            import elementResizeDetectorMaker from 'element-resize-detector'; //插件
            //监听元素宽度变化
            const _this = this;
            const erd = elementResizeDetectorMaker();
            erd.listenTo(document.getElementById('kd-verify'), element => {
                _this.$nextTick(() => {
                    const width = element.offsetWidth;
                    _this.verifyWidth = width;
                    //监听到事件后执行的业务逻辑
                    console.log('监听到事件后执行的业务逻辑', _this.verifyWidth, typeof _this.verifyWidth);
                });
            });
