解決辦法有兩種
- 一、通過判斷其數(shù)組長度
- 二、將兩種情況分開寫&＃xff0c;大于要設置的數(shù)量時&＃xff0c;寫一種樣式&＃xff0c;小于時&＃xff0c;再寫一種樣式
解決方案一&＃xff1a;
swiper class&＃61;"swiperMain" autoplay&＃61;"false" current&＃61;"0" interval&＃61;"3000" duration&＃61;"500" circular&＃61;"true" indicator-dots&＃61;"{{false}}" display-multiple-items&＃61;"{{finalObj.imageInfo.length>2?3:finalObj.imageInfo.length}}">swiper-item class&＃61;"item" wx:for&＃61;"{{finalObj.imageInfo}}" wx:for-item&＃61;"items" wx:key&＃61;"index">image src&＃61;"{{items}}">image>swiper-item>

解決方案二
block wx:if&＃61;"{{finalObj.imageInfo.length>2}}">swiper class&＃61;"swiperMain" autoplay&＃61;"true" current&＃61;"0" interval&＃61;"2000" duration&＃61;"1000" circular&＃61;"true" indicator-dots&＃61;"{{false}}" display-multiple-items&＃61;&＃39;3&＃39;>swiper-item class&＃61;"item" wx:for&＃61;"{{finalObj.imageInfo}}" wx:for-item&＃61;"items" wx:key&＃61;"index">image src&＃61;"{{items}}">image>swiper-item>swiper>
block>
block wx:else>view class&＃61;"img_normal_box">image wx:for&＃61;"{{finalObj.imageInfo}}" wx:for-item&＃61;"items" wx:key&＃61;"index" class&＃61;"img_normal" alt&＃61;"" src&＃61;"{{items}}">image>view>
block>
