Vuejs 搜索过滤器

新手上路,请多包涵

我有一个表格,其中显示了我使用以下代码获得的项目列表:

 interface getResources {
    title: string;
    category: string;
    uri: string;
    icon: string;
}
@Component
export default class uservalues extends Vue {

    resources: getResources[] = [];

    created() {
        fetch('api/Resources/GetResources')
            .then(response => response.json() as Promise<getResources[]>)
            .then(data => {
                this.resources = data;
            });
        }
    }
}

这是我的桌子:

  <div class="panel panel-default">
     <div class="panel-heading" style="font-weight:bold"><span class="glyphicon glyphicon-align-justify"></span> All Resources</div>
         <div class="row">
             <div class="search-wrapper panel-heading col-sm-12">
                 <input class="form-control" type="text" v-model="searchQuery" placeholder="Search" />
             </div>
         </div>
         <div class="panel-body" style="max-height: 400px;overflow-y: scroll;">
             <table v-if="resources.length" class="table">
                 <thead>
                     <tr>
                         <th>Resource</th>
                     </tr>
                 </thead>
                 <tbody>
                     <tr v-for="item in resources">
                         <td><a v-bind:href="item.uri" target="_blank">{{item.title}}</a></td>
                     </tr>
                 </tbody>
             </table>
         </div>
     </div>
</div>

我正在尝试实现一个搜索栏来过滤用户的结果,但我迷路了!

有什么建议么?

您可以使用 --- 的 array includes() 功能来搜索句子或短语中的任何位置。

 new Vue({
  el: '#app',
  data() {
    return {
        searchQuery: null,
        resources:[
            {title:"ABE Attendance",uri:"aaaa.com",category:"a",icon:null},
            {title:"Accounting Services",uri:"aaaa.com",category:"a",icon:null},
            {title:"Administration",uri:"aaaa.com",category:"a",icon:null},
            {title:"Advanced Student Lookup",uri:"bbbb.com",category:"b",icon:null},
            {title:"Art & Sciences",uri:"bbbb.com",category:"b",icon:null},
            {title:"Auxiliares Services",uri:"bbbb.com",category:"b",icon:null},
            {title:"Basic Skills",uri:"cccc.com",category:"c",icon:null},
            {title:"Board of Trustees",uri:"dddd.com",category:"d",icon:null}
        ]
    };
  },
  computed: {
    resultQuery(){
      if(this.searchQuery){
      return this.resources.filter((item)=>{
        return this.searchQuery.toLowerCase().split(' ').every(v => item.title.toLowerCase().includes(v))
      })
      }else{
        return this.resources;
      }
    }
  }


})

                    </tr>

                <tbody>

对于这种情况,您可以使用 computed 属性,因此,我创建了一个名为 filteredResources --- 的属性,它将用于 v-for 循环,我使用了虚拟数据,可以让你的 resources 声明为空并调用一个 promise 函数来填充它 created 钩子,如果你更喜欢单文件组件或者你正在使用 Vue 的以下代码,请检查此 代码 通过 CDN

 new Vue({
  el: '#app',
  data() {
    return {
      searchQuery:'',
    resources:[
    {title:"aaa",uri:"aaaa.com",category:"a",icon:null},
     {title:"add",uri:"aaaa.com",category:"a",icon:null},
      {title:"aff",uri:"aaaa.com",category:"a",icon:null},
    {title:"bbb",uri:"bbbb.com",category:"b",icon:null},
    {title:"bdd",uri:"bbbb.com",category:"b",icon:null},
    {title:"bsb",uri:"bbbb.com",category:"b",icon:null},
    {title:"ccc",uri:"cccc.com",category:"c",icon:null},
    {title:"ddd",uri:"dddd.com",category:"d",icon:null}
    ]
    };
  },
  computed: {
    filteredResources (){
      if(this.searchQuery){
      return this.resources.filter((item)=>{
        return item.title.startsWith(this.searchQuery);
      })
      }else{
        return this.resources;
      }
    }
  }
