当我们需要捕获用户的键盘输入时，onkeypress 事件属性是一个常用的工具。只要用户按下键盘上的某个键，该属性就会被触发。不过，我们需要特别注意，在所有浏览器中，这个事件并不能识别所有的按键（例如 ALT、CTRL、SHIFT、ESC 等功能键通常不会触发它）。
支持的标签：
除了以下几个标签外，所有的 HTML 元素都支持 onkeypress 属性：
</li> </ul> <p><strong><em><em>语法：</em></strong></em></p> <pre><code> </code></pre> <p><strong><em><em>属性详解：</em></strong></em></p> <p>如果我们需要捕获所有按键（包括前面提到的那些功能键），INLINECODE<em>5841b74a 属性通常是更好的选择，因为它在所有浏览器中对所有按键都有效。当 INLINECODE</em>de140775 事件被触发时，我们指定的脚本就会运行。</p> <p><strong><em><em>注意：</em></strong></em></p> <p>需要注意的是，<strong>这个属性已经被弃用（Deprecated）</strong>，我们不再推荐在新的开发项目中使用它。为了让大家更清楚地理解事件发生的顺序，以下是相关的键盘事件触发顺序：</p> <ul> <li>onkeydown（按键按下）</li> <li>onkeypress（按键字符输入）</li> <li>onkeyup（按键松开）</li> </ul> <p><strong><em><em>示例：</em></strong></em></p> <p>让我们通过一个简单的代码示例来看看它是如何工作的。</p> <p>HTML</p> <p><code><br /> CODEBLOCK_cfaea07e<br /> </code><br /> <strong><em><em>输出效果：</em></strong></em></p> <p>!<a
