$p (Page Framework Core)

The purpose of this module is to ensure all sub-modules are initialized, including a call to a possible implementer-provided $p.init() method. In order to do this, it uses the .onReady event method to call pre-init functions in each module. After this, it checks if $p.init() exists, and calls it if it does.

Pre-init methods should be provided by the developer of sub-modules. these are simply function definitions named _init in the root of each module – for example: $p.gui._init().

The way that the call to these sub-items’ _init() methods is implemented, it binds this object to the object they belong to. This allows the developer to simply refer to object members using this (e.g. this.myFunction(), etc.).

The global init method is called after the pre-initialisation phase is finished. This function can be implemented as follows:

$p.init = function() {
  …
}

Note:

Both, the pre-init and the global init functions are called without parameters. Some modules may however require a secondary init, for which the implementer has to provide parameters. Please read the manuals for the used modules for more information.
