Question

我正在以如下所示的html形式使用Vue Select Library中的vue-select组件，如下所示，我想在标签中显示三个值，但不知道如何实现。我在文档中找不到任何解决方案。

我要在标签中显示三个值，如下所示。

    <v-select id="selected_item" name="selected_item" title="Select an item" :options="formfieldsdata.items" :reduce="item_name => item_name.id" label="item_name+'::'+item_code+'::'+item_created_at" v-model="item.selected_item" @input="getSelectedItem"  style="width: 100%; height:56px;" />

HTML：


     <script src="{{ asset('assets/requiredjs/vue-select.js') }}"></script>
     <link href="{{ asset('assets/requiredcss/vue-select.css') }}" rel="stylesheet">


    <v-select id="selected_item" name="selected_item" title="Select an item" :options="formfieldsdata.items" :reduce="item_name => item_name.id" label="item_name" v-model="item.selected_item" @input="getSelectedItem"  style="width: 100%; height:56px;" />

JS：


    Vue.component('v-select', VueSelect.VueSelect);

    var app = new Vue({
        el: '#app',
        data: {

        formfieldsdata: {

                items: [],

            },

        item: {
                selected_item: 0,
            },

        }

        });

请参考vue选择库文档：https://vue-select.org/guide/values.html#transforming-selections

仅使用模板文字即可将表达式嵌入JavaScript字符串中。并将标签绑定到/token

:label

更新 <v-select id="selected_item" name="selected_item" title="Select an item" :options="formfieldsdata.items" :reduce="item_name => item_name.id" :label="`${item_name} ${item_code} ${item_created_at}" v-model="item.selected_item`" @input="getSelectedItem" style="width: 100%; height:56px;" />只能用于一个对象属性。但是您可以使用范围来获取选项和所选值。示例on codepen

label

更新2 多属性搜索vue-select

vue组件

<v-select id="selected_item" name="selected_item" title="Select an item" :options="formfieldsdata.items" :reduce="item_name => item_name.id"  v-model="item.selected_item" @input="getSelectedItem"  style="width: 100%; height:56px;" >


   <template slot="option" slot-scope="option">
       <span :class="option.icon"></span>
       {{ option.item_name }} {{option.item_code}} {{option.created_at}}
   </template>
   <template slot="selected-option" slot-scope="option">
       <span :class="option.icon"></span>
       {{ option.item_name }} {{option.item_code}} {{option.created_at}}
   </template>
</v-select>

 <div id="app">
  <h1>Vue Select - Multiple properties</h1>
  <v-select :options="options" label="item_data"
