如何在vue组件上的下拉列表中选择值？

Question

我VUE组件，你可以看到这下面

<template> 
    <div> 
     ... 
     <select class="form-control" v-model="selected" @change="myFunction()"> 
      <option selected disabled>Status</option> 
      <option v-for="status in orderStatus" v-bind:value="status.id">{{ status.name }}</option> 
     </select> 
     ... 
    </div> 
</template> 

<script> 
    export default { 
     data() { 
      return{ 
       selected: '' 
      } 
     }, 
     methods: { 
      myFunction: function() { 
       console.log(this.selected) 
      } 
     } 
    } 
</script> 

在吞气存在错误

Vue template syntax error:

: inline selected attributes on will be ignored when using v-model. Declare initial values in the component's data option instead.

我该如何解决呢？

Answer 1

你可以将这个

<option disabled value="">Status</option> 

而是这个

<option selected disabled>Status</option> 

https://vuejs.org/v2/guide/forms.html#Select

v-model will ignore the initial value, checked or selected attributes found on any form elements. It will always treat the Vue instance data as the source of truth. You should declare the initial value on the JavaScript side, inside the data option of your component.
