Vue.js 和多选 - 名称"input"在当前上下文中不存在

Question

我试图在使用@input更改组件 Vue Multiselect 的值后启动一个方法，但我收到以下编译错误：

CS0103：当前上下文中不存在名称"输入"

这是我的多选：

<multiselect v-model="Instalacao.value" label="Serie" track-by="Serie" placeholder="Nº de série" :options="Instalacoes"
    :multiple="false" :searchable="true" :allow-empty="false" :disabled="Editando" @input="getTecnicosByRepresentante">
    <span slot="noResult">Nenhum técnico encontrado</span>
</multiselect>

Answer 1

此示例按预期工作：选择值时，watch 和@input处理程序都将执行。您的问题可能不在此处包含的代码中。

new Vue({
  el: '#app',
  components: {
    Multiselect: window.VueMultiselect.default
  },
  data: {
    Instalacao: {
      value: null
    },
    Instalacoes: [{
        Serie: 'one',
        value: 'Vue.js'
      },
      {
        Serie: 'two',
        value: 'Vue-Multiselect'
      },
      {
        Serie: 'three',
        value: 'Vuelidate'
      }
    ]
  },
  watch: {
    'Instalacao.value': function(newValue) {
      console.log('Updated', newValue);
    }
  },
  methods: {
    getTecnicosByRepresentante() {
      console.log("Input detected, too");
    }
  }
})
