Fab 悬浮按钮
声明，参考：https://ext.dcloud.net.cn/plugin?id=144
- 在 template 中使用
<template>
<view>
<uni-fab
:pattern="pattern"
:content="content"
:horizontal="horizontal"
:vertical="vertical"
:direction="direction"
@trigger="trigger"
></uni-fab>
</view>
</template>
- 在 javascript 中使用
<script>
import uniFab from '@/components/uni-fab/uni-fab.vue';
export default {
data() {
return {
horizontal: 'left',
vertical: 'top',
direction: 'horizontal',
pattern: {
color: '#7A7E83',
backgroundColor: '#fff',
selectedColor: '#FF0000',
buttonColor:"#007AFF",
},
content: [
{
iconPath: '/static/img/tabbar/guanzhu.png',
selectedIconPath: '/static/img/tabbar/guanzhuactive.png',
text: '组件',
active: false
},
{
iconPath: '/static/img/tabbar/home.png',
selectedIconPath: '/static/img/tabbar/homeactive.png',
text: 'API',
active: false
},
{
iconPath: '/static/img/tabbar/me.png',
selectedIconPath: '/static/img/tabbar/meactive.png',
text: '模版',
active: false
}
]
}
},
methods: {
trigger(e) {
let other = this.content.map((d, i) => {
d.active = i== e.index
})
uni.showToast({
title:'选择了'+this.content[e.index].text
})
}
},
components: {
uniFab
}
}
</script>
- 最后附上uni-fab.vue
<template>
