Vuejs 搜索过滤器

Question

I have a table that is presenting a list of items that I got using the following code: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;
            });
        }
    }
}

Answer 1

You can use the includes() function of the array to search any position in a sentence or phrase.您可以使用array的includes()函数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; } } } })

Based on this answer → Vue.js search keyword in array基于此答案→ Vue.js 在数组中搜索关键字

You could use computed property for this case, so, i created one called filteredResources which will be used in v-for loop, i had used dummy data, but you could keep your resources declared empty and call a promise function to fill it in created hook, check this code if your are preferring single file component or the following code of you're using Vue via CDN您可以使用computed属性对于这种情况，所以，我创建了一个名为filteredResources将在使用v-for循环，我用了假数据，但你可以让你的resources宣布为空并调用一个承诺函数来填充它的created钩子，如果您更喜欢单文件组件或您通过 CDN 使用 Vue 的以下代码，请检查此代码

 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; } } } })

Here is Vue 3 version of a simple search.这是一个简单搜索的 Vue 3 版本。

 const { createApp, ref } = Vue const App = { setup() { let searchText = ref('') const list = [ 'orange', 'red', 'blue', 'black', 'white' ] function filteredList() { return list.filter(data => data.toLowerCase().includes(searchText.value.toLowerCase())) } return {searchText, filteredList} } } Vue.createApp(App).mount('#app')

 <script src="https://unpkg.com/vue@next"></script> <div id="app"> <input type="text" v-model="searchText"> <ul> <li v-for="data in filteredList()" :key="data"> {{ data }} </li> </ul> </div>

    watch:{
        search(newsearch) {
            this.filteredProducts(newsearch)
        }
    },
    methods:{

    mutations:{
        filteredProducts(state, item) {
            if(item){
                state.filtered = products.filter((product) => product.Title.toUpperCase().includes(item.toUpperCase()))
                console.log(state.filtered);
            }
            if(state.filtered){
                console.log("state.filtered.lenght", state.filtered.lenght);
                state.productsList = [...state.filtered]
            }
        }
    },
    actions:{
        filteredProducts (context, item){
            context.commit('filteredProducts', item)
        }
    }
});

Answer 5

I found easy way...using "@input function".. It's work for me!我找到了简单的方法……使用“@input 函数”……这对我有用！

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},
      ]
    };
  },
  methods: {
    
    getTextSearch: function(textSearch) {

        this.filteredResources= this.resources

        this.filteredResources= this.filteredResources.filter(item => {
            return item.uri.toLowerCase().includes(textSearch);
        });

    },

  }
 

})
