conditional-comments

问题 When researching JavaScript conditional comments for IE, I stumbled upon @cc_on. This seems to work. However, the wikipedia entry on conditional comments provides the following code for more robust IE detections, specifically IE6: /*@cc_on @if (@_jscript_version > 5.7) document.write("You are using IE8+"); @elif (@_jscript_version == 5.7 && window.XMLHttpRequest) document.write("You are using IE7"); @elif (@_jscript_version == 5.6 || (@_jscript_version == 5.7 && !window.XMLHttpRequest))

问题 I am currently developing a theme for a homepage but ran into a few problems. For whatever reason I have no access to editing the html code itself, and I need to write custom .css for IE (specifically versions below IE9). I have "two" issues. First one is dual backgrounds. Versions below IE9 can't seem to render them flawlessly. If IE skips the element, this is fine but since the graphic in this element co-works with another element (for a smooth graphical transition), it makes the other

问题 I've noticed that in JSF 2.1.* my IE conditional comments are no longer working. Various characters are being replaced by HTML entities & invalidating the comment syntax. BalusC has pointed out a solution to the problem in another question which uses h:outputText. My problem is that I want my conditional comments at the top of my page, around the first element. This means that I can't use h:outputText as I haven't defined it's namespace yet. I believe that's correct anyway. Here's a code

问题 I am using the following IE conditional comment: <!--[if gt IE 7]> Here is some code. <![endif]--> This works great to keep the code from rendering in any IE lower than 8. However, this also keeps the code from rendering in Chrome and Firefox. Any ideas on why this is happening, and how I can get the code to render in browsers other than IE? 回答1: Conditional comments are a Microsoft IE-specific rule, and they are not part of any standard. If you check the structure of a conditional comment: <

问题 I don't want to use a couple of javascript plugins for IE 6/7. But I want to use them for all other browsers. How can I do it? Is there any way I can do it? 回答1: From the Wikipedia article on conditional comments (modified to fit your version requirements): <!--[if gt IE 7]><!--> <p>This code displays on non-IE browsers and on IE 8 or higher.</p> <!--<![endif]--> The weird markup in the first line serves to make the markup standards compliant. 回答2: Your question would be better phrased as

问题 For Internet Explorer 8 (IE8) I'd like to use the following CSS: color : green; I would like to apply a hack which only affects IE8, not to IE9, IE6 and 7. 回答1: Use conditional comments in HTML, like this: <!--[if IE 8]> <style>...</style> <![endif]--> See here: http://www.quirksmode.org/css/condcom.html You can test for IE versions reliably and also be sure other browsers won't be confused. 回答2: Use media queries to separate each browser: /* IE6/7 uses media, */ @media, { .dude { color:

问题 I'm trying to use an IE conditional comment to declare a CSS resource: <h:outputStylesheet name="common.css" library="css" /> <!--[if IE]> <link rel="stylesheet" type="text/css" href="#{resource['css:ie.css']}" /> <![endif]--> However, that doesn't seem to work. I'm seeing this in my generated HTML output: <link type="text/css" rel="stylesheet" href="/context/faces/javax.faces.resource/common.css?ln=css" /> <!--[if IE]> <link rel="stylesheet" type="text/css" href="/context/faces/javax.faces

问题 I'm using the new Internet Explorer 11 developer tools to switch the document mode to "8", but conditional comments are still ignored, that is, they are not properly parsed and behave like normal comments. So any referenced file inside the conditional comment is not requested/loaded by the browser. Why does this happen? Is it a bug? If you think that this is indeed a bug that needs to be fixed, please go in and say that you too can reproduce this on the Microsoft bug report that is reported

问题 This question already has answers here : Check if user is using IE (29 answers) Closed 14 days ago . In order to detect IE most Javascript libaries do all sort of tricks. jQuery seem to add a temporary object into your pages's DOM to detect some features, YUI2 does regex on the user agent in its YAHOO.env.ua = function() (file yahoo.js ) After reading this answer it came in my mind that it's true, in order to detect simply IE in Javascript we could simply add to our pages: <!--[if IE]><script
