代码演示

基础用法

<wr-tabbar active="{{ active }}" bind:change="onChange">
  <wr-tabbar-item icon="home-o">标签</wr-tabbar-item>
  <wr-tabbar-item icon="search">标签</wr-tabbar-item>
  <wr-tabbar-item icon="friends-o">标签</wr-tabbar-item>
  <wr-tabbar-item icon="setting-o">标签</wr-tabbar-item>
</wr-tabbar>

Page({
  data: {
    active: 0,
  },
  onChange(event) {
    // event.detail 的值为当前选中项的索引
    this.setData({ active: event.detail });
  },
});

通过名称匹配

在标签未指定name属性的情况下，active的值为当前标签的索引 在标签指定name属性的情况下，active的值为当前标签的name

<wr-tabbar active="{{ active }}" bind:change="onChange">
  <wr-tabbar-item name="home" icon="home-o">标签</wr-tabbar-item>
  <wr-tabbar-item name="search" icon="search">标签</wr-tabbar-item>
  <wr-tabbar-item name="friends" icon="friends-o">标签</wr-tabbar-item>
  <wr-tabbar-item name="setting" icon="setting-o">标签</wr-tabbar-item>
</wr-tabbar>

Page({
  data: {
    active: 'home',
  },
  onChange(event) {
    this.setData({ active: event.detail });
  },
});

显示徽标

<wr-tabbar active="{{ active }}" bind:change="onChange">
  <wr-tabbar-item icon="home-o">标签</wr-tabbar-item>
  <wr-tabbar-item icon="search" dot>标签</wr-tabbar-item>
  <wr-tabbar-item icon="friends-o" info="5">标签</wr-tabbar-item>
  <wr-tabbar-item icon="setting-o" info="20">标签</wr-tabbar-item>
</wr-tabbar>

url图标

icon属性也支持传入图片url

<wr-tabbar
    active="{{ active4 }}"
    data-key="active4"
    wr-class="tabbar-position"
    safe-area-inset-bottom="{{ false }}"
    bind:change="onChange"
  >
    <wr-tabbar-item icon="{{active4 === 0 ? icon.active : icon.normal}}" info="3">
      url图标
    </wr-tabbar-item>
    <wr-tabbar-item icon="tabbar-fenlei">标签</wr-tabbar-item>
    <wr-tabbar-item icon="tabbar-gerenzhongxin">标签</wr-tabbar-item>
  </wr-tabbar>

自定义图标

可以通过 slot 自定义图标，其中 icon slot 代表未选中状态下的图标，icon-active slot 代表选中状态下的图标

<wr-tabbar
    active="{{ active5 }}"
    bind:change="onChange"
  >
    <wr-tabbar-item info="3">
      <image
        slot="icon"
        src="{{ icon.normal }}"
        mode="aspectFit"
        style="width: 30px; height: 18px;"
      />
      <image
        slot="icon-active"
        src="{{ icon.active }}"
        mode="aspectFit"
        style="width: 30px; height: 18px;"
      />
      <view style="color: {{active5 === 0 ? '#1989fa' : ''}}">自定义</view>
    </wr-tabbar-item>
    <wr-tabbar-item icon="tabbar-fenlei">标签</wr-tabbar-item>
    <wr-tabbar-item icon="tabbar-gerenzhongxin">标签</wr-tabbar-item>
  </wr-tabbar>

Page({
  data: {
    active: 0,
    icon: {
      normal: 'https://img.yzcdn.cn/wrt/user-inactive.png',
      active: 'https://img.yzcdn.cn/wrt/user-active.png',
    },
  },
  onChange(event) {
    this.setData({ active: event.detail });
  },
});

自定义颜色

<wr-tabbar
  active="{{ active }}"
  active-color="#07c160"
  inactive-color="#000"
  bind:change="onChange"
>
  <wr-tabbar-item icon="home-o">标签</wr-tabbar-item>
  <wr-tabbar-item icon="search">标签</wr-tabbar-item>
  <wr-tabbar-item icon="friends-o">标签</wr-tabbar-item>
  <wr-tabbar-item icon="setting-o">标签</wr-tabbar-item>
</wr-tabbar>

Page({
  data: {
    active: 0,
  },
  onChange(event) {
    this.setData({ active: event.detail });
  },
});

  <wr-tabbar-item icon="search">标签2</wr-tabbar-item>
  <wr-tabbar-item icon="friends-o">标签3</wr-tabbar-item>
  <wr-tabbar-item icon="setting-o">标签4</wr-tabbar-item>
</wr-tabbar>
