增加业务逻辑，调用子组件表单验证~~~
methods: {beforeHandleTabsClick: function (index) {if (this.activeTabsIndex === "1" && (index === "2" || index === "3")) {let reValidState = this.$refs.baseForm.sumbitForm();if (reValidState) {this.activeTabsIndex = index;return true;}return false;} else if (this.activeTabsIndex === "2" &&(index === "1" || index === "3")) {return true;}},
}
)
)
