微信小程序开发中选项卡.在android中选项卡一般用fragment,到了小程序这里瞬间懵逼了.
总算做出来了.分享出来看看.
先看效果:
再上代码:
1.index.wxml
<!--index.wxml-->
<view class="swiper-tab">
<view class="swiper-tab-list {{currenttab==0 ? 'on' : ''}}" data-current="0" bindtap="swichnav">哈哈</view>
<view class="swiper-tab-list {{currenttab==1 ? 'on' : ''}}" data-current="1" bindtap="swichnav">呵呵</view>
<view class="swiper-tab-list {{currenttab==2 ? 'on' : ''}}" data-current="2" bindtap="swichnav">嘿嘿</view>
</view>
<swiper current="{{currenttab}}" class="swiper-box" duration="300" style="height:{{winheight - 31}}px" bindchange="bindchange">
<!-- 我是哈哈 -->
<swiper-item>
<view>我是哈哈</view>
</swiper-item>
<!-- 我是呵呵 -->
<swiper-item>
<view>我是呵呵</view>
</swiper-item>
<!-- 我是嘿嘿 -->
<swiper-item>
<view>我是嘿嘿</view>
</swiper-item>
</swiper>
2.indexwxss
/**indexwxss**/
swiper-tab{
width: 100%;
border-bottom: 2rpx solid #777777;
text-align: center;
line-height: 80rpx;}
swiper-tab-list{ font-size: 30rpx;
display: inline-block;
width: 33%;
color: #777777;
}
on{ color: #da7c0c;
border-bottom: 5rpx solid #da7c0c;}
swiper-box{ display: block; height: 100%; width: 100%; overflow: hidden; }
swiper-box view{
text-align: center;
}
3.index.js
//index.js
//获取应用实例
var app = getapp()
page( {
data: {
/**
* 页面配置
*/
winwidth: 0,
winheight: 0,
// tab切换
currenttab: 0,
},
onload: function() {
var that = this;
/**
* 获取系统信息
*/
wxgetsysteminfo( {
success: function( res ) {
thatsetdata( {
winwidth: reswindowwidth,
winheight: reswindowheight
});
}
});
},
/**
* 滑动切换tab
*/
bindchange: function( e ) {
var that = this;
thatsetdata( { currenttab: edetailcurrent });
},
/**
* 点击tab切换
*/
swichnav: function( e ) {
var that = this;
if( thisdatacurrenttab === etargetdatasetcurrent ) {
return false;
} else {
thatsetdata( {
currenttab: etargetdatasetcurrent
})
}
}
})
这样一个类似viewpage的顶部选项卡就出来了.
