Cannot use v-for on stateful component root element because it renders multiple elements.

<template name:trailerStars>
    <image v-for="yellow in yellowScore"
    src="../static/icos/star-yellow.png" class="star-ico">
    </image>
    <image v-for="gray in grayScore"
    src="../static/icos/star-gray.png" class="star-ico">
    </image>  
</template>

 

错误原因:

不能在根元素(root element)使用 v-for,因为v-for是个循环体呈现多个元素,v-for在根元素上导致无法渲染。

解决方案:

将元素包裹到另外的标签中:

 

<template name:trailerStars>
    <view>
        <image v-for="yellow in yellowScore"
        src="../static/icos/star-yellow.png" class="star-ico">
        </image>
        <image v-for="gray in grayScore"
        src="../static/icos/star-gray.png" class="star-ico">
        </image>
    </view>
    
</template>
