conditional operators and jQuery

[Bryce Martin]

I have this if condition block...

if ($('.purchaseOrder:first').next().html() != "")
{
$('.purchaseOrder').toggle();
}

I would like to plop it into one line with conditional operators...is this possible?

This didn't work...

$('.purchaseOrder:first').next().html()!="" ? $('.purchaseOrder').toggle();

Can this be done?

The JavaScript syntax is not correct. With the ternary operator, you cannot omit the "else" clause.

It's also considered bad form to replace an if statement with the ternary operator unless you are conditionalizing the return of a value.

For example:

var z = (x==null) ? 0 : x;    

If you want to plop your example into one line, the following is preferred:

if ($('.purchaseOrder:first').next().html() != "") $('.purchaseOrder').toggle();

Thanks for the quick response Bear. I've never used conditional operators. I've always opted for the more wordy approach but thought I might give it a shot to learn something new today. I learned something new, looks like wordy is the way to go with this one. Thanks for the clarity, I understand them much better now.
