JavaScript code for case-sensitive locking

Tip: you can modify some code before running

<form action="#" method="post"><p><label for="password">Password:</label><input type="password" id="password" name="password" />The upper-case lock key is pressed. Note the case sensitivity.</p></form><script type="text/javascript">//<![CDATA[function detectCapsLock(event){var e = event||window.event;var o = e.target||e.srcElement;var oTip = o.nextSibling; var keyCode = e.keyCode||e.which; // 按键的keyCode var isShift = e.shiftKey ||(keyCode == 16 ) || false ; // shift键是否按住 if ( ((keyCode >= 65 & keyCode <= 90 )&&! IsShift) // Caps Lock is enabled without holding down the shift key | (keyCode> = 97 & keyCode <= 122) & isShift) // Caps Lock is enabled, and press the shift key) {oTip. style. display = '';} else {oTip. style. display = 'none';} document. getElementById ('password '). onkeypress = detectCapsLock; //]></script> </td> </tr></table>
