javascript - CoffeeScript 被转换为错误的 javascript

Question

我有以下 CoffeeScript

Excelsior.TopicView = Ember.View.extend
templateName: 'topic',
    didInsertElement :() ->
      this._super()
      Ember.run.scheduleOnce 'afterRender', this, ->
        converter = new Markdown.Converter()
    editor = new Markdown.Editor(converter)
    editor.run()

它生成的 javascript 是

(function() {
  Excelsior.TopicView = Ember.View.extend({
  templateName: 'topic',
  didInsertElement: function() {
    var editor;
    this._super();
    Ember.run.scheduleOnce('afterRender', this, function() {
      var converter;
      return converter = new Markdown.Converter();
    });
    editor = new Markdown.Editor(converter);
    editor.run();
   }
 });

}).call(this);

这是不正确的，我真正想要生成的是

(function() {
  Excelsior.TopicView = Ember.View.extend({
  templateName: 'topic',
  didInsertElement: function() {
    this._super();
    Ember.run.scheduleOnce('afterRender', this, function() {
      var converter= new Markdown.Converter();
      var editor = new Markdown.Editor(converter);
      editor.run();
    });
   }
 });
}).call(this);

如何修复我的 CoffeeScript ？

Answer 1

您需要小心缩进(确保没有混合使用空格和制表符):

Excelsior.TopicView = Ember.View.extend
  templateName: 'topic',
  didInsertElement :() ->
    this._super()
    Ember.run.scheduleOnce 'afterRender', this, ->
      converter = new Markdown.Converter()
      editor = new Markdown.Editor(converter)
      editor.run()
