USE AND FUNCTIONING

Key press Metatags

The key press metatags can be used to call JavaScript functions. They have the

name structure: “DL_Key_xxx” where xxx is the VKey code.

Example:

Assigning a key press via a DL_Key metatag overrides its use on the page. For

instance, when entering data in a text box a character assigned as a DL_Key would

not be entered in the text box. Instead, the javascript action would occur.

Refer to the Microsoft website to find the list of all the possible Vkey codes:

Because DL_Keys persist past the page in which they were loaded,

the DL_Clear metatag is provided to clear the settings on subsequent

page loads.

NOTE

Scanning Metatags

DL_Scan – Captures scan results and sends barcode/tag value to a javascript

function on the web page.

If the “content=” value is a javascript function the device will be taken out of keyboard

wedge mode and start listening for scan events. A scanned barcode/tag result will be

used as an argument to that javascript function which is then invoked.

If the “content=” value is “Wedge” then the device will stop listening for scanned

event and enter keyboard wedge mode.

If the “content=” value is “Disable” then the device will stop listening for scanned

events but not enter keyboard wedge mode.
