Here’s a cross-browser function to get a computed style… getStyle = function (el, prop) { if (typeof getComputedStyle !== ‘undefined’) { return getComputedStyle(el, null).getPropertyValue(prop); } else { return el.currentStyle[prop]; } } You may store it as an utility within an object, or just use it as provided. Here’s a sample demo! // Create paragraph element … Read more
You can check codecs for different video types with HTMLVideoElement.prototype.canPlayType. There is also a great HTML5 feature detection library, Modernizr. var testEl = document.createElement( “video” ), mpeg4, h264, ogg, webm; if ( testEl.canPlayType ) { // Check for MPEG-4 support mpeg4 = “” !== testEl.canPlayType( ‘video/mp4; codecs=”mp4v.20.8″‘ ); // Check for h264 support h264 = … Read more
As far as I know, it’s not possible in IE because it uses the OS component. Here is a link where the control is replaced, but I don’t know if thats what you want to do. Edit: The link is broken I’m dumping the content <select> Something New, Part 1 By Aaron Gustafson So you’ve … Read more
There’s an excellent chart on wikipedia that lists common image types and their support by browser. The file types you listed (jpg, gif and png) seem to be the main formats supported by nearly every browser, albeit with certain caveats: Internet Explorer supports PNG images but is unable to correctly display images with gamma correction … Read more
Because reload() needs window.location as this. In other words – it is a method of window.location. When you say: var fun = window.location.reload; fun(); You are calling reload() function without any this reference (or with implicit window reference). This should work: setTimeout(window.location.reload.bind(window.location), 250); The window.location.reload.bind(window.location) part means: take window.location.reload function and return a function that, … Read more
I’ve been struggling with this issue. I wanted a reference to another window, so I was issuing a: otherWinRef = window.open(“”,”OtherWindow”); However when I issue this command, the browser will switch focus to the OtherWindow. I thought this could be addressed by doing this: otherWinRef = window.open(“”,”OtherWindow”); window.focus(); but the window.focus() has no effect. I … Read more
This is for ‘design mode’ where the browser effectively turns the document into an editor. The execCommand API originated with IE and was later added to HTML5. Exactly which commands are supported, as well as their behavior varies across browsers. Clipboard access is considered a security risk.
I don’t see a doctype declaration in your HTML, so I can only assume your test page is being rendered in quirks mode. Why would it fallback to px? Is pixel always a preferred unit? Is there any rule defined in W3C working draft or recommendation? It will only fall back to px in quirks … Read more
The Javascript session will struggle to continue it’s mission in the face of impending doom. Coding in this manner is considered unpredictable. …and cruel.
You can use Base64 data of an image.
