need help with the FOR i=0.. case

[namemattersnot]

Re,

I have the following vars:

resp.date1 = "date1"';
resp.date2 = "date2";
resp.date3 = "date3";
resp.date4 = "date4";

I do a simple for " (i=1;i<4;i++) { alert('resp.date'+i); } " but it
alerts with "resp.dateNUMBER", instead of the var's value.

How do I accomplish this?

Thanks!

remove the quotes around resp.date

someone suggested the following solution that works:

b = 'a = resp.date'+i;
eval(b);
alert(a);

Vivek, it will not help becase it will try to ADD "i", instead of
appending it.

I found the working solution. Thanks for the answer though.

Hopefully you are declaring 'i' as a local variable:

for (var i=1; i<4; i++) ...

alerts with "resp.dateNUMBER", instead of the var's value.

Use:

alert( resp['date' + i] );

someone suggested the following solution that works:

Then 'someone' should not be trusted.

b = 'a = resp.date'+i;
eval(b);
alert(a);

As (almost) always, there is absolutely no need for eval, use:

alert( resp['date' + i] );
