本文实例讲述了jquery实现Ctrl+Enter提交表单的方法。分享给大家供大家参考。具体如下:
<!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>
希望本文所述对大家的jquery程序设计有所帮助。
