🌟textarea 默认文字，点击消失💬✨

发布时间：2025-03-23 14:08:55来源：

在日常网页设计中，``组件中的`textarea`功能常常被用来收集用户反馈或长文本输入。一个贴心的设计是为其添加默认提示文字，比如“请输入您的想法~”🧐，这样既能引导用户操作，又能让界面更友好。但问题来了，当用户点击时，默认文字会自动消失，这背后是如何实现的呢？🤔

其实，这种效果可以通过简单的HTML和CSS轻松搞定！首先，在``标签内使用`placeholder`属性设置默认文字；然后，利用JavaScript监听焦点事件，一旦用户开始输入，就让默认文字消失。这样的交互方式不仅提升了用户体验，还避免了干扰用户的正常输入。💡</p><p>如果你也想打造类似的功能，不妨试试这种方法吧！😉 无论是写日记、发表评论还是填写问卷，都能让用户感受到满满的诚意与便利！📝✨</p>  <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： </div> </div> <script> if (isMobile()){ document.write('<div style="text-align:center;margin-top:10px;margin-left:-12px;"><script>wap_show_sosuo();<\/script><\/div>');
