Java Script return column value?

Question

Can someone help with syntax on returning any specific column of an array in Google script / Java Script.

Array

01 02 03 04 05
06 07 08 09 10
11 12 13 14 15

2nd row of array...

Browser.msgBox(values[1]);

06 07 08 09 10

what's the syntax for returning values of 2nd column?

Are there simpler way without the for loop path, reason being I have a 7k row by 28 column array and trying to mak it more efficient via better call methods.

Answer 1

Browser.msgBox(values[x][y]);

Where x is the row, y is the column.

_{I don't know why you are getting the second row via 2 though. Arrays "zero-indexed". They start with 0 . You should be getting the third row with 2 .}

Answer 2

You can't get the values of second column directly, you will have to aggregate them manually.

Ex:

function getColumn(array, column){
    var result = [];
    for(var i = 0; i< array.length; i++){
        result.push(array[i][column]);
    }
    return result;
}

Then

var column2 = getColumn(myArray, 1)
