我的浏览器中出现以下错误:

Uncaught Error: Invariant Violation: The style prop expects a mapping from style properties to values, not a string. For example, style={{marginRight: spacing + 'em'}} when using JSX.

这是运行 webpack-dev-server 并转到 localhost:8080 时的情况。

./modules/main.js:

/** @jsx React.DOM */

var React = require('react');
var HoverAction = require('./HoverAction/HoverAction');

var Application = React.createClass({
render: function() {
return (
<div>
<HoverAction title="favorite" />
</div>
);
}
});


if (typeof window !== 'undefined') {
React.render(<Application />, document.getElementById('app'));
}

./modules/HoverAction/HoverActions.js:

/** @jsx React.DOM */
'use strict';

var StyleSheet = require('react-style');
var React = require('react');

var HoverActionStyles = StyleSheet.create({
normal: {
height: '200px',
width: '200px',
border: '1px solid black'
}
});

var HoverActionTitleStyle = StyleSheet.create({
normal: {
textAlign: 'center',
fontSize: '10px'
}
});

var HoverAction = React.createClass({
render: function() {
return (
<div style={HoverActionStyles.normal}>
<div ></div>
<div style={HoverActionTitleStyle.normal} >{this.props.title}</div>
</div>
);
}
});

module.exports = HoverAction;

index.html:

<!doctype html>
<html>
<head>
<link rel="stylesheet" href="bundle.css">
</head>
<body>
<div id="app"></div>
<script src="bundle.js"></script>
</body>
</html>

webpack.config.js:

'use strict';

var ReactStylePlugin = require('react-style-webpack-plugin');
var ExtractTextPlugin = require('extract-text-webpack-plugin');

var webpack = require('webpack');

module.exports = {
devtool: 'sourcemap',
entry: './modules/main.js',
output: {
filename: 'bundle.js',
},
module: {
loaders: [
{
test: /\.js$/,
loaders: [
ReactStylePlugin.loader(),
'jsx-loader?harmony'
]
},
{
test: /\.less$/,
loader: 'style-loader!css-loader!less-loader'
},
{
test: /\.css$/,
loader: ExtractTextPlugin.extract('css-loader')
// loader: 'style-loader!css-loader'
},
{
test: /\.(png|jpg)$/,
loader: 'url-loader?limit=8192'
} // inline base64 URLs for <=8k images, direct URLs for the rest
]
},
plugins: [
new ReactStylePlugin('bundle.css'),
new webpack.DefinePlugin({
'process.env': {
// To enable production mode:
// NODE_ENV: JSON.stringify('production')
}
})
]
};

package.json:

{
"name": "webpack-howto-example",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"start": "webpack-dev-server",

最佳答案

React Style 要求您使用 styles 属性而不是 style

var HoverAction = React.createClass({
render: function() {
return (
<div styles={HoverActionStyles.normal}>
<div ></div>
<div styles={HoverActionTitleStyle.normal} >{this.props.title}</div>
</div>
);
}
});
