彈出層效果很多網站上都用到，今天就整理最近項目裡用到的一個小效果，點擊折疊彈出一個層給用戶填寫信息。彈出層代碼都是jq動態創建，每個人寫法都不一樣，需求也不一樣，所有選擇符合自已的即可。 html： 代碼如下: <h1 class="bm"><a href="javascript:;">我要報名</a></h1> 代碼如下: *{ margin:0; padding:0;} body{ font:14px 'Microsoft YaHei'; color:#555;} li{ list-style:none;} .layer_bg{ position:fixed; top:0; left:0; width:100%; height:100%; background:#000; z-index:10; display:none;} .layer_item{ position:fixed; left:50%; top:50%; width:600px; margin-left:-300px; display:inline; overflow:hidden; background:#fff; z-index:11;} .layer_item .layer_title{ float:left; width:100%; height:75px; line-height:75px; overflow:hidden; background:#FF4E00;} .layer_item .layer_title h1{ float:left; font-weight:normal; font-size:35px; text-indent:20px; color:#fff;} .layer_item .layer_title a{ float:right; width:75px; height:75px; line-height:65px; text-align:center; font-size:60px; color:#fff; text-decoration:none; background:#535961;} .layer_item ul{ float:left; width:100%; padding:10px 0;} .layer_item ul li{ float:left; width:100%; line-height:35px; padding:10px 0; overflow:hidden;} .layer_item ul li span{ float:left; width:100px; text-indent:20px; text-align:right; padding-right:10px;} .layer_item ul li span b{ color:Red;} .layer_item ul li .layer_txt{ float:left; width:300px; height:23px; line-height:23px; padding:5px; border:1px solid #dfdfdf;} .layer_item ul li #message{ width:400px; height:150px;} .layer_item .layer_btn{ float:left; width:100%; padding-bottom:40px;} .layer_item .layer_btn .layer_submit_btn{ float:left; width:100px; height:40px; text-align:center; overflow:hidden; background:#FF4E00; color:#fff; margin-left:110px; display:inline; border:none; font:14px 'Microsoft YaHei'; line-height:40px; } jq: 代碼如下: $(function () { var layer_bg = '<div class="layer_bg"></div>'; //layer_bg var layer = '<div class="layer_item">'; //layer_item layer += '<div class="layer_title"><h1>我要報名</h1><a href="javascript:;" title="關閉">x</a></div>'; //layer_title layer += '<ul>'; //layer_cont layer += '<li><span>真實姓名<b>*</b>：</span><input type="text" class="layer_txt" name="name"></li>'; layer += '<li><span>手機<b>*</b>：</span><input type="text" class="layer_txt" name="tel"></li>'; layer += '<li><span>QQ：</span><input type="text" class="layer_txt" name="qq"></li>'; layer += '<li><span>報名人數<b>*</b>：</span><input type="text" class="layer_txt" name="num"></li>'; layer += '<li><span>留言：</span><textarea id="message" rows="2" cols="20" class="layer_txt"></textarea></li>'; layer += '</ul>'; //layer_cont end layer += '<div class="layer_btn"><input type="submit" class="layer_submit_btn" value="提交" /></div>'; layer += '</div>'; //layer_item end $('body').append(layer_bg); $('body').append(layer); var winW = $(window).width(); var winH = $(window).height(); var objH = $('.layer_item').height(); var objW = $('.layer_item').width(); $('.layer_item').css({ 'height': 0 }); $('.bm').click(function () { $('.layer_bg').css('opacity',0.7).fadeIn(); $('.layer_item').animate({ 'height': objH, 'marginTop': -objH / 2 },500); }); $('.layer_title a').on('click', function () { $('.layer_item').animate({ 'height': 0, 'marginTop': 0 }, 200, function () { $('.layer_bg').fadeOut(); }); }); });
