How do I make IE9 emulate IE7?

阅读更多关于 How do I make IE9 emulate IE7?

问题 I used: <meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7" /> in the header to force IE8 to emulate IE7. Will it do the same thing for IE9? I don't have IE9 and I'm running XP so can't install it to find out. If anyone with IE9 can test this page for me, I'd greatly appreciate it! It's a mootools slideshow and works with every browser I've tried it on including IE8. Arrows should change the photo, the thumbnails should scroll back and forth. http://ianmartinphotography.com/test-site

How to use feature detection to know if browser supports border-radius? (Including IE9)

阅读更多关于 How to use feature detection to know if browser supports border-radius? (Including IE9)

I've seen plenty of examples for detecting support for border radius using something like: var cssAttributeNames = ['BorderRadius', 'MozBorderRadius', 'WebkitBorderRadius', 'OBorderRadius', 'KhtmlBorderRadius']; for (var i = 0; i < cssAttributeNames.length; i++) { var attributeName = cssAttributeNames[i]; if (window.document.body.style[attributeName] !== undefined) { this._useCss = true; break; } } But this doesn't seem to work for IE9, which does support border-radius. Am I missing something? Got it - the detection array needs 'borderRadius' added - it's case-sensitive. Modernizr is a

IE9 HTML5 placeholder - how are people achieving this?

阅读更多关于 IE9 HTML5 placeholder - how are people achieving this?

I'm trying to use the placeholder="xxx" attribute in my web application, and I don't want to have a special visual for IE9. Can people throw out some good suggestions for achieving this functionality in IE9? I've found a couple links on here but none of the suggested scripts were sufficient... and the answers were from mid-2011, so I figured maybe there is a better solution out there. Perhaps with a widely-adopted jQuery plugin? I do not want to use anything that requires intrusive code such as requiring a certain css class or something. Thanks. EDIT - I also need this to work for password

Anyone know why this :after CSS isn't working in IE9?

阅读更多关于 Anyone know why this :after CSS isn't working in IE9?

This submit button should be rounded on the left side, and pointed on the right side. It's working in non-ie browsers, but in IE9, it is not working. If I look at the styles in the developer tools, the .flat-button:after rule has everything crossed out, as if it is superseded by something. What? <button type="submit" class="flat-button">Submit</button> <style> .flat-button { float: left; position: relative; border-top-left-radius: 5px; -moz-border-top-left-radius: 5px; -webkit-border-top-left-radius: 5px; border-bottom-left-radius: 5px; -moz-border-bottom-left-radius: 5px; -webkit-border

Does IE9 RTW support the placeholder attribute on input elements?

阅读更多关于 Does IE9 RTW support the placeholder attribute on input elements?

A bunch of sites mention support in IE9, but I assume this was something that appeared in the Betas, or RC. It doesn't appear to be supported in IE9 final. Can someone confirm this? No, placeholder text for form elements was never implemented for IE9. It is easily (and commonly) done with JavaScript. Placeholder support was added in IE10 . 来源： https://stackoverflow.com/questions/5329175/does-ie9-rtw-support-the-placeholder-attribute-on-input-elements

IE9 array does not support indexOf

Based on http://ie.microsoft.com/testdrive/HTML5/ECMAScript5Array/Default.html , I thought IE9 supports indexOf in array but the following breaks. Any idea why? <script type="text/javascript"> var a = [59, 20, 75, 22, 20, 11, 63, 29, 15, 77]; var result = a.indexOf(32);// document.write(result); </script> Error message as below: SCRIPT438: Object doesn't support property or method 'indexOf' test.php, line 9 character 1 Are you sure your page is running in IE9 mode? Check in dev tools (F12). If you have old DOCTYPE you might be seeing your page in IE8/7 mode, so indexOf is not supported. If you
