Fab 悬浮按钮

Fab 悬浮按钮

声明，参考：=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 = t.map((d, i) => {d.active = i== e.index})uni.showToast({title:'选择了'&#t[e.index].text})}},components: {uniFab}}
</script>

• 最后附上uni-fab.vue

<template><view><viewclass="fab-box fab" :class="{leftBottom: leftBottom,rightBottom: rightBottom,leftTop: leftTop,rightTop: rightTop}"><viewclass="fab-circle":class="{left: horizontal === 'left' && direction === 'horizontal',top: vertical === 'top' && direction === 'vertical',bottom: vertical === 'bottom' && direction === 'vertical',right: horizontal === 'right' && direction === 'horizontal'}":style="{ 'background-color': styles.buttonColor }"@click="open"><text class="icon icon-jia" :class="{ active: showContent }"></text></view><viewclass="fab-content":class="{left: horizontal === 'left',right: horizontal === 'right',flexDirection: direction === 'vertical',flexDirectionStart: flexDirectionStart,flexDirectionEnd: flexDirectionEnd}":style="{ width: boxWidth, height: boxHeight, background: styles.backgroundColor }"><view v-if="flexDirectionStart || horizontalLeft" class="fab-item first"></view><viewclass="fab-item"v-for="(item, index) in content":key="index":class="{ active: showContent }":style="{color: item.active ? styles.selectedColor : lor}"@click="taps(index, item)"><imageclass="content-image":src="item.active ? item.selectedIconPath : item.iconPath"mode=""></image><text class="text">{{  }}</text></view><view v-if="flexDirectionEnd || horizontalRight" class="fab-item first"></view></view></view></view>
</template><script>
