本文實例講述了jquery實現Ctrl+Enter提交表單的方法。分享給大家供大家參考。具體如下：
<!DOCTYPE HTML> <html> <head> <meta http-equiv="content-type" content="text/html; charset=utf-8"> <title>Text Box Enter</title> <style type="text/css" media="screen"> body { font: 16px/1.5 helvetica-neue, helvetica, arial, san-serif; } textarea { border: 1px solid #ccc; display: block; width: 250px; height: 100px; } p { border: 1px solid #ccc; background: #ececec; padding: 10px; margin: 10px 0; width: 230px; } button { border: 1px solid #ccc; background: #ececec; -webkit-border-radius: 3px; -moz-border-radius: 3px; margin-top: 10px; padding: 5px 20px; } </style> </head> <body> <textarea name="msg" id="msg" placeholder="Your Message" autofocus="true"></textarea> <button type="submit">Post</button> <script type="text/javascript" charset="utf-8" src="https://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js"></script> <script type="text/javascript" charset="utf-8"> $.fn.ctrlEnter = function (btns, fn) { var thiz = $(this); btns = $(btns); function performAction (e) { fn.call(thiz, e); }; thiz.bind("keydown", function (e) { if (e.keyCode === 13 && e.ctrlKey) { performAction(e); e.preventDefault(); } }); btns.bind("click", performAction); } $("#msg").ctrlEnter("button", function () { $("<p class='post'></p>").append(this.val().replace(//n/g, "<br/>")).fadeIn('slow').prependTo(document.body); this.val(""); }); </script> </body> </html>希望本文所述對大家的jquery程序設計有所幫助。
