javascript - Vue 2 : Unable to find method on click event from component

Question

在我的 vue 应用程序中，我正在调用位于组件中的单击事件的函数。这是组件代码:

Vue.component( 'new-board', {
  template: `
    <div>
      <br/>
      <div class="panel panel-primary">
        <div class="panel-heading">
          Create New Board
        </div>
        <div class="panel-body">
          <input class="form-control" placeholder="Board Name"/>
          <button 
            style="margin-top: 5px;" 
            @click.stop="addBoard"
            class="btn btn-success btn-xs btn-block"
          >
            Add Board
          </button>
        </div>
      </div>
    </div>
  `
} )

这是 vue 应用实例:

var boardItem = new Vue( {
  el: "#board-item",
  data: {
    boards: [
      { name: 'learning vue 2' }
    ],
    newBoard: [],
    viewNewBoard: true
  },
  methods: {
    displayNewBoard: function() {
      event.preventDefault()
      if( this.viewNewBoard == false ) {
        this.viewNewBoard = true
      } else {
        this.viewNewBoard = false
      }
    },
    addBoard: function() {
      console.log( 'add board' )
    }
  }
} )

现在，当我单击上述组件中的添加板按钮时，它显示以下错误:

Uncaught ReferenceError: addBoard is not defined at click (eval at Xr (vue.min.js:7), :2:455) at HTMLButtonElement.invoker (vue.min.js:6)

组件中的按钮好像找不到addBoard方法，它是写在同一个文件中的! 我在这里缺少什么？

尝试:

Vue.component( 'new-board', {
  template: `
    <div>
      <br/>
      <div class="panel panel-primary">
        <div class="panel-heading">
          Create New Board
        </div>
        <div class="panel-body">
          <input class="form-control" placeholder="Board Name"/>
          <button 
            style="margin-top: 5px;" 
            @click.stop="addBoard"
            class="btn btn-success btn-xs btn-block"
          >
            Add Board
          </button>
        </div>
      </div>
    </div>
  `,
  methods: {
    addBoard: function(){ console.log('add board');}
  }
} )
