现在整理下发出来,希望大家共同学习吧 先看效果图: 用了jquery.image-maps.js这个插件 下载地址 http://www.jb51.net/jiaoben/57930.html原理是: 通过拖动计算出当前热区可移动模块的left top right bottom 对应area的 coords 属性集成上面的位置,就可以实现热区了。 对应的模块代码是: 复制代码 代码如下: js代码: 复制代码 代码如下: (function($) { jQuery.fn.imageMaps = function(setting) { var $container = this; if ($container.length == 0) return false; $container.each(function(){ var container = $(this); var $images = container.find('img[ref=imageMaps]'); $images.wrap('').css('border','1px solid #ccc'); $images.each(function(){ var _img_conrainer = $(this).parent(); _img_conrainer.append('添加热点上传图片删除×').append('模块-1').append($.browser.msie ? $('').css({ background:'#fff', opacity:0 }) : ''); var _img_offset = $(this).offset(); var _img_conrainer_offset = _img_conrainer.offset(); _img_conrainer.find('.position-conrainer').css({ top: _img_offset.top - _img_conrainer_offset.top, left: _img_offset.left - _img_conrainer_offset.left, width:$(this).width(), height:$(this).height(), border:'1px solid transparent' }); var map_name = $(this).attr('usemap').replace('#',''); if(map_name !=''){ var index = 1; var _link_conrainer = _img_conrainer.find('.link-conrainer ul'); var _position_conrainer = _img_conrainer.find('.position-conrainer'); var image_param = $(this).attr('name') == '' ?
