使用 alpine JS 添加和删除 dom 元素

找到了解决方案，这就是我所做的。

HTML

<div x-data="addRemove()">
  <template x-for="(field, index) in fields" :key="field.id">
    <div>
      <input type="text" name="txt1[]" class="form-input">
      <button type="button" class="btn btn-danger btn-small" @click="removeField(field)">&times;</button>
    </div>
  </template>
  <button type="button" @click="addNewField()">+ Add Row</button>
</div>

JAVASCRIPT

function addRemove() {
    return {
        fields: [],
        addNewField() {
            this.fields.push({id: new Date().getTime() + this.fields.length});
        },
        removeField(field) {
            this.fields.splice(this.fields.indexOf(field), 1);
        }
    }
}
