HTML/JavaScript Examples
The following example enables the scanner to read tlc39 labels:
<META HTTP-Equiv="scanner" Content="allDecoders:disabled">
<META HTTP-Equiv="scanner" Content="code39:enabled">
<META HTTP-Equiv="scanner" Content="tlc39:enabled">
<META HTTP-Equiv="scanner" Content="enabled">
Above example can also be written as shown below:
<META HTTP-Equiv="scanner" Content="allDecoders:disabled;code39:enabled;tlc39:enabled;enabled">
Or:
function enableTlc39()
{
scanner.allDecoders = 'disabled';
scanner.tlc39 = 'enabled';
scanner.code39 = 'enabled';
scanner.enable();
}
The following example enables the scanner to read all labels except tlc39:
<META HTTP-Equiv="scanner" Content="allDecoders:enabled">
<META HTTP-Equiv="scanner" Content="tlc39:disabled">
<META HTTP-Equiv="scanner" Content="enabled">
Above example can also be written as shown below:
function disableTlc39()
{
scanner.allDecoders = 'enabled';
scanner.tlc39 = 'disabled';
scanner.enable();
}
