这篇文章主要介绍了jQuery实现图片局部放大镜效果的相关资料,需要的朋友可以参考下

下图只是给大家举个例子，类似于这种效果图：

具体实现过程请看下文代码：

css:

.zoomPad{

position:relative;

float:left;

z-index:99;

cursor:crosshair;

}

.zoomPreload{

-moz-opacity:0.8;

opacity: 0.8;

filter: alpha(opacity = 80);

color: #333;

font-size: 12px;

font-family: Tahoma;

text-decoration: none;

border: 1px solid #CCC;

padding: 8px;

text-align:center;

background-image: url(/images/zoomloader.gif);

background-repeat: no-repeat;

background-position: 43px 30px;

z-index:110;

width:90px;

height:43px;

position:absolute;

top:0px;

left:0px;

* width:100px;

* height:49px;

}

.zoomPup{

overflow:hidden;

-moz-opacity:0.6;

opacity: 0.6;

filter: alpha(opacity = 60);

z-index:120;

position:absolute;

border:1px solid #CCC;

z-index:101;

cursor:crosshair;

}

.zoomOverlay{

position:absolute;

left:0px;

top:0px;

/*opacity:0.5;*/

z-index:5000;

width:100%;

height:100%;

display:none;

z-index:101;

}

.zoomWindow{

position:absolute;

left:110%;

top:40px;

z-index:6000;

height:auto;

z-index:10000;

z-index:110;

}

.zoomWrapper{

position:relative;

border:1px solid #999;

z-index:110;

}

.zoomWrapperTitle{

display:block;

background:#999;

color:#FFF;

height:18px;

line-height:18px;

width:100%;

overflow:hidden;

text-align:center;

font-size:10px;

position:absolute;

top:0px;

left:0px;

z-index:120;

-moz-opacity:0.6;

opacity: 0.6;

filter: alpha(opacity = 60);

}

.zoomWrapperImage{

display:block;

},

disable: function (el) {

var api = $(el).data('jqzoom');

api.disable();

return false;

},

enable: function (el) {

var api = $(el).data('jqzoom');

api.enable();

return false;

},

disableAll: function (el) {

jqzoompluging_disabled = true;

},

enableAll: function (el) {

jqzoompluging_disabled = false;

}

};

})(jQuery);

还需要有Jquery.js

使用方法：

1.当页面导入的时候，载入 jQZoom 插件。

$(function(){

$(".jqzoom").jqzoom({

zoomWidth: 300, 

zoomHeight: 300,

lens:true,

preloadImages: false,

alwaysOn:false,

title:false,

xOffset:20,

position: "right"

});

})

2.创建一个放图片的容器，指定一个a标记用于显示放大后的图片的一部分：

<a href="images/BIGIMAGE.JPG" class="jqzoom" title="MYTITLE"> 

<img src="images/SMALLIMAGE.JPG" title="IMAGE TITLE"> 

</a>

下面给一些基本的配置参数：

•zoomType，默认值：'standard'，另一个值是'reverse'，是否将原图用半透明图层遮盖。

•zoomWidth，默认值：200，放大窗口的宽度。

•zoomHeight，默认值：200，放大窗口的高度。

•xOffset，默认值：10，放大窗口相对于原图的x轴偏移值，可以为负。

•yOffset，默认值：0，放大窗口相对于原图的y轴偏移值，可以为负。

•position，默认值：'right'，放大窗口的位置，值还可以是:'right' ,'left' ,'top' ,'bottom'。

•lens，默认值：true，若为false，则不在原图上显示镜头。

•imageOpacity，默认值：0.2，当zoomType的值为'reverse'时，这个参数用于指定遮罩的透明度。

•title，默认值：true，在放大窗口中显示标题，值可以为a标记的title值，若无，则为原图的title值。

•showEffect，默认值：'show'，显示放大窗口时的效果，值可以为: ‘show' ,'fadein'。

•hideEffect，默认值：'hide'，隐藏放大窗口时的效果: ‘hide' ,'fadeout'。

•fadeinSpeed，默认值：'fast'，放大窗口的渐显速度(选项: ‘fast','slow','medium')。

•fadeoutSpeed，默认值：'slow'，放大窗口的渐隐速度(选项: ‘fast','slow','medium')。

•showPreload，默认值：true，是否显示加载提示Loading zoom(选项: ‘true','false')。

•preloadText，默认值：'Loading zoom'，自定义加载提示文本。

•preloadPosition，默认值：'center'，加载提示的位置，值也可以为'bycss'，以通过css指定位置。

样式的个性化当然也可以直接修改jqzoom.css文件。
