报错内容
[Vue warn]: Extraneous non-emits event listeners (refreshRelationList) were passed to component but could not be automatically inherited because component renders fragment or text root nodes. If the listener is intended to be a component custom event listener only, declare it using the "emits" option.
翻译:
无关的非发出事件侦听器(refreshRelationList)被传递给组件,但不能自动继承,因为组件呈现片段或文本根节点。如果侦听器只打算作为组件自定义事件侦听器,则使用"emit "选项声明它。
报错原因/解决方法
1.没有通过defineEmits(["refreshRelationList"])定义。
2.该子组件中存在多个根节点。(改为一个)
