问题

原因

比如下面 ​​mounted: {},​​​ 应该写成 ​​mounted() {},​​

export default {
  props: {
    value: Boolean,
  },
  data () {
    return {
      
    };
  },
  components: {
    
  },
  created() {
    
  },
  mounted: {
    
  },
  methods: {
    handleClose() {
      this.$emit("input", false);
    },
  },
};
