如何在 Vue.js 中动态添加很棒的字体图标

Question

我有两个输入位于模态中，还有一个按钮，当用户单击它时会生成另外两个输入。它可以工作，但我想在两个输入旁边添加一个很棒的字体图标，仅用于动态创建的输入，如何在 Vue 中实现此目的？到目前为止，这是我的代码：<div class="price-round-creation-containe" v-for="(shareholder, index) in shareholders" :key="index">  <div>    <input v-model="shareholder.username" :name="`shareholders[${index}][username]`" type="text" class="form-control input" >  </div>  <div>    <input v-model="shareholder.investment" :name="`shareholders[${index}][investment]`" type="text" class="form-control input" >  </div></div><p  class="add-new-shareholders-p"  @click="createNewPricedRoundShareholder">  <i class="fa fa-plus-circle fa-lg" />ADD NEW SHAREHOLDER</p>我的数据：shareholders: [  {    investment: "Investment",    username: "Username"  },]以及我的添加按钮的功能：createNewPricedRoundShareholder() { this.shareholders.push({    username: "Username",    investment: "Investment"  },}

Answer 1

dynamic: true您可以在添加项中添加额外的属性：

this.shareholders.push({

  username: "Username",

  investment: "Investment",

  dynamic: true

})

并在显示输入时检查它：

<div>

   <input v-model="shareholder.username" :name="`shareholders[${index}][username]`" type="text" class="form-control input" >

   <i v-if="shareholder.dynamic" class="fa fa-plus-circle fa-lg" />

</div>

<div>

   <input v-model="shareholder.investment" :name="`shareholders[${index}][investment]`" type="text" class="form-control input" >

   <i v-if="shareholder.dynamic" class="fa fa-plus-circle fa-lg" />

</div>
