我使用webpack来构建React组件。 这是JSX文件:
'lifetime' => 120, // in minutes, default 2 hours
'expire_on_close' => false,
然后,我想在html中调用函数// index.js
var React = require('react');
var ReactDOM = require('react-dom');
var renderHelloComponnet = function(id) {
ReactDOM.render(
<h1>Hello, World!</h1>,
document.getElementById(id)
);
}
我有webpack的配置文件:
renderHelloComponnet
但是我无法在html中呈现我的组件:
module.exports = {
entry: {
index: './src/index.js'
},
output: {
path: __dirname + '/build',
filename: '[name].bundle.js',
libraryTarget: "var",
library: ["ABC"],
},
resolve: {
extensions: ['', '.js', '.jsx']
},
module: {
loaders: [
{
test: /\.jsx?$/,
loader: 'babel-loader',
exclude: /node_modules/,
query: { presets:['react'] }
}
]
}
}
我收到错误:<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8" />
<title>Hello React!</title>
<script type="text/javascript" src="./build/index.bundle.js"></script>
</head>
<body>
<div id="example"></div>
<script type="text/javascript">
ABC.renderHelloComponnet('example');
</script>
</body>
</html>
答案 0 :(得分:3)
您在module.exports
中导出的内容是library
var中的内容。因此,如果您index.js
导出renderHelloComponent
:
module.exports = renderHelloComponent;
然后在你的ABC
var中你将得到函数:
<script type="text/javascript">
ABC('example');
</script>
如果您希望library
var实际拥有renderHelloComponent
方法,则可以使用此函数导出对象:
module.exports = {
renderHelloComponent: renderHelloComponent
}
然后你就可以做到这一点:
<script>
ABC.renderHelloComponent('example');
</script>
