        <view class="lu-popup-content" :class="popupContentClass"  :style="[{height:height,width:width,backgroundColor:backgroundColor,borderRadius:bor}]">
            <slot></slot>
        </view>
        <view v-if="maskShow" class="lu-popup-mask" :class="popupMaskClass" @tap.stop="close(maskClick)"></view>
