将默认值设置为选项选择菜单

I want to bind a custom attribute to an option select menu. The <option> tag would simply have an attribute of selected="selected"

<template>
  <div>
    <select>
      <option v-for="" v-bind:selected="[condition ? selected : notSelected]" value="">{{ resource.xprm_name }}</option>
    </select>
  </div>
</template>

data: {
  selected: "selected",
  notSelected: ""
}

This does not work, but if I change v-bind:selected to v-bind:class then it receives the appropriate class, so the logic is working, but not with the selected attribute.

有什么办法可以使其与此类自定义属性一起使用？

最佳答案

You can just use v-model for selecting a default value on a select box:

标记：

<div id="app">
  <select v-model="selected">
     <option value="foo">foo</option>
     <option value="bar">Bar</option>
     <option value="baz">Baz</option>
  </select>
</div>

查看模型：

new Vue({
  el: "#app",
  data: {
    selected: 'bar'
  }
});
