Array Positions Into An Array

[adz1809]

Hi,

I have an array:

( 0, 1, 0, 0, 0, 0, 1, 0, 0, 0, 1, 1, )

and i need to find the positions of the 1's and place those positions into another array, eg.-

( 2, 7, 11, 12, )

Any ideas.

cheers

var arr = new Array( 0, 1, 0, 0, 0, 0, 1, 0, 0, 0, 1, 1 );
var arr2 = new Array();
for (var i=0; i<arr.length; i++){
    if(arr[i]==1)
        arr2.push(i+1);
}
for (var i=0; i<arr2.length; i++){
    alert(arr2[i]);
}
 

Should do ya.
