concatenating a string and a number in flash ?

[devowen]

Hi,

I wonder if anyone can help here ? I know this is a pretty simple thing - but Im just getting into actionscript and Im stuck on one part of something I am trying to do.

Basically and exmaple of what I am trying to do is - I have three text boxes, txt1,txt2,txt3. I then have another layer with some actionscript on, where I have a loop, and in that loop I have a string with the value 'txt'. I am trying to tag the value of the loop counter on the end of that string, and then use the concatenated result as a reference to populate the relevant txt box.

I cant seem to get it to work though, it does not recognise the number on the end of the string ?

var str1 = "txt";

var i:Number = 4;
while (i <5) {
    var str2 = str1 + i;
	eval(str2).text = "hello";
    i++;
}

Any thoughts appreciated.

Thanks

Have a look at your code. It would work fine if you had a dynamic text field on the stage named txt4.

Another way to reference the text field would be to use the array access operator ([]).

this[str2].text = "hello";
