u-badge小红点传value

例如noticeCount

                    <view style="position: relative;">
                        <u-icon name="chat" color="#2979ff" size="60rpx"></u-icon>
                        <u-badge style="position: absolute; top: -5rpx; right: -10rpx;" type="error"
                            numberType="overflow" max="99" :value="noticeCount"></u-badge>
                    </view>

or v-model:

                    <view style="position: relative;">
                        <u-icon name="chat" color="#2979ff" size="60rpx"></u-icon>
                        <u-badge style="position: absolute; top: -5rpx; right: -10rpx;" type="error"
                            numberType="overflow" max="99" v-model="noticeCount"></u-badge>
                    </view>
