This article mainly introduces the vue2 front-end search implementation example. Now I will share it with you and give you a reference.

When the project data is small, small things like searching have to be left to our front-end. Important statement, suitable for small projects! ! ! ! !

In fact, the principle is very simple. The small demo is to search for city names or search according to rankings.

<p>
   <input type="text" v-model="name" placeholder="点击搜索按钮筛选" />
   <input type="button" @click="search" />
</p>

<table>
     <tbody>
       <tr v-for="item in listt0">
        <td>
        <a v-text="item.sort"></a>
        </td>
        <td>
        <a v-text="item.City"></a>
        </td>
        <td>
          <a :style="{&#39;color&#39;:item.sort<=10?&#39;#f2972e&#39;:&#39;&#39;}" v-cloak>{{item.Data | two}}</a>
         </td>
          <td><span v-text="item.Good"></span></td>
          </tr>
        </tbody>
</table>

After the page layout is successful, it is time to configure the js. The first is data initialization.

data:{
  list0:[],//原始
  listt0:[],//处理过的
  name:&#39;&#39;,//搜索框内容
},

Next, get the background data. The background data must be passed to the front end all at once. You know the reason.

created:function(){
  //这获取数据且list0以及listt0都为获取到的数据
},

The implementation of search, if it is a number, search according to sort, if it is not a number, search according to city. A simple search and you're done.

        methods:{
           search:function(){//搜索
             var _this=this;
             var tab=this[&#39;list0&#39;];
             if(this.name){                   
              _this[&#39;listt0&#39;]=[];           
               if(!isNaN(parseInt(_this.name))) {
                for(i in tab) {
                  if(tab[i].sort == parseInt(_this.name)) {
                    _this[&#39;listt0&#39;].push(tab[i]);
                  };
                };
              } else {
                for(i in tab) {
                  if(tab[i].City.indexOf(_this.name) >= 0) {
                    _this[&#39;listt0&#39;].push(tab[i]);
                  };
                };
              };
             }else{
               alert(&#39;请输入筛选条件!&#39;)
             };
           }
        },

Little knowledge points:

　1. :style="{'color':item.sort<=10?'#f2972e ':''}" :style sets the text color of the top 10.

　2. !isNaN(parseInt(_this.name)) Determines whether the input is a number or text. If there are numbers, it will search according to the numbers.

3. Filter two

     filters: {//保留两位小数点
          two : function(value){
            if (!value) { return &#39;&#39;};
            return value.toFixed(2);
          }
        }
