"cannot assign" workaround?

[Don Lancaster]

I want to programically generate some JS variable names in a loop.

The variables are NOT to be array values.

The variable names might be eq0, eq1, eq2....

Inside an ii indexed loop,

eval ("eq" + ii ) = some calculated stuff ;

generates a "cannot assign" error.

So does

"eq" + 11 = some calculated stuff ;
What is the correct way to programatically generate variable names?

Stop mis-using eval.

window["eq" + ii] = //some calculated stuff

So does

"eq" + 11 = some calculated stuff ;

Assign them as properties of the window, which they are anyway, using
bracket notation.

OK, I know how it feels when someone you asked how to do something
tells you that you should do something else instead, though they might
be right at times, no point in not-answering your question too. Try
this:
eval( "eq" + ii + " = " + (some calculates stuff) + ";" );
that should work, though I didn't test it. The point is, you should
make the whole expression appear under eval();

You really should think outside of eval(). I realize you seem to be
intimately familiar with its use, but that might be telling a story
about the quality level of your code you may not wish everyone to realize.

If you are going to encourage its (mis)use, you should at least warn the
person you are replying to as to its improper use.
