Question

I have this for loop, and it seems to be repeating the first loop twice (x=0) and then not doing the last one (x=2)

for (x=0;x<=2;x++)
    {
        if (document.getElementById("sub"+catCount+x).value != "")
        {
            if (nonums.test(document.getElementById("sub"+catCount+x).value))
            {
                total = total + parseFloat(document.getElementById("sub"+catCount+x).value);
            }
        }
        alert(x);
    }

In other words, I get two alert boxes with “0” in them, then one with “1” in it, and that’s it.

Can anyone tell me what I’m not seeing here? Why doesn’t it just progress through the loop normally (0,1,2)?

Answer 1

that is literally the only spot I use
the variable x on any page.

It works for me.

for (x=0;x<=2;x++)
{
  alert(x);
}

You can test it at console.
