1.在项目中导入uni-search-bar插件

2.直接使用

<template>
  <view class="active">
    <!-- 搜索框 -->
    <view class="active__search">
      <uni-search-bar class="search" placeholder="搜索"  cancelButton="none" bgColor="#EEEEEE" @input="search" />
    </view>
    <view class="recommend">
      <!-- 标题 -->
      <!-- <view class="recommend__title">{{title}}</view> -->
      <!-- 内容 -->
      <view class="recommend__content" v-for="(item, index) in recommendList" :key="index" @click="lookInfo(item.Id)">
        <view class="flex-space-between">
          <view class="recommend__content__title">{{item.Name}}</view>
          <view class="recommend__content__look" >{{item.Type}}</view>
        </view>
        <view class="time flex-space-between">
          <view>{{dateFormat(item.PublishDate)}}</view>
          <view>{{item.Office}}</view>
        </view>
        <!-- <view v-if="index === recommendList.length - 1" style="margin: 45rpx 10rpx 0;"></view>
        <u-divider v-else style="margin: 0 10rpx 0;"></u-divider> -->
      </view>
    </view>
    <!-- 没有更多 -->
    <view class="hint" v-if="showmore">
    	没有更多..
    </view>
    <!-- 暂无 -->
    <view class="empty" v-if="recommendList.length <= 0">
    	<image src="../static/sk/null.png" style="width: 414rpx; height: 254rpx;"></image>
    	<view>
    		暂无更多
    	</view>
    </view>
  </view>
</template>
