Re: Create a string dynamically to reference a property of an object?

Jonas,

> varString="document.getElementById.('inBox"+x+"').checked";

Remove the "." just infront of the "(" and try again.

Hint: When something doesn't work /go back to the simpelest form you know/ -
in this case trying to execute it directly, and with any additions like
dynamic ID names:

console.log("***"+ document.getElementById.('inBox0').checked );

The above wil fail too, due to that extra ".".  But with a bit of luck (and
the right tools, which you already seem to use) you will get a lot more info
about /what/ is going wrong, and can repair it yourself.

And by the way:  I hope you do realize that the element id you are using
itself is, after you create that string, not dynamic but hardcoded.

Ackk .. I just remembered something ...

And #&$&*^$ @ !!

Forget that.   I just realized that your explanation was inprecise enough to
make me think your "object property references" was referring to the
".checked" part.   Looking at your previous (differently named, so a bit of
a gamble) post thats not quite likely.    Give yourself a "well done" slap
on the shoulder, you just made me waste my time. :-(

And that also means that if that element id is the /only/ thing thats
dynamic you do not even need to go thru storing it into a variable and than
eval-ing it.    It will work perfectly whe you use it directly:

x=1
var myVar = document.getElementById('inBox'"+x+"').checked;

So much for not first trying the simpelest approach first, eh ? <whistle>
:-)
