The FVTermSession object and a set of javascript prototypes are provided in the FVTermParent.js file found in the FVTerm/Scripts folder.
FVTermSession contains a number of formal functions that are part of a call-back framework (such as OnLoad) as well as some useful helper functions defined to make it easier to interact with the FVTerm session object.
The FVTermSession class, as implemented, can be treated as a sample or utilized directly. When utilized directly, you can override individual function prototypes by re-declaring them in your javascript after the inclusion of FVTermParent.js in your HTML page, or use the events that are supported as documented in the following sections.
The key members are defined in the following sections:
•ConnectFVTerm Factory Function -- connect a new session
•Events
oonnewscreen - triggered each time a new screen is updated from the host
oonchange - triggered each time the user changes field with 5250 or 3270 host
