【textarea标签属性】在HTML中，``标签用于创建多行文本输入框，用户可以在其中输入和编辑多行文字。与单行文本输入框不同，`<textarea>`可以容纳大量的文本内容，常用于表单中的留言、评论、描述等场景。下面是对`<textarea>`标签常用属性的总结。</p><p>一、常用属性说明</p><table><tbody><tr><td> 属性名 </td><td> 作用说明 </td></tr><tr><td> `rows` </td><td> 定义文本区域的可见行数（高度）。单位为行。</td></tr><tr><td> `cols` </td><td> 定义文本区域的可见列数（宽度）。单位为字符。</td></tr><tr><td> `value`</td><td> 设置或返回文本区域的初始值（即默认显示的内容）。</td></tr><tr><td> `disabled` </td><td> 禁用文本区域，使其不可交互。</td></tr><tr><td> `readonly` </td><td> 设置文本区域为只读，用户不能修改内容。</td></tr><tr><td> `placeholder`</td><td> 提示用户输入内容的文本，当文本区域为空时显示。</td></tr><tr><td> `wrap` </td><td> 控制文本区域中输入的文本是否自动换行。可选值有：`soft`（默认）、`hard`。 </td></tr></tbody></table><p>二、使用示例</p><p>```html</p><p><textarea rows="5" cols="30" placeholder="请输入您的留言..." disabled></p><p>这是一个被禁用的文本区域。</p><p>
```
在这个例子中，``设置了5行、30列，提示信息为“请输入您的留言...”，并且是被禁用的状态，用户无法进行输入操作。</p><p>三、注意事项</p><p>- `rows` 和 `cols` 只是定义了文本区域的大小，并不严格限制用户输入的文本长度。</p><p>- 如果需要对输入内容进行验证或限制，建议结合JavaScript实现。</p><p>- `placeholder` 属性在部分旧浏览器中可能不支持，需注意兼容性问题。</p><p>通过合理使用`<textarea>`标签及其相关属性，可以有效提升网页表单的用户体验和功能完整性。在实际开发中，根据需求选择合适的属性组合，能够更好地满足用户输入的需求。</p><style>table,tr{width: 100%;text-align: center;color: #333;font-size: 16px;line-height: 1.8em;margin-bottom: 32px;border: 1px solid #333;empty-cells:show;}table tr th {border: 1px solid #333;text-align: center;font-weight: 600;background: #eee;}table tr td {border: 1px solid #333;text-align: center}</style> </div> </div> </div> <!--内容关联投票--> <div class="clear"></div> <div id="SGOContentPage" class="SiteGeneralContentPage" style="margin-top:15px;"></div> <div class="article_footer clearfix"> <div class="fr tag"> 标签： <a href="https://www.howvc.com/tag/textareabiaoqianshuxing/" target="_blank">textarea标签属性</a> </div> </div> <div class="content_banquan"> <p><span class="strong">免责声明：本答案或内容为用户上传，不代表本网观点。其原创性以及文中陈述文字和内容未经本站证实，对本文以及其中全部或者部分内容、文字的真实性、完整性、及时性本站不作任何保证或承诺，请读者仅作参考，并请自行核实相关内容。 如遇侵权请及时联系本站删除。</span></p> </div> <script> if (isMobile()){ document.write('<div style="text-align:center;margin-top:10px;margin-left:-15px;"><script>wap_show_tag_under9();<\/script><\/div>');
