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>
