"Help!

Is there a way to declare a variable name using other variables in
Javascript? In PHP, it's done with something like:

<?php
$var1 =3D "foo";
${$var1.bar} =3D "great!";
print $foobar;
// Outputs "great!"
?>

Is there a similar method in Javascript?

Thanks.

Are you sure that outputs "great!" ?

There's no need for eval (or evail):

var foo =3D "Value of Foo";
var bar =3D foo;
alert("foo =3D " + foo + ".\n\nBecause the value of the variable bar now
equals the value of the variable foo, bar also =3D " + bar + ", without
the need of eval.");
