var anarray = [0,1,2];
var anotherone = [3,4,5];
var more = [10.3,5.34,99];
For testing purposes, I'd like to re-define those arrays by reading new ones from a text file. If I were starting from scratch, I could do this by structuring my script differently, but I'm not. so lets say our text file has
anarray = [5,6,7];
anotherone = [8,9,7];
more = [100,102,103];
Now, I can use the File object in JS to read the lines, and for each line, separate these with some split() and maybe a bit of regexp, and end up with a variable that contains the array name, and the array itself. For example the first line could give me:
thename = "anarray";
tmparray = [5,6,7];
but I'm at a loss of how to actually populate the array "anarray" with the contents of tmparray based on the symbol "anarray".
I can do it if I'm strict in my textfile and setup a bunch of ugly case statements based on line number, but I'd rather be able to do this more elegantly.
