wxss样式如下:
.wx-swiper{height: 750rpx; }
.wx-image{width: 100%; height: 100%; }
其中indicator-dots=”True”表示有指示点;interval=”2000”表示自动切换时间间隔。
底部是一个view来展示当前显示的item,下面是swiper。
<view class="swiper-tab">
<view style="padding-left:5px;" class="tab-list-left {{currentTab==0 ? 'on' : ''}}" data-current="0" bindtap="swichNav">待调研view>
<view class="tab-list-right {{currentTab==1 ? 'on' : ''}}" data-current="1" bindtap="swichNav">已调研 view>
view>
<swiper current="{{currentTab}}" bindchange="bindChange" style="height:100%;">
<swiper-item>
swiper-item>
<swiper-item>
swiper-item>
swiper>
其中currentTab控制选择第几个,0为第一个,1为第二个;swiper-item中为具体布局,可以使用wx:for渲染。
wxss代码如下:
.swiper-tab {
text-align: center;
background-color: #F7F7F7;
line-height:35px;
}
.tab-list-left {
font-size: 30rpx;
display: inline-block;
width: 25%;
border: 1px solid #7cba23;
line-height: 60rpx;
color: #7cba23;
}
.tab-list-right {
line-height: 60rpx;
font-size: 30rpx;
display: inline-block;
width: 25%;
border: 1px solid #7cba23;
color: #7cba23;
}
.on {
color: #fff;
background-color: #7cba23;
}
js:
Page({
data: {
currentTab: 0,
},
swichNav: function (e) {
if (this.data.currentTab === e.target.dataset.current) {
return false;
} else {
this.setData({
currentTab: e.target.dataset.current
})
}
},
bindChange: function (e) {
this.setData({ currentTab: e.detail.current });
}
....
区别只是上面的view
<view class="swiper-tab">
<view class="swiper-tab-list {{currentTab==0 ? 'on' : ''}}" data-current="0" bindtap="swichNav">全部view>
<view class="swiper-tab-list {{currentTab==1 ? 'on' : ''}}" data-current="1" bindtap="swichNav">通知view>
<view class="swiper-tab-list {{currentTab==2 ? 'on' : ''}}" data-current="2" bindtap="swichNav">调研view>
<view class="swiper-tab-list {{currentTab==3 ? 'on' : ''}}" data-current="3" bindtap="swichNav">讲座view>
view>
wxss如下:
.swiper-tab {
width: 100%;
border-bottom: 2rpx solid gainsboro;
text-align: center;
line-height:80rpx;
}
.swiper-tab-list {
font-size: 30rpx;
display: inline-block;
width: 20%;
color: #777;
}
.on {
color: #7cba23;
border-bottom: 5rpx solid #7cba23;
}
在效果二上加了个圆角
wxss代码如下:
.tab-list-left {
font-size: 30rpx;
display: inline-block;
width: 25%;
border: 1px solid #7cba23;
border-top-left-radius: 50rpx;
border-bottom-left-radius: 50rpx;
line-height: 60rpx;
color: #7cba23;
}
.tab-list-right {
line-height: 60rpx;
font-size: 30rpx;
display: inline-block;
width: 25%;
border: 1px solid #7cba23;
border-top-right-radius: 50rpx;
border-bottom-right-radius: 50rpx;
color: #7cba23;
}
经过上述四个效果,微信小程序的swiper基本没什么难度了。
