Question

Ok, so I have a array like this.

myArray:Array []

myArray.push(Object) // x 4. 

I have 4 objects in my array. Then I splice the second one. Leaving me with a array that looks like this. 1,3,4. Now… I would like to have this array look like this: 1,2,3. I Would like the 3 & 4 to simple switch place to one less from their own postion.

I know it’s possible, I had a friend do it for me some years ago. How do I do this?

Answer 1

I would like to have this array look like this: 1,2,3

So…just pop() the last element:

myArray:Array = [1, 2, 3, 4];
myArray.pop();
trace(myArray);  // Prints: 1,2,3

I Would like the 3 & 4 to simple switch place to one less from their own postion.

Umm…that’s exactly what deleting the second element already did…

If the end result you want is that the second element be placed at the end, that is:

Before: [1, 2, 3, 4]  --> After [1, 3, 4, 2]

Then you can do that in two steps:

var spliced = myArray.splice(1, 1); // Remove the second element and return it 
myArray.push(spliced);              // Push it to the end of the array

Technically you could do this in one step, since the splice will happen first:

myArray.push(myArray.splice(1, 1));
