swiper 组件无法自适应高
内容是图片 图片的mode 设置了 widthFix 属性
<swiper indicator-dots="{{indicatorDots}}" autoplay="{{autoplay}}" interval="{{interval}}" duration="{{duration}}"> <block wx:for="{{imgUrls}}" wx:key="{{index}}"> <swiper-item> <image src="{{item}}" class="slide-image" style="width:100%" mode="widthFix"/> </swiper-item> </block></swiper><button bindtap="changeIndicatorDots"> indicator-dots </button><button bindtap="changeAutoplay"> autoplay </button><slider bindchange="intervalChange" show-value min="500" max="2000"/> interval<slider bindchange="durationChange" show-value min="1000" max="10000"/> duration |
< swiper wx:for='{{array}}' style = 'height:{{ heights[index] || 50 }}px' >
< swiper-item >
< view class = 'getThisHeight' >
...这里放自适应内容
</ view >
</ swiper-item >
</ swiper >
justifyHeight: function () {
let that = this
let hs = []
wx.createSelectorQuery().selectAll( '. getThisHeight ' ).boundingClientRect( function (rects) {
rects.forEach((v, i) => {
hs[i] = v.height
})
that.setData({
heights: hs,
})
}).exec()
},
啊，找了半天swiper-item高度自适应的方法，你这个才是正解啊，太感谢了~~~
.slide-image,swiper-item,swiper{
width:100%;
height:400rpx;
}
使用rpx
