Javascript setTimeout issue w/ for loop

Question

This is my function, when called the related node turns red and then does nothing.
Here is the javascript:

function blink (node, flickers)
{
    originalColo         


        

Answer 1

i is "i when the anonymous function is called" not "i when setTimeout is called".

You need to create a closure and pass the current value of i into it.

function ChangeColorLater(i) {
    return function () {
        ChangeColor (node, (((i%2) == 0) ? (originalColour) : ('red')))
    }
}

setTimeout (ChangeColourLater(i), (i*200));
