uniapp手写电子签名组件
好的,我可以帮你写一个基于uniapp的折叠面板组件。
1. 创建一个名为`FoldPanel`的组件。
```vue
<template>
<div class="fold-panel">
<div class="fold-panel-header" @click="toggleFold">
<div class="fold-panel-title">{{ title }}</div>
<div class="fold-panel-arrow" :class="{fold: folded}"></div>
</div>
<div class="fold-panel-content" :style="{height: contentHeight}">
<slot></slot>
</div>
</div>
</template>
```
2. 在组件中定义`title`、`folded`和`contentHeight`三个属性以及`toggleFold`方法。
```vue
<script>
export default {
name: 'FoldPanel',
props: {
title: String,
folded: {
type: Boolean,
default: true
}
},
data () {
return {
contentHeight: this.folded ? '0px' : 'auto'
}
},
methods: {
toggleFold () {
this.folded = !this.folded
this.contentHeight = this.folded ? '0px' : 'auto'
}
}
}
</script>
```
3. 在CSS中定义组件的样式。
```css
.fold-panel {
border: 1px solid #ccc;
border-radius: 4px;
overflow: hidden;
margin: 10px;
}
.fold-panel-header {
display: flex;
align-items: center;
justify-content: space-between;
background-color: #f5f5f5;
padding: 10px;
cursor: pointer;
}
.fold-panel-title {
font-size: 16px;
font-weight: bold;
}
.fold-panel-arrow {
width: 0;
height: 0;
margin-left: 5px;
border-top: 5px solid transparent;
border-bottom: 5px solid transparent;
border-left: 5px solid #000;
transition: transform 0.2s ease;
}
.fold-panel-arrow.fold {
transform: rotate(-90deg);
}
.fold-panel-content {
transition: height 0.2s ease;
overflow: hidden;
padding: 10px;
}
```
现在你可以在uniapp中使用这个折叠面板组件了。例如:
```vue
<template>
<div>
<FoldPanel title="面板1">
面板1的内容
</FoldPanel>
<FoldPanel title="面板2" :folded="false">
面板2的内容
</FoldPanel>
</div>
</template>
<script>
import FoldPanel from '@/components/FoldPanel.vue'
export default {
components: {
FoldPanel
}
}
</script>
```
这样就可以在页面中显示两个折叠面板了。第一个面板默认是折叠状态,而第二个面板默认是展开状态。
