的JavaScript ES6调用静态函数从另一个类

Question

这里是静态函数

import alt from '../alt'; 
import Parse from 'parse'; 
import { ElementTypes } from '../constants/ElementTypes'; 

class BoardActions { 

    static getDefaultElement(x, y) { 
     var Element = Parse.Object.extend("Element"); 
     var element = new Element(); 
     element.set("x", x); 
     element.set("y", y); 
     return element; 
    } 
} 

export default alt.createActions(BoardActions); 

类这是谁调用静态函数const startElement = BoardActions.getDefaultElement(0, 3);

import alt from '../alt'; 
import Parse from 'parse'; 
import { ElementTypes } from '../constants/ElementTypes'; 
import BoardActions from './BoardActions'; 

class ProjectActions { 

    createNewProject(name) { 
     return (dispatch) => { 
      dispatch(); 
      const Project = Parse.Object.extend("Project"); 
      const project = new Project(); 
      let projectObject = null; 
      project.set('name', name); 
      project.save().then((object) => { 
       projectObject = object; 
       const startElement = BoardActions.getDefaultElement(0, 3); 
       startElement.set('type', ElementTypes.StartType); 
       startElement.set('root', true); 
       startElement.set('projectId', object.id); 
       return startElement.save(); 
      }).then((object) => { 
       this.newProjectCreated(projectObject); 
      }, (error) => { 
       this.parseError(error); 
      }); 
     } 
    } 

} 

export default alt.createActions(ProjectActions); 

我得到这个错误类：

ProjectActions.js:69 Uncaught TypeError: _BoardActions2.default.getDefaultElement is not a function 

怎么了？

编辑： 我使用babel作为编译器。

"babel-core": "^6.5.1", 
"babel-loader": "^6.2.2", 
"babel-preset-es2015": "^6.5.0", 
"babel-preset-react": "^6.5.0", 
"babel-preset-react-hmre": "^1.1.0", 
"babel-preset-survivejs-kanban": "^0.3.3",

编辑（因为你修改你的问题）：

在第二个文件要导入

import BoardActions from './BoardActions';

这是进口从” ./BoardActions'默认。

看看第一个文件是导出函数的结果而不是类本身。

export default alt.createActions(BoardActions);
