I’ve developed a cross-browser Range and selection library called Rangy. Its core is not dissimilar in concept to IERange but goes beyond it in terms of implementation of the DOM level 2 Range and HTML5 selection specifications, and also in terms of stability and workarounds for browser bugs. I think it’s the best there is … Read more
Yes, you can safely assume undefined will get moved to the end of the array. From MDC: In JavaScript 1.2, this method no longer converts undefined elements to null; instead it sorts them to the high end of the array From the spec, 15.4.4.11 : Because non-existent property values always compare greater than undefined property … Read more
Here is a good example for styling native player controls(just tested in Chrome): https://codepen.io/BainjaminLafalize/pen/GiJwn To change the width of the player controls bar: video::-webkit-media-controls-panel { width: 40px; }
What about the case where the links are being generated while the page is being used? This occurs frequently with today’s more complex front end frameworks. The proper solution would probably be to put the click event listener on the document. This is because events on elements propagate to their parents and because a link … Read more
There’s an easier way that’s been around longer… use window.frames to get a reference to the frame’s window object. By name or id: var iframe_doc = window.frames.my_iframe.document; or if you prefer: var iframe_doc = window.frames[‘my_iframe’].document; or by index: var iframe_doc = window.frames[0].document; Good reference for window.frames here: http://developer.mozilla.org/en/DOM/window.frames An excerpt: each item in the window.frames … Read more
Is it broken? Well, sort of. I tried various ideas and couldn’t get the code in your jsFiddle to work. Looking at this MSDN Blog post, we find that postMessage only works between IFrames in older versions of IE, which has yet to be fixed for IE 11. That article links to a demo of … Read more
As Douglas said earlier, browsers try to clone previous tag when customer starts a new paragraph on an editable page. The discrepancy occurs when browser has nothing to depart from – e.g. when initially the page body is empty. In this case different browsers behave differently: IE starts to wrap every string into <p> tag, … Read more
The short answer: IE11 is the first version of Internet Explorer to support the direct usage of .png and .gif file format favicons. Why the confusion? As you mentioned, some seem to have implied that .png favicons are supported in IE7+, while others have stated the opposite. I believe the confusion is caused by the … Read more
jQuery’s attr() method is misleadingly named, badly documented and hides a very important distinction: the difference between attributes and properties, something which appears to be poorly understood by many web developers, particularly those whose introduction to JavaScript has come from jQuery. If you read no further, just take this away: you will almost never need … Read more
I’ve rewritten your code in plain JavaScript, to make it more independent on jQuery. The core functionality hasn’t changed. Fiddle: http://jsfiddle.net/EmjQG/2/ function cached(url){ var test = document.createElement(“img”); test.src = url; return test.complete || test.width+test.height > 0; } var base_url = “http://www.google.com/images/srpr/nav_logo80.png” alert(“Expected: true or false\n” + cached(base_url) + “\n\nExpected: false (cache-busting enabled)\n” + cached(base_url + … Read more
