Modules demo

These demos demonstrate the use of modules. There are 3 demos which basically do the same thing, just using different techniques.

Functionally the module offers 2 things:

• a way to clear HTML below a certain tag (identified by it's ID): the ClearPage function. the DefaultClearID variable is used to determine the HTML tag if no tag is specified in the ClearPage function.

• a way to set the HTML page's title which is visible in the tab caption or browser window title bar. This is done with the SetPageTitle function.

htmlutils

In the htmlutils demo, the 2 functions and a variable are exported:

• ClearPage
• SetPageTitle
• DefaultClearID

Classes

In the classes demo, the 2 functions and a variable are made part of a class THTMLUtils , and only a function to create an instance of this class is exported.

Exported:

• CreateUtils

ClassesUsingVar

In the classesusingvar demo, the function to create an object is removed and replaced by a variable that contains an instance of the THTMLUtils class. This variable is then exported.

Exported:

• Utils
