Question

I have a ternary ahead of variable instantiations. The problem is, that this is an incorrect way to assign a variable for an attribute.

$partial = $data.cell_info_box === undefined ? job_box : cell_info_box
$rel     = $($data.$partial).attr('rel');
$klass   = $($data.$partial).attr("rel").match(/job/) == null ? 'task' : 'job';

How can I provide my ternary like demonstrated but create callable attributes with my initial ternary’s product?

Based on your comment, what you want is $data[$partial]. This syntax is used when you want to get a value from an object without knowing the key name until runtime. You may also see this problem incorrectly solved through the use of eval but this is the correct way.
