JXtension - new Color(redValue, greenValue, blueValue)

Purpose:
Give the user the ability to represent and mutate a 24-bit color as a JavaScript object.

Parameters:

redValue	The amount of red that will compose the color. This value must be an integer greater than or equal to 0 and less than or equal to 255.
greenValue	The amount of green that will compose the color. This value must be an integer greater than or equal to 0 and less than or equal to 255.
blueValue	The amount of blue that will compose the color. This value must be an integer greater than or equal to 0 and less than or equal to 255.

Result:
Constructing a JXtension color in this way yields an object which keeps track of the RGB values.

Example #1:
The following will illustrate how to create a JavaScript (JXtension) color object from hexadecimal color codes:


// Randomize the order of the colors. var indices = [parseInt(Math.random() * 3)]; indices.push((indices[0] + parseInt(Math.random() * 2) + 1) % 3); indices.push(3 - indices[0] - indices[1]); // Get the cells below the text box. var tds = $("#tblEx1 TR:element(last) TD"); // Show red at a random spot. var aColor = new Color(255, 0, 0); $(tds[indices[0]]).setCSS("background-color", aColor); $(tds[indices[0]]).setCSS("color", aColor.getSafeColor()).setText(aColor); // Show green at a random spot. aColor = new Color(0, 255, 0); $(tds[indices[1]]).setCSS("background-color", aColor); $(tds[indices[1]]).setCSS("color", aColor.getSafeColor()).setText(aColor); // Show blue at a random spot. aColor = new Color(0, 0, 255); $(tds[indices[2]]).setCSS("background-color", aColor); $(tds[indices[2]]).setCSS("color", aColor.getSafeColor()).setText(aColor); // Show the message. alert("Notice how the three primary colors of light can be found in the cells b" + "elow the text box.");
