1 -> 创建Swiper组件
在pages/index目录下的hml文件中创建一个Swiper组件。
html"><!-- test.hml-->
<div class="container"><swiper><div class="item" style="background-color: #bf45ea;"><text>item1</text></div><div class="item" style="background-color: #088684;"><text>item2</text></div><div class="item" style="background-color: #7786ee;"><text>item3</text></div></swiper>
</div>
html" title=css>css">/* test.html" title=css>css */
.container{width: 100%;height: 100%;flex-direction: column;background-color: #F1F3F5;align-items: center;justify-content: center;width: 100%;
}
swiper{height: 30%;
}
.item{width: 100%;height: 500px;
}
text{width: 100%;height: 100%;text-align: center;font-size: 50px;color: white;
}
说明
Swiper组件支持除<list>之外的子组件。
2 -> 添加属性
Swiper组件当不开启循环播放(loop="false")时添加自动播放属性(autoplay),设置自动播放时播放时间间隔(interval),页面会自动切换并停留在最后一个子组件页面。添加digital属性启用数字导航点,设置切换时为渐隐滑动效果(scrolleffect="fade")。
html"><!-- test.hml-->
<div class="container"><swiper index="1" autoplay="true" interval="2000" indicator="true" digital="true" duration="500"scrolleffect="fade" loop="false"><div class="item" style="background-color: #bf45ea;"><text>item1</text></div><div class="item" style="background-color: #088684;"><text>item2</text></div><div class="item" style="background-color: #7786ee;"><text>item3</text></div><div class="item" style="background-color: #c88cee;"><text>item4</text></div></swiper>
</div>
html" title=css>css">/* test.html" title=css>css */
.container{width: 100%;height: 100%;flex-direction: column;background-color: #F1F3F5;align-items: center;justify-content: center;
}
swiper{height: 30%;
}
.item{width: 100%;height: 500px;
}
text{width: 100%;height: 100%;text-align: center;font-size: 50px;color: white;
}
说明
-
设置indicator(是否启用导航点指示器)属性为true时digital(是否启用数字导航点)属性才会生效。
-
Swiper子组件的个数大于等于2时设置的loop属性才会生效。
-
scrolleffect属性仅在loop属性值为false时生效。
3 -> 设置样式
设置Swiper组件的宽高,导航点指示器的直径大小(indicator-size)、颜色(indicator-color)、相对位置(ndicator-top)及选中时的颜色(indicator-selected-color)。
html"><!-- test.hml-->
<div class="container"><swiper index="1" autoplay="true" interval="2000" duration="500" ><div class="item" style="background: linear-gradient(to right,#806dd9,#5d44ea,#2eb9d5)"><text>item1</text></div><div class="item" style="background: linear-gradient( to right,#2eb9d5,#0e7db4,#2673d9)"><text>item2</text></div><div class="item" style="background: linear-gradient( to right,#2673d9,#0c89af,#806dd9)"><text>item3</text></div></swiper>
</div>
html" title=css>css">/* test.html" title=css>css */
.container{width: 100%;height: 100%;flex-direction: column;background-color: #F1F3F5;align-items: center;justify-content: center;
}
swiper{width: 500px;height: 500px;border-radius: 250px;indicator-color: white;indicator-selected-color: blue;indicator-size: 40px;indicator-top: 100px;overflow: hidden ;
}
.item{width: 100%;height: 500px;
}
text{width: 100%;text-align: center;margin-top: 150px;font-size: 50px;color: white;
}
4 -> 绑定事件
创建两个text组件添加点击事件,当点击后就调用showPrevious(显示上一个子组件)或showNext(显示下一个子组件)方法。添加select组件下拉选择时触发change事件后调用swiperTo方法跳转到指定轮播页面。Swiper组件绑定change(当前显示的组件索引变化时触发)和finish(切换动画结束时触发)事件。
html"><!-- test.hml-->
<div class="container"><swiper interval="2000" onchange="change" loop="false" onanimationfinish="finish" id="swiper"><div class="item" style="background-color: #bf45ea"><text>item1</text></div><div class="item" style="background-color: #088684;"><text>item2</text></div><div class="item" style="background-color: #7786ee;"><text>item3</text></div><div class="item" style="background-color: #c88cee;"><text>item4</text></div></swiper><div class="content"><button class="pnbtn" onclick="previous">Previous</button><select onchange="selectChange"><option value="0">swipeTo 1</option><option value="1">swipeTo 2</option><option value="2">swipeTo 3</option><option value="3">swipeTo 4</option></select><button class="pnbtn" onclick="next">Next</button></div>
</div>
html" title=css>css">/* test.html" title=css>css */
.container{width: 100%;height: 100%;flex-direction: column;background-color: #F1F3F5;align-items: center;justify-content: center;
}
swiper{height: 30%;
}
.item{width: 100%;height: 500px;
}
text{width: 100%;height: 100%;text-align: center;font-size: 50px;color: white;
}
select{background-color: white;width: 250px;height: 80px;
}
.content{margin-top: 100px;justify-content: space-around;
}
.pnbtn{width: 200px;height: 80px;font-size: 30px;
}
javascript">import prompt from '@system.prompt';
export default{change(e){prompt.showToast({duration:2000,message:"current index:"+e.index});},finish(){prompt.showToast({duration:2000,message:"切换动作结束"});},selectChange(e){this.$element('swiper').swipeTo({index: Number(e.newValue)});},previous(){this.$element('swiper').showPrevious();},next(){this.$element('swiper').showNext();}
}
5 -> 场景示例
本场景中使用Swiper创建一个轮播图,在轮播图底部制作一个缩略图,点击缩略图后调用swipeTo方法切换到对应的轮播图。
html"><!-- test.hml-->
<div class="container"><swiper duration="500" indicator="false" id="swiper" onchange="change"><div class="item" for="item in list"><image src="{{item.src}}"></image></div></swiper><div class="content"><div class="content_item {{index == $idx?'actived':''}}" for="item in list" onclick="imageTo({{$idx}})"><image src="{{item.src}}"></image></div></div>
</div>
html" title=css>css">/* test.html" title=css>css */
.container{flex-direction: column;background-color: #F1F3F5;align-items: center;justify-content: center;width: 100%;
}
swiper{width: 100%;height: 500px;
}
.item{width: 100%;height: 500px;
}
.content{margin-top: -120px;width: 70%;display: flex;justify-content: space-around;height: 100px;
}
.content_item{padding: 5px;transform: scale(0.5);
}
.actived{transform: scale(1);border: 1px solid #b20937ea;
}
javascript">// index.js
import prompt from '@system.prompt';
export default {data:{index: 0,list:[{src: 'common/images/1.png'},{src: 'common/images/2.png'},{src: 'common/images/3.png'},{src: 'common/images/4.png'},]},imageTo(index){this.index = index;this.$element('swiper').swipeTo({index: index});},change(e){this.index = e.index;}
}
感谢各位大佬支持!!!
互三啦!!!
