META Tags

Javascript

<!-- The Application META Tag is an action tag used to adjust the running state of PocketBrowser applications. --> <!-- <META HTTP-Equiv="Application" Content="Quit"> --> <!-- Quits PocketBrowser --> <!-- <META HTTP-Equiv="Application" Content="Minimize"> --> <!-- Minimizes PocketBrowser --> <!-- <META HTTP-Equiv="Application" Content="Restore"> --> <!-- Restores PocketBrowser to full screen -->

<script> /* The Application META Tag is an action tag used to adjust the running state of PocketBrowser applications. */ function doApplicationInit() { var objGeneric = new ActiveXObject("PocketBrowser.Generic"); //objGeneric.InvokeMETAFunction('Application', 'Quit'); /* Quits PocketBrowser */ //objGeneric.InvokeMETAFunction('Application', 'Minimize'); /* Minimizes PocketBrowser */ //objGeneric.InvokeMETAFunction('Application', 'Restore'); /* Restores PocketBrowser to full screen */ } </script>

Modules return information back to their web pages via retrieval tags, for example the scanner has a retrieval tag called 'DecodeEvent' which is called whenever it decodes a barcode. To register to receive a retrieval tag call the module as follows:

<META HTTP-Equiv="[Module]" content="[RetrievalTag]:url('[URI]')">

So to register to retrieve the Scanner's DecodeEvent the following syntax would be used:

<META HTTP-Equiv="Scanner" content="DecodeEvent:url('Javascript:doScan('%6', '%s', %3, '%2');')">

Retrieval tags return information by replacing the text in place holders, defined as '%s' or '%<number>'. Each place holder represents 1 return value with '%s' being populated sequentially or '%<number>' providing direct acces to the desired value.

If the content for the Scanner's DecodeEvent is:

"url('Javascript:doScan('%6', '%s', %3, '%2');')"

The function would be called as follows:

"Javascript:doScan('Decode', '5449000053879', 0x35, 'SCN:EAN13');"

ApplicationEvent

The ApplicationEvent is triggered when a PocketBrowser application is minimized or restored.

ID	Name	Description
1	Application State	"Minimized" or "Restored"

<!-- <META HTTP-Equiv="Application" Content="ApplicationEvent:url('JavaScript:fnJSCallbackHandler('%1');')"> -->

<script> /* function doApplicationInit() { var objGeneric = new ActiveXObject("PocketBrowser.Generic"); //objGeneric.InvokeMETAFunction('Application', 'ApplicationEvent:url('JavaScript:fnJSCallbackHandler('%1');')'); /* The ApplicationEvent is triggered when a PocketBrowser application is minimized or restored. */ } </script>
