微信小程序中的店铺评分组件及vue中用svg实现的评分显示组件

<!-- (size * stars.length + (size/2) * 4 + 20 )这里的话，是在可以点击的时候，加上了好评的字体的长度 --><view class='starsBox' style='width:{{isClick?(size * stars.length + (size/2) * 4 + 20 ):(size * stars.length)}}rpx;height:{{size}}rpx;'> <view class='stars' style='width:{{size * stars.length}}rpx;height:{{size}}rpx;'> <block wx:for="{{stars}}" wx:key="{{index}}">  <image src="/images/{{item == 0 ?
