这样写不对吗？

<uni-nav-bar  
            :class="{ crop: nav.type === 'crop' }"  
            :background-color="nav.bg ? '#fff' : '#0065C5'"  
            :color="nav.bg ? '#000' : '#fff'"  
            :shadow="!nav.bg && !nav.bottom"  
            :border="!nav.bg && !nav.bottom"  
            fixed="true"  
            :left-icon="type[nav.type].left"  
            :right-icon="type[nav.type].right"  
            :right-text="type[nav.type].rightText"  
            :title="nav.title"  
            @click-left="clickLeft"  
            @click-right="clickRight" >  
            <template v-slot="{right}">  
                hehe  
                <view class="crop-icon" v-if="nav.type === 'crop'" @click="$emit('crop')">  
                    haha  
                    <img src="../static/img/main-crop.png"/>
