2/10/2017来源:心得技巧人气:2673

功能: 1.分页栏与滑动视图绑定 2.点击分页栏自动滑动到对应视图 3.滑动的到视图对应分页栏自动显示选中样式 效果图 这里写图片描述

上代码 wxml

<view class="tapNav"> <view class="{{tabArr.tabCurrentIndex==0?'active':''}}" data-index="0" bindtap="veHandle">分页标签1</view> <view class="{{tabArr.tabCurrentIndex==1?'active':''}}" data-index="1" bindtap="veHandle">分页标签2</view> <view class="{{tabArr.tabCurrentIndex==2?'active':''}}" data-index="2" bindtap="veHandle">分页标签3</view> </view> <swiper id="swiper" indicator-dots="{{indicatorDots}}" autoplay="{{autoplay}}" interval="{{interval}}" duration="{{duration}}" current="{{current}}" bindchange="swiperChange"> <block wx:for="{{imgUrls}}"> <swiper-item id="swiper-item"> <image id="imgae" src="{{item}}" class="slide-image" width="355" height="150"/> </swiper-item> </block> </swiper>

wxss

/* 1.横向排列分页标签 2.每个分页标签各占1/3 */ .tapNav { display: flex; flex-direction: row; } .tapNav view{ flex:1; width:200rpx; height:100rpx; text-align: center; line-height: 100rpx; font-family: "微软雅黑"; } /*选中样式*/ .tapNav .active { color:blue; border-bottom:4rpx solid mediumseagreen; } #swiper { margin-top:40rpx; } #swiper image{ width:100%; }
