这次我们要分享的这款jQuery焦点图非常特别,它的外观特别简单,但是又相当大气。焦点图的整体样式是仿苹果样式的,由于jQuery的运用,我们只要点击图片下方的缩略图即可达到图片切换的焦点图特效,这款jQuery焦点图插件非常适合在产片展示的网页上使用。

接下来我们一起分享一下实现这款苹果焦点图的过程及源码。
HTML代码:
<div id="gallery"> <div id="slides" style="width: 3680px; margin-left: 0px;"> <div class="slide"><img width="920" height="400" alt="side" src="img/sample_slides/macbook.jpg"></div> <div class="slide"><img width="920" height="400" alt="side" src="img/sample_slides/iphone.jpg"></div> <div class="slide"><img width="920" height="400" alt="side" src="img/sample_slides/imac.jpg"></div> <div class="slide"><a target="_blank" href="http://tutorialzine.com/2009/10/beautiful-apple-gallery-slideshow/"><img width="920" height="400" alt="side" src="img/sample_slides/info.jpg"></a></div> </div> <div id="menu"> <ul> <li class="fbar inact"> </li><li class="menuItem inact act"><a href=""><img alt="thumbnail" src="img/sample_slides/thumb_macbook.png"></a></li><li class="menuItem inact"><a href=""><img alt="thumbnail" src="img/sample_slides/thumb_iphone.png"></a></li><li class="menuItem inact"><a href=""><img alt="thumbnail" src="img/sample_slides/thumb_imac.png"></a></li><li class="menuItem inact"><a href=""><img alt="thumbnail" src="img/sample_slides/thumb_about.png"></a></li> </ul> </div> </div>
从以上HTML代码可以看出,整个焦点图由一些div构成图片容器,用ul li列表构成下面的缩略图。
CSS代码:
#gallery{ /* CSS3 Box Shadow */ -moz-box-shadow:0 0 3px #AAAAAA; -webkit-box-shadow:0 0 3px #AAAAAA; box-shadow:0 0 3px #AAAAAA; /* CSS3 Rounded Corners */ -moz-border-radius-bottomleft:4px; -webkit-border-bottom-left-radius:4px; border-bottom-left-radius:4px; -moz-border-radius-bottomright:4px; -webkit-border-bottom-right-radius:4px; border-bottom-right-radius:4px; border:1px solid white; background:url(img/panel.jpg) repeat-x bottom center #ffffff; /* The width of the gallery */ width:920px; overflow:hidden;}#slides{ /* This is the slide area */ height:400px; /* jQuery changes the width later on to the sum of the widths of all the slides. */ width:920px; overflow:hidden;}.slide{ float:left;}#menu{ /* This is the container for the thumbnails */ height:45px;}ul{ margin:0px; padding:0px;}li{ /* Every thumbnail is a li element */ width:60px; display:inline-block; list-style:none; height:45px; overflow:hidden;}li.inact:hover{ /* The inactive state, highlighted on mouse over */ background:url(img/pic_bg.png) repeat;}li.act,li.act:hover{ /* The active state of the thumb */ background:url(img/active_bg.png) no-repeat;}li.act a{ cursor:default;}.fbar{ /* The left-most vertical bar, next to the first thumbnail */ width:2px; background:url(img/divider.png) no-repeat right;}li a{ display:block; background:url(img/divider.png) no-repeat right; height:35px; padding-top:10px;}a img{ border:none;}
CSS代码也非常简单,都是一些简单设置而已。
jQuery代码:
$(document).ready(function(){ /* This code is executed after the DOM has been completely loaded */ var totWidth=0; var positions = new Array(); $(‘#slides .slide‘).each(function(i){ /* Traverse through all the slides and store their accumulative widths in totWidth */ positions[i]= totWidth; totWidth += $(this).width(); /* The positions array contains each slide‘s commulutative offset from the left part of the container */ if(!$(this).width()) { alert("Please, fill in width & height for all your images!"); return false; } }); $(‘#slides‘).width(totWidth); /* Change the cotnainer div‘s width to the exact width of all the slides combined */ $(‘#menu ul li a‘).click(function(e,keepScroll){ /* On a thumbnail click */ $(‘li.menuItem‘).removeClass(‘act‘).addClass(‘inact‘); $(this).parent().addClass(‘act‘); var pos = $(this).parent().prevAll(‘.menuItem‘).length; $(‘#slides‘).stop().animate({marginLeft:-positions[pos]+‘px‘},450); /* Start the sliding animation */ e.preventDefault(); /* Prevent the default action of the link */ // Stopping the auto-advance if an icon has been clicked: if(!keepScroll) clearInterval(itvl); }); $(‘#menu ul li.menuItem:first‘).addClass(‘act‘).siblings().addClass(‘inact‘); /* On page load, mark the first thumbnail as active */ /***** * * Enabling auto-advance. * ****/ var current=1; function autoAdvance() { if(current==-1) return false; $(‘#menu ul li a‘).eq(current%$(‘#menu ul li a‘).length).trigger(‘click‘,[true]); // [true] will be passed as the keepScroll parameter of the click function on line 28 current++; } // The number of seconds that the slider will auto-advance in: var changeEvery = 10; var itvl = setInterval(function(){autoAdvance()},changeEvery*1000); /* End of customizations */});
这是焦点图的重点,完成了图片滑块的动画逻辑,点击缩略图即可切换图片。
