JavaScript: Functions

Sometimes instead of just adding your javascript to the page and having the browser perform the tasks as soon as the script is read, you might want your javascript to be performed only upon the detection of a certain event. A function is a block of code which can be called from any point in a script after it has been declared. It is basically a compartmentalized JavaScript designed to accomplish a single task. Furthermore, JavaScript written into functions will not be performed until you specifically ask for it. This way you gain complete control of the timing. Functions are useful because they contribute to rapid, reliable, error-reducing coding, and increase legibility by tiding up complicated code sequences. More...
