Question

this code http://jsfiddle.net/minagabriel/5MQ77/

     var flowShadeBigArray =[] ;
          var x = [7, 411, 780]
          var y = [286, 712, 1058]

        for( var i = 0 ; i< x.length;i++){

            for(var index = x[i]; index <= y[i] ; index++ ){

                 var temp = [] ; 

                temp.push(index) ; 
                flowShadeBigArray.push(temp); 


            }

        }
        console.log(JSON.stringify(flowShadeBigArray));

generate the following array

 [[7],[8],[9],[10],[11],[12],[13],[14]................[1056],[1057],[1058]]

i want to create a three arrays inside flowShadeBigArray and have the [x[i] ... y[i] ]
grouped together:

example

[  [  [7]....[286] ] , [ [411]...[712] ] ,[ [780]...[1058] ] ]

NOTE i still need to keep each of these numbers as an array so i can use it an an index for something else

THANKS

Just move the temp initialization to the first loop, before the second, and the .push() to the first loop after the second (or before, doesn’t matter).

var flowShadeBigArray = [];
var x = [7, 411, 780]
var y = [286, 712, 1058]

for (var i = 0; i < x.length; i++) {
    var temp = [];

    for (var index = x[i]; index <= y[i]; index++) {
        temp.push(index);
    }
    flowShadeBigArray.push(temp);
}

If each individual number belongs in its own Array, then change this:

flowShadeBigArray.push(temp);

to this:

flowShadeBigArray.push([temp]);
