Cycling through variables

[drewson]

I am loading a number of variables from a text file:
news1
news2
news3
...

I want to cycle through them to manipulate their values until I get to the last defined variable (so I can put as many variables in the text file as I please. I've tried using a for loop, but I think I've got the wrong syntax:

for (i = 1; ["news" + i] != undefined; i = i + 1 ){
<manipulation steps here>
}

Any ideas?

Thanks!

add one more varaible to the text file...NumItems (say)

use loadvars for the text file

then as part of the onload function

numitems =mydata.NumItems;
mydata the loadvars object

for(1=0;1<numitems;i++){
<manipulation steps here>
}

I'm trying to find a way that I don't have to specify the number of variables to cycle through (kind of like using an end of file method in VB). If I'm right, NumItems would be a variable that contains the number of variables? Is there any other way?

 

[billwatson]

just use one variable in the text file and have a delimiter ( the | key perhaps)

then in flash

once varaible has loaded using

split(&quot;|&quot;

will put each variable in as an element of an array

you can then use the array length arguement instead of the extra variable numitems in the for statement
