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
