我使用的反應護欄寶石來渲染我@records對象。

在 應用程序/資產/ Java腳本/組件/ records.js.coffee

@records = React.createClass 
     render: -> 
      React.DOM.div 
       className: 'records' 
        React.DOM.h2 
         className: 'title' 
         'Records' 

任何人

知道爲什麼我收到此錯誤消息？

Answer 1

我發現問題...... CoffeeScript對間距非常細緻。我需要使用一個製表符間距來啓動該功能，如下所示：

@Records = React.createClass 
    render: -> 
     React.DOM.div 
     className: 'records' 
     React.DOM.h2 
      className: 'title' 
      'Records'
