buefy编程模式从子级获取父级中的数据

Question

使用buefy编程模式，如何在关闭事件时将数据从子组件返回到父组件。我有以下方法我可以收听关闭事件，但我不知道如何获得数据

settings(question, option, index) {
this.$modal.open({
component: ModalConent,
parent: this,
props: {
"question": question,
"option": option,
"index": index
},
onCancel: function () {
console.log()
},
events: {
}
})
},

Answer 1

您可以使用events道具来获取customEvent:

this.$modal.open({
component: ModalConent,
parent: this,
props: {
"question": question,
"option": option,
"index": index
},
onCancel: function () {
console.log()
},
events: {
'customEvent': value => {
console.log(value)
}
}
})

并在您的子组件中发射customEvent

this.$emit('customEvent', value)
