HomeWeb Front-endHTML TutorialHow to solve the incompatibility problem of div:hover in ie6_html/css_WEB-ITnose

像淘宝网www.taobao.com中分类有服饰、数码、护肤等,当鼠标移上去,div边框显示橙色的效果怎么弄出来的,div:hover在ff、ie7、ie8中都能实现,唯独ie6不能兼容div:hover,该怎样解决这个问题使得效果和淘宝网的这个一样在ie6中也可以实现该效果
 


回复讨论(解决方案)

<!--[if lte IE 6]><script type="text/javascript" language="Javascript" src="hover.js"></script><![endif]-->


/* 这个是普通样式,定义给需要效果的元素 */.hovereffect {border:1px solid blue;}/* 这个是hover样式 */.hovereffect:hover,.lay-on {background: #eee;border:1px solid red;}




<div class="hovereffect">div的hover</div><p class="hovereffect">p的hover</p>

ie6是css1.0,不支持非a的hover伪类,若想实现hover效果需要写js

将下面代码 写入htc文件中

/*解决ie6.0 的hover兼容问题*/<attach event="ondocumentready" handler="parseStylesheets" /><script>var csshoverReg = /(^|\s)(([^a]([^ ]+)?)|(a([^#.][^ ]+)+)):(hover|active)/i,currentSheet, doc = window.document, hoverEvents = [], activators = {    onhover:{on:'onmouseover', off:'onmouseout'},    onactive:{on:'onmousedown', off:'onmouseup'}}function parseStylesheets() {    if(!/MSIE (5|6)/.test(navigator.userAgent)) return;    window.attachEvent('onunload', unhookHoverEvents);    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(!csshoverReg.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, '.$2' + pseudo);        var className = (/\.([a-z0-9_-]*on(hover|active))/i).exec(newSelect)[1];        var affected = select.replace(/:(hover|active).*$/, '');        var elements = getElementsBySelect(affected);        if(elements.length == 0) return;        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;    hookHoverEvent(node, events.on, function() { node.className += ' ' + className; });    hookHoverEvent(node, events.off, function() { node.className = node.className.replace(new RegExp('\\s+'+className, 'g'),''); });}    function hookHoverEvent(node, type, handler) {        node.attachEvent(type, handler);        hoverEvents[hoverEvents.length] = {            node:node, type:type, handler:handler        };    }    function unhookHoverEvents() {        for(var e,i=0; i<hoverEvents.length; i++) {            e = hoverEvents[i];            e.node.detachEvent(e.type, e.handler);        }    }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 identify = (/\#([a-z0-9_-]+)/i).exec(select);        if(identify) {            var element = doc.getElementById(identify[1]);            return element? [element]:nodes;        }               var classname = (/\.([a-z0-9_-]+)/i).exec(select);        var tagName = select.replace(/(\.|\#|\:)[a-z0-9_-]+/i, '');        var classReg = classname? new RegExp('\\b' + classname[1] + '\\b'):false;        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(classReg && !classReg.test(node.className)) continue;                nodes[nodes.length] = node;            }        }                  return nodes;    }</script>


页面中添加引用
 body        {            /*        	首先不支持绝对路径,只支持相对路径。        	其次,是相对于当前ASPX网页的相对路径,和CSS文件的位置无关。             */            behavior: url(../css/hover.htc); /*可在IE6,7中对非<a>元素使用hover等伪类*/        }


可以用table模拟

也可以用jquery写:

<div class="test"></div>

<script type="text/javascript">$document.ready(function(){    $('.test').mouseover(function(){        $('.test').css({boder:orange 1px solid});    });    $('.test').mouseout(function(){        $('.test').css({boder:blue 1px solid});    });});</script>

自己测试了下,上楼的写法好像有点问题啊
<script> <br /> $(document).ready(function(){ <br /> $('.test').mouseover(function(){ <br /> $('.test').css({"boder":"orange 1px solid"}); <br /> }); <br /> $('.test').mouseout(function(){ <br /> $('.test').css({"boder":"blue 1px solid"}); <br /> }); <br /> }); <br /> </script>

2楼可以!谢谢。

感谢2楼的同学,我困惑了很久的问题得到解决
再次谢谢你,谢谢网络。

2楼  hover.js   里面怎么写的??

没必要搞得这么复杂,
div:hover{zoom:1;XXX你的样式} 
div:hover .xxxclass{XXX你的样式}

对了    ie6 相对css是1.0,只对a标签有hover有用,非a标签没用,但是css2.0中,基本所有的都可以。

我也遇到这个问题了啊~~不过重新引入一个文件来解决好麻烦啊~~希望有更简单的办法

用是会用了,就是写着就傻眼了

The official account web page update cache, this thing is simple and simple, and it is complicated enough to drink a pot of it.

After reading it, you can easily deal with various caching problems, allowing your users to always experience the freshest content. Let’s talk about the basics first. To put it bluntly, in order to improve access speed, the browser or server stores some static resources (such as pictures, CSS, JS) or page content.

The new version is online,
