You might try the splice function to drop a particular value from the array. Check the info about the splice function here.
// Given the following array:
var arr = [1, 2, 3, 4, 5, 6, 7, 8, 9, 0];
// Iterate through the array and test each value until we find the
// one we're looking for and remove it
for( var i = 0; i < arr.length; i++){
if ( arr[i] === 5) {
arr.splice(i, 1);
}
}
//=> [1, 2, 3, 4, 6, 7, 8, 9, 0] This is the value of arr after the splice
