    props: {
            //primary,warning,green,danger,white，black，gray
            type: {
                type: String,
                default: 'primary'
            },
            // '', small
            size: {
                type: String,
                default: ''
            },
            //是否是圆点
            dot: {
                type: Boolean,
                default: false
            },
            //是否可见
            visible: {
                type: Boolean,
                default: true
            }
