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();
}
