Question

有人可以帮忙。这是我的脚本，它收集表情符号列表并将alt关键字呈现为在表情文本区域栏上绘制的相应笑脸，然后在用户点击进入时在预览div上呈现显示。但是在单击笑脸图片时会弹出图片/图像的迭代列表，当您选择其中任何一个时，它会在文本字段上呈现绘图，但是在第二次无法渲染时单击它，只是给出了文本。图像的替代文字。此外，当您点击发送时，绘制的样式将拒绝显示在div预览中。

<div class="chat">
    <div class="preview"></div><br>
      <textarea name="comment" rows="2" tabindex="4" id="comment" placeholder="Type here..."></textarea>
  </div>

下面列出了我到目前为止所做的工作。
