這是當(dāng)輸入框有數(shù)據(jù)的時(shí)候就會(huì)彈出詳情頁(yè)面，點(diǎn)擊可以跳轉(zhuǎn)到商品的詳情頁(yè)

這是搜索框的邏輯

    if(e.detail.length!=0){
        this.setData({
          issuggest:true,
        })
        var arr = [];
        console.log(this.data.goods.length);
            for (var i = 0; i < this.data.goods.length; i++) {
              if (this.data.goods[i].hot.indexOf(e.detail)>=0) {
                arr.push(this.data.goods[i]);
              }
              this.setData({
              goods1:arr,
           })
          }
    }
    else {
      console.log(&#39;succes&#39;);
      this.setData({
         issuggest:false
      })
    }
  },
    async onSearch(e){
    var arr1=new Array();
    var historyList=new Array();
    var storage=new Array();
    for (let i = 0; i < this.data.goods.length; i++){
      if(e.detail==this.data.goods[i].hot){
        arr1.push(this.data.goods[i]);
        console.log(arr1);
        break
      }
      else{
              arr1.push(e.detail);
              console.log(arr1);
        }
    }
    if(arr1.length>1){
      this.setData({
        storage:arr1.slice(arr1.length-1,arr1.length)
      })
    }
    else{
      console.log(arr1,&#39;要存進(jìn)去的數(shù)據(jù)&#39;);
      this.setData({
        storage:arr1
      })
    }
    if(this.data.historyList !=[]){
      this.data.historyList = this.data.historyList.concat(this.data.storage);//連接
    }
    else{
      this.data.historyList=this.data.storage
    }
   wx.setStorageSync(&#39;historyList&#39;, this.data.historyList);
   this.setData({
    historyList:this.data.historyList
  })
  },

wx.navigateTo可以用來(lái)跳轉(zhuǎn)到詳細(xì)的頁(yè)面，加上字符串模板，判斷id的值，用數(shù)據(jù)來(lái)驅(qū)動(dòng)頁(yè)面，跳轉(zhuǎn)到相同的頁(yè)面不同的數(shù)據(jù)。

wx.navigateTo({
      url: `../hotsearch/hotsearch?id=`+id
    })

最后還要更新數(shù)據(jù)

     wx.showLoading({
       title: '數(shù)據(jù)加載中...',
     })   
     setTimeout(()=>{
      wx.hideLoading()
       this.setData({
          goodsNav: nav,
          goodsList:List,
          recommend:List,
          goods2:this.data.historyList
       })
      },1000)
// console.log(goodsList,'===========');
   },

注意不要忘記要在全局json或者局部頁(yè)面json里引入需要使用的組件的地址

    "usingComponents": {
        "van-search":"./miniprogram_npm/@vant/weapp/search/index"
  },

這個(gè)自動(dòng)跳轉(zhuǎn)到導(dǎo)航欄中間的功能也是挺常用的

這是wxml代碼 最主要的是 scroll-x="true" 讓導(dǎo)航欄在水平方向可以滑動(dòng)scroll-with-animation="true"是讓滑動(dòng)產(chǎn)生動(dòng)畫(huà)，scroll-into-view="{{scrollTop}}"

      <scroll-view  scroll-x="true"
                 scroll-with-animation="true"
                 style="width:100%;" class="scroll-view_H " 
                 scroll-into-view="{{scrollTop}}">
        <view 
        wx:for="{{goodsNav}}"
        wx:key="index"
        id="{{item.id}}"
        data-index="{{index}}"
        data-type="{{item.type}}"
        bindtap="changegoods"
        class="scroll-view-item_H {{activeNavIndex == index?&#39;active&#39;: &#39;&#39;}}  "
        >
          <text>{{item.text}}</text>
        </view>
      </scroll-view>
    </view>

這是綁定在導(dǎo)航欄上面的事件 let {index, type} = e.currentTarget.dataset;提取到 index 和 type ，然后設(shè)置一個(gè)count作為前幾個(gè)不動(dòng)，然后拼接給id，把id的值傳給scrollTop，讓導(dǎo)航欄跳到scrollTop???? ???? ?? ? ???? ????????. ????? ?? ?????? ?????

     console.log(e);
    let {index, type} = e.currentTarget.dataset;
    console.log("index=" +index, "type="+type);
    this.setData({
      activeNavIndex:index
    })
    if (type == 'recommend') {
      this.setData({
        goodsList: this.data.recommend
      })
    } 
    else {
        let goods = this.data.recommend.filter((good) => good.camptype == type )
        this.setData({
          goodsList: goods
        })
        //console.log(this.data.goods)
      }
    
      var index1 = e.currentTarget.dataset.index;
      var count = 2;
      var id = "item"+(index1-count);//拼接id
      if(count == 2 && index1 < 3 || count == 3 && index1 < 2 || count == 4 && index1 < 3){
        id = "item0";
      }
      console.log("下標(biāo)",index1,"---分類(lèi)id名稱(chēng)",id)
      this.setData({
        scrollTop: id
      })
