cross-browser

I'm using a code from here to paste images from clipboard on a page. It works fine in all browsers (Chrome, Firefox, Edge and Opera). The problem is: when the image is a PNG or GIF with alpha channel (transparent areas), the alpha becomes black in Firefox and Edge. Here's the code snippet ( or jsfiddle if you prefer ): document.getElementById('pasteArea').onpaste = function (event) { // use event.originalEvent.clipboard for newer chrome versions var items = (event.clipboardData || event.originalEvent.clipboardData).items; console.log(JSON.stringify(items)); // will give you the mime types //

On a web page, I need to test if there is a horizontal scrollbar or not (so that I programmatically change the css of some other element). Is there some way to get that information using jquery (or pure javascript)? I tested function isHorizontalScrollbarEnabled() { return $(document).width()!=$(window).width(); } but it does not seem to work with all browsers (does not work for example with a recent Samsung phone I tested). I need it to work with all browsers, including recent mobile devices. Thank you! EDIT 1 I tested the solutions provided by plalx and laconbass, tested IE8, Firefox, Chrome

Is there any single framework with which I can build a css3, html5 website that is compatible for all browsers including IE7 and later? Can http://html5boilerplate.com/ boilerplate help me in this? You will never get the IE7 or IE8 rendering engine to achieve full compatibility with HTML5, CSS3, and other modern technologies. They are simply not capable of it. However there are some hacks, tools and plugins which can get you part of the way. Tools like Modernizr will help you by allowing you to detect which features are supported, to give your site a chance to work around it. jQuery is a great

I'm just learingn mobile web development and thinking about task: Is there a way to make a videostream betwen iOS, Android and Browser. What architecture and technology it should use. I already read this quetion on SO Peer-to-Peer video from iOS to Android? but there is nothing about browsers. If it can't be p2p and crossplatfom at the same time. I thought i shoud use Red5 server or etc. or Xmpp So I'm asking your advice and opinion here. Any information would be valuable Yes, You can !!! There is new technology enforced by google is WEBRTC It is stands for "web real time communication" and is

So I'm working on a web app where a user will need to: provide a file full of data to work on save their results to a file All the manipulation is done in javascript, so I don't really have a need for server-side code yet (just static hosting), and I like it that way. In Firefox, I can use their file manipulation api to allow a user to upload a file directly into the client-side code (using a standard <input type=file/> ) and create an object URL out of a file so a user can save a file created by the client-side code. <input type="file" id="input" onchange="handleFiles(this.files)"> <a

I've been searching for this for a couple of days now and so far, the best I can come up with is checking the list below. I really don't like to check for support based on User-Agent, especially since it can be spoofed. I've also heard of at least one instance where the list below is incorrect (noted below). Is Internet Explorer? Is WebKit? (But I've read that mobile Safari doesn't support it) Is Opera? Is Gecko and version >= 1.9? (meaning Firefox 3 or later) Is there a better method based on testing for support directly via JavaScript, or is this pretty much the only way to test for support?

When programming in C++ against the browser's DOM each engine has a different set of interfaces, IE has the COM based [MSHTML]( http://msdn.microsoft.com/en-us/library/aa752279(VS.85).aspx) , Mozilla has the XPCOM based Gecko DOM etc. Is there a common API that has adapters for major browsers (and versions)? As a clarification, the application in question is a desktop application written in C++ which interacts with browsers, currently we have separate code bases for support of IE and Mozilla and I'm trying to reduce duplications of logic and allow adding new browsers with less effort.
