使用Vue保存输入并在其他字段上显示。

Question

我在如何设置方法上遇到了麻烦。我希望在点击保存按钮后，输入的数据能显示在我的表格上。我的方向是否正确。因为现在没有点击保存就显示在表上了。谁能帮我写写代码吗，谢谢。

你应该添加一些 state 属性，用于控制何时显示表格数据

new Vue({
  el: "#app",
  data: () => {
    return {
    	visible: false,
      
      height: null,
      neck: null,
      biceps: null,
      hips: null,
      quad: null,
      chest: null,
      waist: null,
      calve: null,
      boneweight: null,
      bodyweight: null
    }
  },
  
  methods: {
    addItems() {
    	this.visible = true
    }
  }
})
