React.createClass

Question

我有一个范围问题，我很难解决。

我将getTrackNotes导入到es6模块中，我想按照下面的内容在React类中引用它，但这被设置为Track（React Class）。

我如何参考？

import { getTrackNotes } from '../utils/immutableInstruments';

const Track = React.createClass({

    componentDidMount() {

        const { trackId } = this.props.params;

        function updateTimeSequencer (socket, state, getTrackNotes, TimeSequencer, instruments, trackId)
        {

            //I want to call getTrackNotes here, but the scope is set to the Track React class
            **getTrackNotes();**

        }
        var instruments = this.props.instruments;

        socket.on('state', updateTimeSequencer.bind(this, socket));
     }

Answer 1

您的getTrackNotes函数将从顶级作用域继承，但您使用相同的名称函数参数覆盖它。只需从函数参数列表中删除getTrackNotes或将参数重命名为其他内容：

function updateTimeSequencer (socket, state, thisIsSomethingElse, TimeSequencer, instruments, trackId)
