The answer appears to be that a second set of ‘ ‘ are needed for the
conditional:
>’ (row[19] ? ‘ ‘ + row[19] + ‘ ‘ : ‘N/A’) + ‘<
Instead of:
>’(row[19] ? ‘ + row[19] + ‘ : ‘N/A’) + ‘<
The first way works with both Boolean and null checks, whereas the second
way works properly only with Boolean.
Sorry to use up to much list-time to answer my own questions, but
hopefully
this will help someone as an “impromptu tutorial”…

Well..another unexpected result…
When the inline conditional:
>’ + (row[19] ? ‘ + row[19] + ‘ : ‘N/A’) + ‘<
is used when a **value is present** in row[19], I get this as the output:
+ row[19] +
instead of the actual value.
If I remove the quotes from ‘ + row[19] + ‘, I get a syntax error.
However, if **no value is present** in row[19], I get
N/A
as the output, which is expected.
So, the conditional is working if no value is present, but outputting
the literal string
+ row[19] +
if a value is not present.
Assistance in understanding, anyone?
Thanks,

Well…to answer my own question…I found this works:
out.push('<li><span class="spanLeft">Pet Deposit</span><span
class="spanRight">' + (row[19] ? ' + row[19] + ' : 'N/A') +
'</span></li>');
But how does the conditional know whether a Boolean is being checked,
as in:
>’ + (row[19] ? ‘Yes’ : ‘No’) + ‘<
Or whether the presence of a value is being checked, as in:
>’ + (row[19] ? ‘ + row[19] + ‘ : ‘N/A’) + ‘<
What’s the logic that’s occurring behind the statements to differentiate?
Thanks for any insight…

I was shown how to use this inline condition for creating yes/no
Boolean values instead of
the normal true/false values javascript uses:
<span class="spanRight">' + (row[20] ? 'Yes' : 'No') + '</span>
I’d like to know if there’s an equivalent inline method for providing
a default value
when no value is present, such as:
<span class=”spanRight”>’ + (row[20] ? ‘NORMAL ROW[20] VALUE’ : ‘N/A’)
+ ‘</span>
Basically, if there’s no value in the current row as position 20, then
just us ‘N/A’.
Is this possible with a simple inline condition, too?
Thanks,
Rick
