Option

Definition: An Option object is automatically created for each option tag within each select on a web page This is not a reserved word so you can declare your own variable or function called Option but if you do then you will not be able to access the options on the page from JavaScript through this object. Note that you can also add new options to existing select lists by creating Option objects and so keeping this object available for its predefined use will make adding options dynamically much easier. If you do override this with your own definition of Option then you will still be able to access and add Options to select lists but will need to use the much longer standard DOM calls to do so.
