Question

I have a nested for loop that creates a empty string value that represents a multidimensional array. Once the for loops have finished the result is something like this:

"[[0,0,0,0],[0,0,0,0]]"

I would like to add this to a multidimensional array within my code, how would i do this?

I have tried:

map = eval("[[0,0,0,0],[0,0,0,0]]");

but this does not produce the correct multidimensional array i am looking for.

I am looking to be able to use the array like this:

map[0][1] == 1;

Thanks

You could parse the string using JSON.parse() (MDN docu).

var str = "[[0,0,0,0],[0,0,0,0]]";

var map = JSON.parse( str );

However, in your example there is no entry equaling 1, so you requirement map[0][1] == 1 wont be fulfilled that way.
