这是HTML代码

<body> <div id="box"> <img class="bgImg"src=""> <figure class="lightbox-item"> <img src="./img/1.jpg" alt=""> <figcaption>二狗子</figcaption> </figure> <img class="bgImg"src=""> <figure class="lightbox-item"> <img src="./img/2.jpg" alt=""> <figcaption>茂茂</figcaption> </figure> <img class="bgImg"src=""> <figure class="lightbox-item"> <img src="./img/3.jpg" alt=""> <figcaption></figcaption> </figure> <img class="bgImg"src=""> <figure class="lightbox-item"> <img src="./img/4.jpg" alt=""> <figcaption>天空</figcaption> </figure> <img class="bgImg"src=""> <figure class="lightbox-item"> <img src="./img/6.jpg" alt=""> <figcaption>王富贵</figcaption> </figure> <img class="bgImg"src=""> <figure class="lightbox-item"> <img src="./img/5.jpg" alt=""> <figcaption>夕阳</figcaption> </figure> </div> </body>

这是css代码

body{ margin: 0; text-align: center; } #box{ width: 100%; height: 800px; margin: 50px; } img{ width: 500px; height: 350px; } .lightbox-item{ width: 500px; height: 350px; float: left; cursor: pointer; text-align: center; overflow: hidden; position: relative; } figcaption{ position: absolute; color: yellow; font-size: 32px; left: 45%; top: 45%; } figcaption:hover{ border:2px solid white; } .fillbg { background-color: rgba(0, 0, 0, 0.6); bottom: 0; height: 100%; left: 0; opacity: 0; position: fixed; right: 0; top: 0; width: 100%; z-index: 1100; display:none; } .fillbg-active { opacity: 1; display:block; } .bgImg{ max-width: 100%; max-height: 100%; position: fixed; display: none; }

这是jq代码

$(function(){ // var newImg; var clientH=$(window).height(); var clientW=$(window).width(); var w = '800';//遮罩图片的宽 var h = '500';//遮罩图片的高 $(document).ready(function(){ $(".lightbox-item").bind("click", function(){ //绑定事件 $('.bgImg').css('display','block'); //点击后隐藏遮罩 newImg = $(this).find('img').attr('src'); //获取当前的图片 // console.log(newImg); $("body").append('<div class="fillbg"></div>'); //插入遮罩 $(".fillbg").addClass("fillbg-active"); //添加类名 $('.bgImg').css({'width': w+"px",'height': h+"px",'top':(clientH-h)/2+"px",'left':(clientW-w)/2+"px",'z-index':1101}); $('.bgImg').attr("src",newImg); }); $(".bgImg").bind("click", function(){ $(".fill-input").removeClass("fill-input-active"); setTimeout(function(){ $(".fillbg-active").removeClass("fillbg-active"); $(".fillbg").remove(); },300); $('.bgImg').css({'width': '0px','height': '0px'}); $('.bgImg').attr("src",''); }); }); });
