Browserify/Reactify - Uncaught ReferenceError: function is not defined

Question

我正在尝试抽象我的代码，并且我在以下结构中有以下两个文件

main.js
  components
  - parent.js

main.js

require('./components/Parent');

ReactDOM.render(
    <Parent />,
    document.getElementById('content')
);

components/Parent.js

var Parent = React.createClass({
  displayName: 'Parent',
  render: function(){
    return (
      <div>
        <div> This is the parent page. </div>
      </div>
    )
  }
});

index.html

<div id="app">  
</div>

我运行下面-

browserify -t reactify main.js -o main_js.js

这是它创建的javascript

(function e(t,n,r){function s(o,u){if(!n[o]){if(!t[o]){var a=typeof require=="function"&&require;if(!u&&a)return a(o,!0);if(i)return i(o,!0);var f=new Error("Cannot find module '"+o+"'");throw f.code="MODULE_NOT_FOUND",f}var l=n[o]={exports:{}};t[o][0].call(l.exports,function(e){var n=t[o][1][e];return s(n?n:e)},l,l.exports,e,t,n,r)}return n[o].exports}var i=typeof require=="function"&&require;for(var o=0;o<r.length;o++)s(r[o]);return s})({1:[function(require,module,exports){
require('./components/Parent');

ReactDOM.render(
    React.createElement(Parent, null),
    document.getElementById('content')
);

},{"./components/Parent":2}],2:[function(require,module,exports){
var Parent = React.createClass({
  displayName: 'Parent',
  render: function(){
    return (
      React.createElement("div", null, 
        React.createElement("div", null, " This is the parent page. ")
      )
    )
  }
});

},{}]},{},[1]);

运行 页面在第 5 行抱怨 React.createElement(Parent, null),

Uncaught ReferenceError: Parent is not defined

但是如您所见，文件已加载，为什么在文件中找不到它？

Answer 1

将require('./components/Parent');更改为var Parent = require('./components/Parent');

您需要指定分配给它的变量的名称。另外，如果将它们放在不同的模块中，则需要导出模块。

// in ./components/Parent
module.exports = Parent;
