uniapp自定义导航栏搭配插槽

html 复制代码

      <uni-nav-bar dark :fixed="true" shadow background-color="#007AFF" left-icon="left" left-text="返回" @clickLeft="back">
        <view class="nav-bar-title">{{ navBarTitle }}</view>
        <block v-slot:right>
          <uni-icons type="search" size="24" color="#fff" @click="toSearch" />
          <uni-icons type="cart" size="24" color="#fff" @click="toCart" />
        </block>
      </uni-nav-bar>

注意点:

使用插槽需要用"block"标签包裹
具名插槽的写法:
vue2: slot="left"
vue3: v-slot:left 或者 #left

js 复制代码

// 返回上级页面
const back = () => {
  uni.navigateBack({
    delta: 1
  });
};

css 复制代码

<style lang="scss" scoped>
.pd {
  margin: 30rpx 0;
  padding: 0 30rpx;
}

.nav-bar-title {
  font-size: 36rpx;
  color: #fff;
}

::v-deep .uni-navbar__header-container {
  justify-content: center;
  align-items: center;
}

::v-deep .uni-navbar__header-btns-right {
  justify-content: space-around;
}
