样做吗?这里的方法应该是什么?
UPD:这是我的webpack.config.js:
/* eslint-disable */
const path = require('path')
const fs = require('fs')
const webpack = require('webpack')
const HtmlWebpackPlugin = require('html-webpack-plugin')
const nodeModules = {}
fs.readdirSync('node_modules')
.filter(function(x) {
return ['.bin'].indexOf(x) === -1
})
.forEach(function(mod) {
nodeModules[mod] = 'commonjs ' + mod
})
const htmlMinifierObj = {
collapseWhitespace: true,
removeComments: true
}
module.exports = [
// the first object compiles backend, I didn't post it since it's unrelated
{
name: 'clientside, output to ./public',
entry: {
script: [path.join(__dirname, 'clientside', 'script.js')]
},
output: {
path: path.join(__dirname, 'public'),
filename: '[name].js'
},
module: {
loaders: [
{
test: /\.js$/,
loader: 'babel',
query: { presets:['es2015', 'stage-0'] }
}
],
},
plugins: [
//new webpack.optimize.UglifyJsPlugin({minimize: true}),
new HtmlWebpackPlugin({
template: 'clientside/index.html',
inject: 'body',
chunks: ['script'],
minify: htmlMinifierObj
})
],
}]
输出HTML是(我已从我的源文件中删除导入script.js
,因为它是由webpack添加的,并且为了便于阅读而关闭了最小化):
<!doctype html>
<html>
<head>
</head>
<body>
<a href="/login/facebook">Login</a>
<div id="map"></div>
<script async defer
src="https://maps.googleapis.com/maps/api/js?key=AIzaSyCGSgj5Ts10UdapzUnWlr34NS5cuoBj7Wg&callback=initMap">
</script>
<script type="text/javascript" src="script.js"></script></body>
</html>
答案 0 :(得分:27)
在script.js
中在函数声明之后,将函数添加到全局范围,如下所示:
function initMap() {
// Some stuff
}
window.initMap = initMap;
