vue3 中 Element el-input textarea 回车发送不换行，ctrl+enter 实现换行

 <el-input
           v-if="activeInputType === 'text'"
           autosize
           type="textarea"
           v-model="searchValue"
           @keydown.native="handleKeyCode($event)"
           placeholder="请输入您想问的内容"
         >

function handleKeyCode(event: any) {
  if (event.keyCode == 13) {
    if (!event.ctrlKey) {
      event.preventDefault();
      handleSend();
    } else {
      searchValue.value += '\n';
    }
  }
}
