4.12.1 Locked Web Browser Special Metatags

General Metatag Comments

A metatag is a special HTML tag that stores information about a Web page but

does not display in a Web browser. For example, metatags provide information

such as the program used to create the page, a description of the page, and

keywords relevant to the page.

As per the HTML specification, all metatags must be contained within a <head> …

</head> tag

set.

Also, the head tag set must be complete within the first 15K of the web

page.

The Datalogic Locked Web Browser defines some special metatags that allow the

web application to interact with the device:

In particular, the special metatags allow it

to:

enable/disable scan engine triggers

enable/disable specific symbologies in the scan engine

easily assign a key press to a javascript function.

Metatag settings of trigger enable, symbology enable, or DL_Key assignments

persist past the page in which they are loaded. The settings stay in effect until they

are changed by another metatag.

Trigger Metatag

DL_Triggers – “Enable” or “Disable” all triggers

If the page contains this tag, the triggers are enable or disable depending on the

“content=” value.

Example:

1 2 ... 105 106 107 108 109 110 111 112 113 114 115 ... 153 154
