$("#input").keyup(function(){ console.log($(this).val()); }) Problem is when one is typing slowly "a" & "b" the above code will result in "a","b" in console log. But when somebody does it quickly the result is "ab","ab". It's easier to do with letters which are near on a keyboard eg. "e"&"r". How to avoid it? Events keydown and keypr...

I'm using galleriffic to handle my image gallery and I'm having a problem with the thumbnail active states. Galleriffic doesn't have support for active states on the images - only the list items.

I have a status page that I would like to periodically reload. Instead of coding a refresh action into the page itself, I would like to have a wrapper page handle the periodic reloading. Any such thing available off the shelf? Something I could use like this would be perfect: http://foo/automatic-page-reloader?interval=60&page=ht...
Hi In my application, I allow users to write plugins using JavaScript. I embed V8 for that purpose. The problem is that developers can't use things like HTTP, Sockets, Streams, Timers, Threading, Crypotography, Unit tests, et cetra. I searched Stack Overflow and I found node.js. The problem with it is that you can actually create HTTP...

Does executing javascript within a browser in 'strict mode' make it more performant, in general? Do any of the major browsers do additional optimisation or use any other techniques that will improve performance in strict mode? Edit: Since none of the major engines actually implement strict mode, I'll rephrase slightly: Is strict mode in...
I want to enable drag-and-drop behaviour on my Web application. I have an image I want to drag. The image is behind another one that has transparent sections so that you can see the image beneath it. I do not want to change the order of the images. My thinking is I should use another layer on top of both images that is transparent an...

When the link is clicked the hash is changed and new content is pulled in (the 'default' action of clicking a href is therefore disabled.) That part works just fine, but there is a problem.

JSON responses can be exploited by overriding Array constructors or if hostile values are not JavaScript string-escaped. Let's assume both of those vectors are addressed in the normal way. Google famously traps JSON response direct sourcing by prefixing all JSON with something like: throw 1; < don't be evil' > And then the rest of th...
