Now I want to remove some of the files, but I don't know how, or if it's even possible. Preferably I'd like to just delete them from the FileList; I've g...
I'm loading image tags via AJAX and inserting them with the conventional .html(content) function in jQuery alongside a bunch of other HTML. However, this question still applies if you're loading a page from scratch. Now, I have a background image placeholder to be put there while the image loads.

It creates Javascript timeouts used for showing the next question in a series of time-limited questions. This isn't real code because it is obfuscated beyond all hope.

I'm creating a script that allows me to launch pop-in windows based on the URL's hashtag. I'm able to get it to work when the user plugs in the URL+hash directly in the location bar.

I want to convert an integer into its character equivalent based on the alphabet. For example: 0 => a 1 => b 2 => c 3 => d etc. I could build an array and just look it up when I need it but I'm wondering if there's a built in function to do this for me? All the examples i've found via Google are working with ASCII values and not a cha...
