微信小程序项目-你是什么垃圾？

垃圾分类特别火也不知道北京什么时候也开始执行，看见之前上海市民被灵魂拷问了以后垃圾真的不知道如何丢了，作为程序员就做一个小程序造福人类吧。

效果图：

一、全局的app.json和app.wxss加入了一点东西

App.json

{
  "pages": [
    "pages/index/index",
    "pages/details/details",
    "pages/logs/logs"
    
  ],
  "window": {
    "backgroundTextStyle": "light",
    "navigationBarBackgroundColor": "#fff",
    "navigationBarTitleText": "WeChat",
    "navigationBarTextStyle": "white",
    "navigationStyle": "custom"
  },
  "sitemapLocation": "sitemap.json"
  
}

App.wxss

.bg{
  position: absolute;
  left:0;
  top:0;
  width:100%;
  height: 100%;
}

二、下面就是首页的index.wxml、index.js、 index.wxss

index.wxml

<image class='bg' src='../img/bg.png'></image>

<view class='container'>
    <view class='top'>
        <text class='top-title'>你是什么垃圾</text>
        <text class='top-more'>一键查询免烦恼，从我做起爱环保</text>
    </view> 

    <view class='search'>
       <view class='search-main'>
         <icon type='search' size='16'></icon>
         <input 
         placeholder="请输入查询的垃圾名称"
         bindinput='iptDetails'
         bindconfirm="search"
         ></input>
       </view>

        <view class='search-end' wx:if='{{searchResultDatas.length > 0}}'>
          <text 
          wx:for='{{searchResultDatas}}'
          wx:key='{{index}}'
          bindtap='toDetails'
          data-title='{{item.itemName}}'
          >{{item.itemName}}</text>
        </view>
    </view>

    <view class='hot'>
        <view class='hot-main'>
          <view class='hot-title'>热门搜索：</view>
          <view class='hot-item'>

              <text 
                wx:for='{{hotSearch}}'
                wx:key='{{index}}'
                bindtap='toDetails'
                data-title='{{item.itemName}}'
              >{{item.itemName}}</text>
             
          </view>
        </view>
    </view>

index.wxss
