I'm relatively new to programming and I was wondering how I would convert an array:
[[0,0,0,0,0,0],
[1,1,1,1,1,1],
[2,2,2,2,2,2],
[3,3,3,3,3,3],
[4,4,4,4,4,4],
[5,5,5,5,5,5]];
into a string of comma and line-return delineated indices, like:
"0,0,0,0,0,0
1,1,1,1,1,1
2,2,2,2,2,2
3,3,3,3,3,3
4,4,4,4,4,4
5,5,5,5,5,5"
with a dynamic function? I've searched for an implode() function but I couldn't find anything. Thanks in advance!
private function joinArrays(array:Array):String
{
var result:String = "";
for each(var a:Array in array)
{
result += a.join() + "\n";
}
return result;
}
Or if you don't want the line break after the last line:
var result:String = "";
var length:Number = array.length;
for(var i:Number = 0; i < length; i++)
{
result += array[i].join();
if(i != length - 1)
result += "\n";
}
return result;
toString() is called is , so you could cut out the for entirely and just go with trace(array.join("\n")); this would also solve your terminating line break problemA simple .toString() will do the job !
var a:Array=[[0,0,0,0,0,0],[1,1,1,1,1,1],[2,2,2,2,2,2],[3,3,3,3,3,3],[4,4,4,4,4,4],[5,5,5,5,5,5]];
trace(">",a.toString());
//> 0,0,0,0,0,0,1,1,1,1,1,1,2,2,2,2,2,2,3,3,3,3,3,3,4,4,4,4,4,4,5,5,5,5,5,5
EDIT : As often, RegExp will save your soul : )
var a:Array=[[0,0,0,0,0,0],[1,1,1,1,1,1],[2,2,2,2,2,2],[3,3,3,3,3,3],[4,4,4,4,4,4],[5,5,5,5,5,5]];
var columns:int=11;//columns count
trace(a.toString().replace(new RegExp("(.{"+columns+"})(,?)","g"),"$1\n"));
//output :
//0,0,0,0,0,0
//1,1,1,1,1,1
//2,2,2,2,2,2
//3,3,3,3,3,3
//4,4,4,4,4,4
//5,5,5,5,5,5
function join_arr(arr) {
var newarr = [];
for (var i = 0; i < arr.length; i++) {
newarr.push(arr[i].join(","));
}
return newarr.join("\n");
}
Haven't tested it but should work :)
