computed: { addButtonDisabled() { return this.$refs.queryBox.selectSportsType === _const.ALL_SELECTION
},
報錯，Error in render: "TypeError: Cannot read property 'selectSportsType' of undefined"百度了下computed: {
addButtonDisabled() { this.$nextTick(()=>{ return this.$refs.queryBox.selectSportsType === _const.ALL_SELECTION
})
},這樣才可以獲取到可是這樣又沒辦法用computed了，請問有什么解決辦法嗎，謝謝
我要在父組件的computed中使用子組件的值，有什么辦法嗎？
