HTML代码如下：
<!doctype html> <html lang="zh"> <head> <meta charset="UTF-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1"> <meta content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no" /> <title>jQuery+CSS3创意搜索框特效 - 何问起</title> <link type="text/css" href="https://hovertree.com/texiao/jquery/26/css/default.css" /> <!--必要样式--> <link type="text/css" href="https://hovertree.com/texiao/jquery/26/css/search-form.css" /> </head> <body> <div> <a href="https://hovertree.com/">首页</a> <a href="https://hovertree.com/texiao/">特效</a> <a href="https://hovertree.com/h/bjaf/sousuokuang.htm">原文</a> </div> <form onSubmit="submitFn(this, event);"> <div> <div> <input type="text" placeholder="请输入关键词" /> <input type="hidden" /> <button><span></span></button> </div> <span></span> <div> </div> </div> </form> <script src="https://hovertree.com/ziyuan/jquery/jquery-1.12.0.min.js" type="text/javascript"></script> <script type="text/javascript" src="https://hovertree.com/texiao/jquery/26/js/hovertreesearch.js"></script> </body> </html>
其中hovertreesearch.js的代码如下：
function searchToggle(obj, evt) { var container = $(obj).closest('.search-wrapper'); if (!container.hasClass('active')) { container.addClass('active'); evt.preventDefault(); } else if (container.hasClass('active') && $(obj).closest('.input-holder').length == 0) { container.removeClass('active'); // clear input container.find('.search-input').val(''); // clear and hide result container when we press close container.find('.result-container').fadeOut(100, function () { $(this).empty(); }); } } function submitFn(obj, evt) { var value = $(obj).find('.search-input').val().trim(); var _html = "您搜索的关键词： "; if (!value.length) { _html = "关键词不能为空。"; } else { window.open("http://cn.bi" + "ng.com/search?q=site%3Ahove" + "rtree.com " + value + "&hewenqi=yestop"); _html += "<b>" + value + "</b>"; } $(obj).find('.result-container').html('<span>' + _html + '</span>'); $(obj).find('.result-container').fadeIn(100); evt.preventDefault(); }
