need some quick help with this little variable question | | |
hi, i am still figuring out joins and whatnot, could someone help me
achieve this goal?
<script>
var setnumber = 5;
var total5 = 100;
alert(total+setnumber);
</script>
Ok, the alert does not work, but my goal is to do what I hope is
obvious, and that is to join the setnumber value with the word
'total', so it becomes 'total5', and so it can be accessed/utilized as
such.
Can someone please help me with this? It would be greatly
appreciated. Have a very nice day.
Rebecca.

You are missing the type attribute (text/javascript.) Quote:

I don't see "total" defined. Quote:

alert('total' + setnumber);

to 100? | | | | re: need some quick help with this little variable question

alert('total = ' + window['total'+setnumber]);
there is also the function eval()
alert('total = ' + eval('total'+setnumber));

The other two answers tell us that your goal is not obvious.
You want to reference a variable whose name is partially
supplied in the value of another variable.
alert(window["total"+setnumber]);
will alert the value of total5, if setnumber=5.
Global variables are attributes of the window object (in a browser).
If your attribute name is the value of an expression, you can use
this "square bracket notation", to access it.
This makes the object look sort of like an associative array.

That would display "total5". However, it would see the OP wanted to
display "100":
window.alert(this["total"] + setnumber);
I recommend to use an array instead of numbered variables, though. Quote:

Do you ever read a thread before replying? It has been mentioned several
times before now that an array would work better for what the OP wanted. Quote: Quote:

Why would referring the OP to buy a book (via hint) be kidding?
BTW, your posting agent, newsserver or your setup is broken for you to
be posting your reply twice.
