Answer 2

这样呢?<textarea id='cc' style="height:80px; width:300px"></textarea>
<input name="" type="button" onclick="document.getElementById('ss').innerHTML='<pre>'+document.getElementById('cc').value+'</pre>'" />
<div id="ss"></div>

Answer 3

必然啊，在你的value中的\n之类的格式符号在innerHTML中也是\n，但是显示出来的东西要换行要加额外的<br><p>之类的标签之类的啊<div>
<!-- 这里就有换行但是显示出来不是换行 -->
<div><div>
<br/> <!-- 这样才行 -->
<div>
