Ok, I give up. Clearly the Yahoo rich text editor is having troubles
:( Or maybe it's the Google Chrome browser causing the grief?
For the sake of efficiency, I'd go with an if-else
instead of creating so many intermediary arrays (condition1,
condition2, condition3, resulting IIf) and executing 2 expressions
(condition2 and condition3 as per IIf behavior) instead of just 1. You
could break out the clauses to make the intent more evident.
if (condition1) {
if (condition2) {
...
}
} else if (condition3) {
...
}
