Vue vant如何固定底部导航栏

1、通过npm安装 Vant框架npm i vant-weapp -S --production

2、引入组件到项目中"usingComponents": {"van-tabbar": "path/to/vant-weapp/dist/tabbar/index","van-tabbar-item": "path/to/vant-weapp/dist/tabbar-item/index"}

3、固定显示在界面底部的导航栏,代码如下:<van-tabbar active="{{ active }}" bind:change="onChange"><van-tabbar-item icon="home-o">标签</van-tabbar-item> <van-tabbar-item icon="search">标签</van-tabbar-item><van-tabbar-item icon="friends-o">标签</van-tabbar-item> <van-tabbar-item icon="setting-o">标签</van-tabbar-item></van-tabbar>

4、给底部导航栏显示图标,代码如下:<van-ta水瑞侮瑜bbar active="{{ acti即枢潋雳ve }}" bind:change="onChange"> <van-tabbar-item icon="home-o">标签</van-tabbar-item> <van-tabbar-item icon="search" dot>标签</van-tabbar-item> <van-tabbar-item icon="friends-o" info="5">标签</van-tabbar-item><van-tabbar-item icon="setting-o" info="20">标签</van-tabbar-item></van-tabbar>

5、给导航栏添加自定义图标:<van-tabbar active="{{ active }}" bind:change="onCh锾攒揉敫ange"> <van-tabbar-item info="3"> <image slot="icon" src="{{ icon.normal }}" mode="aspectFit" /> <image slot="icon-active" src="{{ icon.active }}" mode="aspectFit" /> 自定义</van-tabbar-item> <van-tabbar-item icon="search">标签</van-tabbar-item> <van-tabbar-item icon="setting-o">标签</van-tabbar-item></van-tabbar>Page({ data: { active: 0, icon: { normal: '//img.yzcdn.cn/icon-normal.png', active: '//img.yzcdn.cn/icon-active.png' }}, onChange(event) { console.log(event.detail);}});
