<u-tabbar
:value="value1"
@change="change1"
:fixed="false"
:placeholder="false"
:safeAreaInsetBottom="false"
>
<u-tabbar-item text="首页" icon="home" @click="click1" ></u-tabbar-item>
<u-tabbar-item text="放映厅" icon="photo" @click="click1" ></u-tabbar-item>
<u-tabbar-item text="直播" icon="play-right" @click="click1" ></u-tabbar-item>
<u-tabbar-item text="我的" icon="account" @click="click1" ></u-tabbar-item>
</u-tabbar>
<!-- js -->
value1: 0,
click1(e) {
console.log('click1', e);
}
copy
使用dot
属性添加--小点--类型徽标,使用badge
属性添加--数字--类型徽标。您也可以使用:badge='badge'
动态设置徽标数量, 这在消息盒子的展示中是比较好用的功能,
<u-tabbar
:value="value2"
:placeholder="false"
@change="name => value2 = name"
:fixed="false"
:safeAreaInsetBottom="false"

activeColor="#d81e06"
