textarea换行问题怎么解决

2025-7-22

要解决textarea换行问题，可以使用以下方法之一：

使用CSS样式：可以通过设置white-space属性为pre-wrap或pre-line来实现textarea的换行效果。例如：

使用JavaScript：可以通过在输入框中按下Enter键时添加换行符\n来实现换行效果。例如：

这样在输入框中按下Enter键时，会在当前光标位置插入一个换行符\n。

使用PHP：如果是通过PHP生成的标签，可以在生成文本时使用<code>\n</code>来表示换行。例如：</p> <pre class="corepress-code-pre"><code><code class="php">$text = "第一行\n第二行"; echo "<textarea>".$text."";

这样生成的标签中的文本会显示为两行，即第一行和第二行。<br />无论使用哪种方法，都可以实现textarea的换行效果。</p></p> <div class="load-all-content-warp"><div class="load-all-content-btn">阅读剩余</div></div> </div> <div class="single-copyright"> <div>
