IE6不支持图片onmousemove 怎么办
又是万恶的IE6...
1、新建一个文件csshover.htc内容如下
<attach event="ondocumentready" handler="parseStylesheets" /> <script language="JScript"> /** * Pseudos - V1.30.050121 - hover & active * --------------------------------------------- * Peterned -http://www.pc175.com/ * (c) 2005 - Peter Nederlof * * Credits - Arnoud Berendsen * - Martin Reurings * - Robert Hanson * * howto: body { behavior:url("csshover.htc"); } * --------------------------------------------- */ var currentSheet, doc = window.document, activators = { onhover:{on:'onmouseover', off:'onmouseout'}, onactive:{on:'onmousedown', off:'onmouseup'} } function parseStylesheets() { //window.alert("hi"); var sheets = doc.styleSheets, l = sheets.length; for(var i=0; i<l; i++) parseStylesheet(sheets[i]); } function parseStylesheet(sheet) { if(sheet.imports) { try { var imports = sheet.imports, l = imports.length; for(var i=0; i<l; i++) parseStylesheet(sheet.imports[i]); } catch(securityException){} } try { var rules = (currentSheet = sheet).rules, l = rules.length; for(var j=0; j<l; j++) parseCSSRule(rules[j]); } catch(securityException){} } function parseCSSRule(rule) { var select = rule.selectorText, style = rule.style.cssText; if(!(/(^|\s)(([^a]([^ ]+)?)|(a([^#.][^ ]+)+)):(hover|active)/i).test(select) || !style) return; var pseudo = select.replace(/[^:]+:([a-z-]+).*/i, 'on$1'); var newSelect = select.replace(/(\.([a-z0-9_-]+):[a-z]+)|(:[a-z]+)/gi, '.$2' + pseudo); var className = (/\.([a-z0-9_-]*on(hover|active))/i).exec(newSelect)[1]; var affected = select.replace(/:hover.*$/, ''); var elements = getElementsBySelect(affected); currentSheet.addRule(newSelect, style); for(var i=0; i<elements.length; i++) new HoverElement(elements[i], className, activators[pseudo]); } function HoverElement(node, className, events) { if(!node.hovers) node.hovers = {}; if(node.hovers[className]) return; node.hovers[className] = true; node.attachEvent(events.on, function() { node.className += ' ' + className; }); node.attachEvent(events.off, function() { node.className = node.className.replace(new RegExp('\\s+'+className, 'g'),''); }); } function getElementsBySelect(rule) { var parts, nodes = [doc]; parts = rule.split(' '); for(var i=0; i<parts.length; i++) { nodes = getSelectedNodes(parts[i], nodes); } return nodes; } function getSelectedNodes(select, elements) { var result, node, nodes = []; var classname = (/\.([a-z0-9_-]+)/i).exec(select); var identify = (/\#([a-z0-9_-]+)/i).exec(select); var tagName = select.replace(/(\.|\#|\:)[a-z0-9_-]+/i, ''); for(var i=0; i<elements.length; i++) { result = tagName? elements[i].all.tags(tagName):elements[i].all; for(var j=0; j<result.length; j++) { node = result[j]; if((identify && node.id != identify[1]) || (classname && !(new RegExp('\\b' + classname[1] + '\\b').exec(node.className)))) continue; nodes[nodes.length] = node; } } return nodes; } </script>
2、在html页面中加入
<style type="text/css"> body {behavior:url(style/csshover.htc);} .a img:hover{ opacity:0.45;filter: alpha(opacity=45)} </style>
(注意下路径)
然后就可以啦
