<div class="editor">
  <vue-at-textarea
    v-model="content"
    @change="handleChange"
    :members="members"
  />
</div>
<style>
.editor {
  width: 500px;
  height: 200px;
  border: 1px solid #eee;
  position: relative;
}
</style>

<template>
  <button @click="handleInsert">插入内容</button>
  <div class="chat-footer">
    <vue-at-textarea
      ref="textarea"
      v-model="content"
      @change="handleChange"
      :members="members"
    />
  </div>
</template>
<script>
  export default {
    methods: {
      handleInsert() {
        // 如果需要插入@用户字符串 在用户名字后面 必须留有空格 @黄坤 
        // 插入该用户后 会自动返回 相匹配的对应用户 触发 change 事件
        this.$refs.textarea.insertValue('@黄坤 ')
      }
    }
  }
</script>
