CSS+JS实现图片集展示(二)

来源:程序员人生   发布时间:2015-01-09 08:56:33 阅读次数:2945次

题目与上面的两篇文章有所重复,但是内容与上两篇上有所区分,本文中,实现的图片集展现的效果为:

1、详细图和缩略图的同步展现;

2、图片的自动播放;

3、显示图片的缩影图的焦点显示与别的图片的遮盖显示;

4、鼠标移动至详图显示图片控制控件。



具体效果图以下:


初始化或第1张状态


中间状态


最后1张状态


这类方式的图片展现1般用的图片新闻或类似的东西中比较常见,例如百度首页的新闻就是用类似的方式来展现的,以下:


百度首页新闻

下面将我实现的代码贴出来,以供大家参考。

1、showimg.css

html, body{ height: 100%; margin: 0; padding: 0; text-align: center; } #prev{ position: absolute; top: 125px; left: 0px; width: 45px; height: 50px; background: url(../img/prev.png); } #next{ position: absolute; top: 125px; right: 0px; width: 45px; height: 50px; background: url(../img/next.png); } #prev:hover,#next:hover{ cursor: pointer; } .detail-div{ position: relative; display:inline-block; padding:4px; margin:0 0.5rem 1rem 0.5rem 1rem; line-height:0; -webkit-transition:background-color 0.1s ease-out; -moz-transition:background-color 0.1s ease-out; -o-transition:background-color 0.1s ease-out; transition:background-color 0.1s ease-out; -webkit-border-radius:6px; -moz-border-radius:6px; -ms-border-radius:6px; -o-border-radius:6px; border-radius:6px; } .thumb-div{ position: absolute; bottom: ⑴10px; left: 4px; background: #555; } .thumb{ margin-left: 7px; margin-top: 5px; margin-bottom: 5px; float: left; position: relative; } .thumb-img{ -webkit-border-radius:5px; -moz-border-radius:5px; -ms-border-radius:5px; -o-border-radius:5px; border-radius:5px } .thumb-active{ border: 2px solid #fff; -webkit-border-radius:5px; -moz-border-radius:5px; -ms-border-radius:5px; -o-border-radius:5px; border-radius:5px; height: 100px; } .thumb-modal{ background: #141414; opacity: 0.5; filter:alpha(opacity=50); position: absolute; left: 0px; bottom: 2px; -webkit-border-radius:5px; -moz-border-radius:5px; -ms-border-radius:5px; -o-border-radius:5px; border-radius:5px; } .thumb-modal-hide{ display: none; }

2、juqery.showimg.js

(function($){ $.fn.showImg = function(options){ var defaults = {}; var options = $.extend(defaults, options); var container=$(this); var imgUrls = options.imgUrls; var width = options.width,height = options.height,thumbHeight = options.thumbHeight; var autoPlay = options.autoplay; container.css("width",width+"px"); var imgIndex = 1,length = imgUrls.length; var play; /** * 图片详情 */ var detailDiv = $("<div></div>").addClass("detail-div").appendTo(container); var ctrlDiv = $("<div></div>").appendTo(detailDiv).hide(); var prevA = $("<a></a>").attr("id","prev").appendTo(ctrlDiv).hide(), nextA = $("<a></a>").attr("id","next").appendTo(ctrlDiv); $(".detail-div").live("mouseenter",function(){ play = clearInterval(play); ctrlDiv.show(); }); $(".detail-div").live("mouseleave",function(){ play = setInterval(playImg,3000); ctrlDiv.hide(); }); var detailImgA = $("<a></a>").appendTo(detailDiv); var detailImg = $("<img />").attr("id","detailImg") .attr("width",width) .attr("height",height) .attr("src","img/demopage/image-"+imgIndex+".jpg") .appendTo(detailImgA); /** * 缩影图片 */ var thumbDiv = $("<div></div>").addClass("thumb-div") .appendTo(container) .css("width",width+"px"); addThumbImgs(); prevA.on("click",function(){ imgCtrlFun("prev"); }); nextA.on("click",function(){ imgCtrlFun("next"); }); if(autoPlay){ play = setInterval(playImg,3000); } function playImg(){ if(imgIndex===length){ imgIndex=0; } nextA.click(); } /** * 图片控制 * @param type */ function imgCtrlFun(type){ if(type==="prev"){ if(imgIndex>1){ imgIndex= imgIndex⑴; } } else{ if(imgIndex<length){ imgIndex= imgIndex+1; } } $("#detailImg").attr("src","img/demopage/image-"+imgIndex+".jpg"); thumbDiv.html(""); addThumbImgs(); if(imgIndex===length){ $("#next").hide(); } else{ $("#next").show(); } if(imgIndex===1){ $("#prev").hide(); } else{ $("#prev").show(); } }; /** * 添加图片缩影 */ function addThumbImgs(){ var thumbWidth = width/3⑴0; for(var i=imgIndex⑵;i<imgIndex+1;i++){ var thumb = $("<div></div>").addClass("thumb").appendTo(thumbDiv); var thumbModalDiv = $("<div></div>").addClass("thumb-modal").appendTo(thumb); thumbModalDiv.css("height",thumbHeight+"px") .css("width",thumbWidth+"px"); var thumbImg = $("<img />").attr("id","thumb"+(i+1)) .attr("width",thumbWidth) .attr("height",thumbHeight) .addClass("thumb-img") .appendTo(thumb); if(!(i<0)){ thumbImg.attr("src",imgUrls[i]); } if(i===imgIndex⑴){ thumb.addClass("thumb-active"); thumbModalDiv.addClass("thumb-modal-hide"); } } }; } })(jQuery);

3、index.html

<!DOCTYPE html> <html> <head> <meta charset="utf⑻"> <title>Image List</title> <link rel="stylesheet" href="css/showimg.css"> <style> .container{ position: relative; text-align: center; margin-left: 25%; } </style> <script src="js/jquery⑴.8.3.js"></script> <script src="js/jquery.showimg.js"></script> <script> var imgUrls = new Array( "img/demopage/image⑴.jpg", "img/demopage/image⑵.jpg", "img/demopage/image⑶.jpg", "img/demopage/image⑷.jpg", "img/demopage/image⑸.jpg" ); $(document).ready(function (){ $('#container').showImg({ imgUrls:imgUrls, width:600, height:300, thumbHeight:100, autoplay:true }); }); </script> </head> <body> <div id="container" class="container"></div> </body> </html>

思路很简单,我相信大家看完代码就知道是甚么思路,希望对大家有所帮助,抛砖引玉。
