A Javascript program may accompany an HTML
document or be embedded directly in it. The program executes in your browser
when the document loads, or at some other time such as when a link is
activated.
Javascript programs offer a means to extend HTML documents
in highly active and interactive ways. For example Javascript programs may:
- be evaluated as a document loads to modify the contents of the
document dynamically.
- accompany a form to process input as it is entered.
Parts of a form may dynamically be filled out based on the values of other fields.
Input data may also be ensured to conform to predetermined ranges of values,
that fields are mutually consistent, etc.
- be triggered by events that affect the document, such as
loading, unloading, element focus, mouse movement, etc.
- be linked to form controls (e.g., buttons) to produce graphical
user interface elements.
JavaScript must be enabled in order for you to use
all of our available facilities including Google Maps and other
Ajax applications.
You may enable JavaScript by either installing the latest version of your preferred
browser and/or changing your browser security options to their default values.
In Internet Explorer you may configure your browser
to evaluate Javascript programs by either going to:
- Tools > Internet Options > Security tag > Default level > OK, or
- Tools > Internet Options > Security tag > Custom level… > Scripting > Active Scripting > Enable > OK
