vue provide inject使用

父组件rootA001

....
 
  provide() {
    //return {
      // this.refreshCurrentTab对应methods中的方法，无括号
      //refreshCurrentTab: this.refreshCurrentTab
    //}
 
    return {
      refreshCurrentTab: () => {
        return this.refreshCurrentTab()
      }
    }
  },
 
  methods: {
    refreshCurrentTab() {
         .....
    }
   .....
 }
......

任意子孙组件：

...
  inject: ['refreshCurrentTab'],
  methods:{
 
     getXXX(){
        ... 
    },
    
    submitForm() {
     ....
    // 调用祖级组件rootA001的方法
     this.refreshCurrentTab()
     ......
    },
   ......
   
}
