Is there a more "Prototype" way to construct a variable key within
JavaScript, similar to what you can do in PHP? For example, in PHP, if
I had the string 'title' assigned to the variable $class, and I wanted
the current value of the variable $titles, I could construct a
'variable variable', which would point back to $titles:
$titles = Array('Gone with the Wind','The Wind in the Willows','Break
like the Wind');
$class = 'title'; //plain string
$key = $class + 's'; //concatenate for poor man's pluralize
echo ($$key == $titles) ? true: false; // => true
In JavaScript, Google tells me that eval() will do the same thing, but
I've heard over and over on this list that eval() is evil and to be
avoided. Any suggestions?
Thanks in advance,
Walter
