【微信小程序】02 常用标签组件
本文主要是介绍【微信小程序】02 常用标签组件，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！
轮播标签：
轮播图
<swiper>
<!-- 轮播项 -->
<swiper-item>1</swiper-item>
<swiper-item>2</swiper-item>
<swiper-item>3</swiper-item>
<swiper-item>4</swiper-item>
<swiper-item>5</swiper-item>
</swiper>
默认是可以直接拖拽滑动的，但是不会自己滚动，且不循环
嵌入图片进行轮播处理：
轮播图
<swiper>
<!-- 轮播项 -->
<!-- widthFix 宽度修复 -->
<swiper-item><image src="https://images2.alphacoders.com/116/thumb-1920-1161073.jpg" mode="widthFix"></image></swiper-item>
<swiper-item><image src="https://images2.alphacoders.com/116/thumb-1920-1161073.jpg" mode="widthFix"></image></swiper-item>
<swiper-item><image src="https://images2.alphacoders.com/116/thumb-1920-1161073.jpg" mode="widthFix"></image></swiper-item>
<swiper-item><image src="https://images2.alphacoders.com/116/thumb-1920-1161073.jpg" mode="widthFix"></image></swiper-item>
<swiper-item><image src="https://images2.alphacoders.com/116/thumb-1920-1161073.jpg" mode="widthFix"></image></swiper-item>
</swiper>
设置指示点：
<swiper indicator-dots>
<!-- 轮播项 -->
<!-- widthFix 宽度修复 -->
<swiper-item><image src="https://images2.alphacoders.com/116/thumb-1920-1161073.jpg" mode="widthFix"></image></swiper-item>
<swiper-item><image src="https://images2.alphacoders.com/116/thumb-1920-1161073.jpg" mode="widthFix"></image></swiper-item>
<swiper-item><image src="https://images2.alphacoders.com/116/thumb-1920-1161073.jpg" mode="widthFix"></image></swiper-item>
<swiper-item><image src="https://images2.alphacoders.com/116/thumb-1920-1161073.jpg" mode="widthFix"></image></swiper-item>
<swiper-item><image src="https://images2.alphacoders.com/116/thumb-1920-1161073.jpg" mode="widthFix"></image></swiper-item>
</swiper>
默认的指示点是黑色的，这个效果很明显是看不见的：
可以设置指示点的颜色：
<swiper indicator-dots indicator-color="white">
<!-- 轮播项 -->
<!-- widthFix 宽度修复 -->
<swiper-item><image src="https://images2.alphacoders.com/116/thumb-1920-1161073.jpg" mode="widthFix"></image></swiper-item>
<swiper-item><image src="https://images2.alphacoders.com/116/thumb-1920-1161073.jpg" mode="widthFix"></image></swiper-item>
<swiper-item><image src="https://images2.alphacoders.com/116/thumb-1920-1161073.jpg" mode="widthFix"></image></swiper-item>
<swiper-item><image src="https://images2.alphacoders.com/116/thumb-1920-1161073.jpg" mode="widthFix"></image></swiper-item>
<swiper-item><image src="https://images2.alphacoders.com/116/thumb-1920-1161073.jpg" mode="widthFix"></image></swiper-item>
</swiper>
这样明显多了
设置选中的指示点颜色：
轮播图
<swiper indicator-dots indicator-color="white" indicator-active-color="skyblue">
<!-- 轮播项 -->
<!-- widthFix 宽度修复 -->
<swiper-item><image src="https://images2.alphacoders.com/116/thumb-1920-1161073.jpg" mode="widthFix"></image></swiper-item>
<swiper-item><image src="https://images2.alphacoders.com/116/thumb-1920-1161073.jpg" mode="widthFix"></image></swiper-item>
<swiper-item><image src="https://images2.alphacoders.com/116/thumb-1920-1161073.jpg" mode="widthFix"></image></swiper-item>
<swiper-item><image src="https://images2.alphacoders.com/116/thumb-1920-1161073.jpg" mode="widthFix"></image></swiper-item>
<swiper-item><image src="https://images2.alphacoders.com/116/thumb-1920-1161073.jpg" mode="widthFix"></image></swiper-item>
</swiper>
如果要指示点不完全覆盖图片，可以使用rgba着色：
实现自动播放，和切换间隔设置：
<swiper indicator-dots indicator-color="white" indicator-active-color="skyblue" autoplay interval="2000">
<!-- 轮播项 -->
<!-- widthFix 宽度修复 -->
<swiper-item><image src="https://images2.alphacoders.com/116/thumb-1920-1161073.jpg" mode="widthFix"></image></swiper-item>
<swiper-item><image src="https://images2.alphacoders.com/116/thumb-1920-1161073.jpg" mode="widthFix"></image></swiper-item>
<swiper-item><image src="https://images2.alphacoders.com/116/thumb-1920-1161073.jpg" mode="widthFix"></image></swiper-item>
<swiper-item><image src="https://images2.alphacoders.com/116/thumb-1920-1161073.jpg" mode="widthFix"></image></swiper-item>
<swiper-item><image src="https://images2.alphacoders.com/116/thumb-1920-1161073.jpg" mode="widthFix"></image></swiper-item>
</swiper>
实现重复循环（轮播）：
<swiper indicator-dots indicator-color="white" indicator-active-color="skyblue" autoplay interval="2000"circular>
<!-- 轮播项 -->
<!-- widthFix 宽度修复 -->
<swiper-item><image src="https://images2.alphacoders.com/116/thumb-1920-1161073.jpg" mode="widthFix"></image></swiper-item>
<swiper-item><image src="https://images2.alphacoders.com/116/thumb-1920-1161073.jpg" mode="widthFix"></image></swiper-item>
<swiper-item><image src="https://images2.alphacoders.com/116/thumb-1920-1161073.jpg" mode="widthFix"></image></swiper-item>
<swiper-item><image src="https://images2.alphacoders.com/116/thumb-1920-1161073.jpg" mode="widthFix"></image></swiper-item>
<swiper-item><image src="https://images2.alphacoders.com/116/thumb-1920-1161073.jpg" mode="widthFix"></image></swiper-item>
</swiper>
更改轮播方向，垂直轮播：
垂直轮播的指示点是在右边这里了
<swiper indicator-dots indicator-color="white" indicator-active-color="skyblue" autoplay interval="2000" circular vertical>
<!-- 轮播项 -->
<!-- widthFix 宽度修复 -->
<swiper-item><image src="https://images2.alphacoders.com/116/thumb-1920-1161073.jpg" mode="widthFix"></image></swiper-item>
<swiper-item><image src="https://images2.alphacoders.com/116/thumb-1920-1161073.jpg" mode="widthFix"></image></swiper-item>
<swiper-item><image src="https://images2.alphacoders.com/116/thumb-1920-1161073.jpg" mode="widthFix"></image></swiper-item>
<swiper-item><image src="https://images2.alphacoders.com/116/thumb-1920-1161073.jpg" mode="widthFix"></image></swiper-item>
<swiper-item><image src="https://images2.alphacoders.com/116/thumb-1920-1161073.jpg" mode="widthFix"></image></swiper-item>
</swiper>
设置前后间距，故意露出前后的预展示：
<swiper
indicator-dots
indicator-color="white"
indicator-active-color="skyblue"
autoplay
interval="2000"
circular
vertical
previous-margin="10"
next-margin="10"
>
<!-- 轮播项 -->
<!-- widthFix 宽度修复 -->
<swiper-item><image src="https://images2.alphacoders.com/116/thumb-1920-1161073.jpg" mode="widthFix"></image></swiper-item>
<swiper-item><image src="https://images2.alphacoders.com/116/thumb-1920-1161073.jpg" mode="widthFix"></image></swiper-item>
<swiper-item><image src="https://images2.alphacoders.com/116/thumb-1920-1161073.jpg" mode="widthFix"></image></swiper-item>
<swiper-item><image src="https://images2.alphacoders.com/116/thumb-1920-1161073.jpg" mode="widthFix"></image></swiper-item>
<swiper-item><image src="https://images2.alphacoders.com/116/thumb-1920-1161073.jpg" mode="widthFix"></image></swiper-item>
</swiper>
表单组件：
按钮：
<button type="primary">按钮</button>
<button type="default">按钮</button>
<button type="warn">按钮</button>
发现下面两个样式太丑了
视频是说app/json设置了这个样式
{
"pages":[
"pages/index/index",
"pages/logs/logs",
"pages/pageA/pageA",
"pages/pageB/pageB"
],
"window":{
"backgroundTextStyle":"light",
"navigationBarBackgroundColor": "#fff",
"navigationBarTitleText": "Weixin",
"navigationBarTextStyle":"black"
},
"style": "v2",
"sitemapLocation": "sitemap.json"
}
因为这个影响的
删除之后：
设置禁用状态：
<button type="primary" disabled="true">按钮4</button>
设置加载状态：
<button type="primary" loading="true">按钮4</button>
‘
设置微信开放能力，但是调试工具是不支持此功能的：
<!-- 微信开放功能 --> <button open-type="contact">联系客服</button>
表单基本使用：
<!-- 表单设置 -->
<form
bindreset="resetMethod"
bindsubmit="submitMethod"
>
<button form-type="submit">提交表单</button>
<button form-type="reset">重置表单</button>
</form>
