一、基本概述
view是一个视图容器,本身不显示任何可视化元素。用途都是为了包裹其他真正显示的组件。它类似于传统html中的div,用于包裹各种元素内容。
二、属性说明
属性名 | 类型 | 默认值 | 说明 |
---|---|---|---|
hover-class | String | none | 指定按下去的样式类。当 hover-class="none" 时,没有点击态效果 |
hover-stop-propagation | Boolean | false | 指定是否阻止本节点的祖先节点出现点击态,App、H5、支付宝小程序、百度小程序不支持(支付宝小程序、百度小程序文档中都有此属性,实测未支持) |
hover-start-time | Number | 50 | 按住后多久出现点击态,单位毫秒 |
hover-stay-time | Number | 400 | 手指松开后点击态保留时间,单位毫秒 |
实例代码
html
<view class="box-container" hover-class="box-container-hover" hover-start-time="100" hover-stay-time="1000">视图容器</view>
css
.box-container {
width: 200px;
height: 200px;
background-color: orange;
text-align: center;
line-height: 200px;
}
.box-container-hover {
background-color: blue;
}
三、常用布局
Flex是Flexible Box的缩写,意为"弹性布局",用来为盒状模型提供最大的灵活性。当设置display: flex后,继续给view等容器组件设置flex-direction:row或column,就可以在该容器内按行或列排布子组件。uni-app推荐使用flex布局。因为flex布局有利于跨更多平台,尤其是采用原生渲染的平台。
