How 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

To build a website with powerful functions and good user experience, HTML alone is not enough. The following technology is also required: JavaScript gives web page dynamic and interactiveness, and real-time changes are achieved by operating DOM. CSS is responsible for the style and layout of the web page to improve aesthetics and user experience. Modern frameworks and libraries such as React, Vue.js and Angular improve development efficiency and code organization structure.

Boolean attributes are special attributes in HTML that are activated without a value. 1. The Boolean attribute controls the behavior of the element by whether it exists or not, such as disabled disable the input box. 2.Their working principle is to change element behavior according to the existence of attributes when the browser parses. 3. The basic usage is to directly add attributes, and the advanced usage can be dynamically controlled through JavaScript. 4. Common mistakes are mistakenly thinking that values need to be set, and the correct writing method should be concise. 5. The best practice is to keep the code concise and use Boolean properties reasonably to optimize web page performance and user experience.

HTML code can be cleaner with online validators, integrated tools and automated processes. 1) Use W3CMarkupValidationService to verify HTML code online. 2) Install and configure HTMLHint extension in VisualStudioCode for real-time verification. 3) Use HTMLTidy to automatically verify and clean HTML files in the construction process.

HTML, CSS and JavaScript are the core technologies for building modern web pages: 1. HTML defines the web page structure, 2. CSS is responsible for the appearance of the web page, 3. JavaScript provides web page dynamics and interactivity, and they work together to create a website with a good user experience.

The function of HTML is to define the structure and content of a web page, and its purpose is to provide a standardized way to display information. 1) HTML organizes various parts of the web page through tags and attributes, such as titles and paragraphs. 2) It supports the separation of content and performance and improves maintenance efficiency. 3) HTML is extensible, allowing custom tags to enhance SEO.

The future trends of HTML are semantics and web components, the future trends of CSS are CSS-in-JS and CSSHoudini, and the future trends of JavaScript are WebAssembly and Serverless. 1. HTML semantics improve accessibility and SEO effects, and Web components improve development efficiency, but attention should be paid to browser compatibility. 2. CSS-in-JS enhances style management flexibility but may increase file size. CSSHoudini allows direct operation of CSS rendering. 3.WebAssembly optimizes browser application performance but has a steep learning curve, and Serverless simplifies development but requires optimization of cold start problems.

The roles of HTML, CSS and JavaScript in web development are: 1. HTML defines the web page structure, 2. CSS controls the web page style, and 3. JavaScript adds dynamic behavior. Together, they build the framework, aesthetics and interactivity of modern websites.

The future of HTML is full of infinite possibilities. 1) New features and standards will include more semantic tags and the popularity of WebComponents. 2) The web design trend will continue to develop towards responsive and accessible design. 3) Performance optimization will improve the user experience through responsive image loading and lazy loading technologies.
