Personal Entry - 4

I had a kind of interesting idea last night. I got bored, and decided to write a set of javascript functions that would allow programmers to fade something from one color to another. I don't mean that this would allow them to create a gradient. I mean that this would allow them to change the color of an element from one color to another with a kind of fading transition between the two colors. It's kind of a niche need, and it's not really very complicated, but I still had fun with it.

The first step is to get the current color of the element.

In IE, you can do this by calling: color = colorBlock.currentStyle.color;

In Firefox, you get the color by calling: color = document.defaultView.getComputedStyle(colorBlock, '').getPropertyValue("color");

IE returns the color in whatever format you entered it, so if you gave it a hex color, IE returns the color in hex, and if you gave it an RGB color, it returns the color in RGB. Firefox converts all colors to RGB, and always returns the color in RGB. Continue reading "Javascript Color Fader"
