js获取修改title与jQuery获取修改title_jq title
发布时间：2025-04-08 16:03:57来源：
🌐 在现代网页开发中，动态修改网页标题（`
`标签）是一个常见的需求，无论是为了优化SEO还是提升用户体验。通过JavaScript原生方法或jQuery插件，我们都能轻松实现这一功能。本文将分别介绍如何使用JavaScript和jQuery来获取并修改网页标题，并结合实际场景分享一些小技巧。</p><p>首先，使用JavaScript直接操作网页标题非常简单。只需调用`document.title`即可完成读取或设置操作。例如：</p><p>```javascript</p><p>// 获取当前标题</p><p>const originalTitle = document.title;</p><p>console.log(originalTitle);</p><p>// 修改标题</p><p>document.title = "新标题 🌟";</p><p>```</p><p>接着，借助jQuery框架也能实现类似效果。虽然jQuery本身没有专门针对`<title>`标签的方法，但可以通过选择器访问文档对象来达到目的：</p><p>```javascript</p><p>// 使用jQuery获取标题</p><p>let jqTitle = $(document).prop('title');</p><p>console.log(jqTitle);</p><p>// 使用jQuery修改标题</p><p>$(document).prop('title', '新标题 💫');</p><p>```</p><p>两种方式各有优势，原生JavaScript运行效率更高，而jQuery则提供了更简洁的语法支持。无论选择哪种方案，在实际开发中都应确保修改后的标题语义明确且吸引人，比如添加品牌标志或关键信息。</p><p>💡 小贴士：当页面需要频繁更新标题时，建议先保留原始标题作为备用值，避免因多次修改导致用户体验下降。此外，合理运用表情符号可以让标题更加生动有趣，但需注意不要过度堆砌以免适得其反！</p> <!--内容关联投票-->
