React的函數綁定一致是個問題,主要有下面幾種方式:html
export default class Com extends React.Component { render() { <input type="button" value="點我" onClick={this.method.bind(this)} /> } }
export default class CartItem extends React.Component { constructor(props) { super(props); this.method = this.method.bind(this); } render() { <input type="button" value="點我" onClick={this.method} /> } }
export default class CartItem extends React.Component { const method2 = () =>{...} constructor(props) { super(props); this.method = (ev) => {...} } render() { <input type="button" value="點我" onClick={this.method} /> } }
這個是babel支持的,還不是標準react
export default class CartItem extends React.Component { method = () => {...}; render() { <input type="button" value="點我" onClick={this.method} /> } }
export default class CartItem extends React.Component { method(){...}; render() { <input type="button" value="點我" onClick={::this.method} /> } }
最後一種很帥氣, 然並軟,我使用就直接報錯。 臣不服,不服。
因而尋找方案, 由於是create-react-app建立的項目。
個人思考方案以下webpack
const rewireMobX = require('react-app-rewire-mobx'); const rewireEslint = require('react-app-rewire-eslint'); const {injectBabelPlugin} = require('react-app-rewired'); /* config-overrides.js */ module.exports = { webpack: function override(config, env) { config = rewireEslint(config, env); config = rewireMobX(config, env); config = injectBabelPlugin('transform-function-bind',config) config.output.publicPath = '' return config; } }
修改完畢,啓動,哦,能夠。 真是不錯。
扔掉鍵盤,甩開鼠標,深深的一口水,想寫行代碼咋這麼難。git
