HTML | oninput 事件属性

此属性在获取用户输入值时起作用。此属性主要在用户更改和元素的值时触发。该属性与 onchange 属性非常相似，但基本的区别是 oninput 事件属性在元素值改变时立即发生，而 onchange 属性在元素失去焦点时发生。另一个区别是 onchange 属性也适用于 <select> 元素。<br/><strong>支持的标签：</strong></p> <ul> <li> <strong><输入类型=”密码”></strong></li> <li> <strong><输入类型=“搜索”></strong></li> <li> <strong>,<输入类型=”文本”></strong></li> <li> <strong><文本区域></strong></li> </ul> <p><strong>句法：</strong> </p> <div class="hcb_wrap"> <pre class="prism line-numbers lang-html" data-lang="HTML"><code class="replace"><element oninput = "script"></code></pre> </div> <p><strong>属性值：</strong>该属性包含值<i>脚本</i>，它在 oninput 事件触发时起作用。许多 HTML 标签都支持此属性：<input type=”password”>、<input type=”search”、<input type=”text”> 和 <textarea>。<br/><strong>例子：</strong></p> <div> <h5 class="code">html</h5> <div class="hcb_wrap"> <pre class="prism line-numbers lang-html" data-lang="HTML"><code class="replace"><!DOCTYPE html> <html> <head> <title>oninput attribute</title> <style> body { text-align:center; } h1 { color:green; } </style> </head> <body> <h1>GeeksforGeeks</h1> <h2>oninput Attribute</h2> Enter some Text here: <input type="text" id="GFG" oninput="Geeks()"> <p id="sudo"></p> <script> function Geeks() { var x = document.getElementById("GFG").value; document.getElementById("sudo").innerHTML = "Entered Text: " + x; } </script> </body> </html></code></pre> </div> <p></p> <hr/> </div> <p><strong>输出：</strong> </p> <p><img alt="" class="img-fluid" src="https://mangodoc.oss-cn-beijing.aliyuncs.com/geek8geeks/HTML_%7C_oninput_Event_Attribute_0.jpg"/></p> <p></p> <div class="_ap_apex_ad" id="d6f45c53-ff16-4cc5-8b91-eb6ee7037116" style="min-height:280px"></div> <p></p> <p><strong>支持的浏览器：</strong> <i>oninput</i>事件属性支持的浏览器如下：</p> <ul> <li>苹果 Safari 5.0</li> <li>谷歌浏览器</li> <li>火狐 4.0</li> <li>歌剧</li> <li>浏览器 9.0 </li> </ul> <div class="_ap_apex_ad" id="82d2079a-8120-480f-9fc7-5cda825d56e7" style="min-height:280px"></div> <p></p></div> </article> </div> </div> </div> </div> </div> <footer> <div class="bg-white text-center pb-1"> <p class="text-body-tertiary pt-3 lh-lg text-opacity-50" id="footer-text">Copyright © 2020 - 2024 版权所有 <br> <a href="https://beian.miit.gov.cn/" target="_blank" class="text-opacity-50 text-body-tertiary mt-1 mb-1">蜀ICP备20006366号-1</a> <br> Made with ❤️ in Chengdu </p> </div> </footer>  <script src="https://unpkg.com/bootstrap@5.3.0-alpha1/dist/js/bootstrap.bundle.min.js" crossorigin="anonymous"></script>  <script src="https://cdn.jsdelivr.net/npm/@meilisearch/instant-meilisearch/dist/instant-meilisearch.umd.min.js"></script> <script src="https://cdn.jsdelivr.net/npm/instantsearch.js@4"></script> <script src="https://www.imangodoc.com/static/javascript/meili_custom.js"></script>  <script src="https://cdn.jsdelivr.net/npm/prismjs@1.29.0/components/prism-core.min.js"></script> <script src="https://cdn.jsdelivr.net/npm/prismjs@1.29.0/plugins/toolbar/prism-toolbar.min.js"></script> <script src="https://cdn.jsdelivr.net/npm/prismjs@1.29.0/plugins/autoloader/prism-autoloader.min.js"></script> <script src="https://cdn.jsdelivr.net/npm/prismjs@1.29.0/plugins/copy-to-clipboard/prism-copy-to-clipboard.min.js"></script> </body> </html>
