converting int to string

Copy linkTweet thisAlerts:

Hi,

Am I doing something wrong with this code?

I have a for loop:

[CODE]
for( var i = 0; i < aInput.length; i++ )
[/CODE]

I want to use this i variable to concatonate it as a string to find an input box

[CODE]
var j = i;
var qualname = “discountqualifier” + j;
qualname.toString();

if ( inputName == ( qualname ) )
{
[/CODE]

Assuming I have a input box named discountqualifier0, discountqualifier1, discountqualifier2 etc…

Should this match or am I missing something?

Thanks,
Joe

NOW

if ( inputName == qualname )

@shifter480authorJun 26.2010 — The "discountqualifier" is a string but the j OR i is an int as I am using it in the for loop...

If I do this:

var qualname = "discountqualifier1";

then it will do as expected but

"discountqualifier" + j

will not???

Any ideas?

Thanks

var qualname = "discountqualifier1";
var qualname = "discountqualifier" + 1;
var qualname = "discountqualifier" + "1";They are all functionally equivalent. Only once do you have to be careful, when you want two numbers to become strings. Other than that, they will be automatically cast by the concatenation.

Success!
