Passing vars into preview

[zoobie]

I used to use document.form.graphic.selectedIndex to pass vars into my preview from a drop down box.

I've now changed the format whereas the var from the image viewer is passed into the form directly via document.form.graphic=g_xxx without selection from a drop down box.

What should I use for document.form.graphic.selectedIndex now?

Thanks :p

If you had:

whatever=document.form.graphic.selectedIndex


Then I would have thought:

whatever=document.form.graphic.value

May need to see the script for better idea

Let me explain from the top...

I have a image viewer on the page...and a seperate form. I used to have the form with a selection box to choose a graphic. This was called in my preview as
win.document.write('<center><img src="' + graphicURL[document.form.graphic.selectedIndex] + '"></center><br>');

I changed the arrangement around where now, when the "next" button on the imageviewer is clicked, the title of the image is passed into a textbox in the form automatically. However, it's not previewing because the image isn't being selected in the form anymore.

How do I fix the preview graphicURL above?


Imageviewer code:

g_fPlayMode = 0;
g_iimg = 0;
g_imax = 0;
g_ImageTable = new Array();

function ChangeImage(fFwd)
{
if (fFwd)
{
if (++g_iimg==g_imax)
g_iimg=0;
}
else
{
if (g_iimg==0)
g_iimg=g_imax;
g_iimg--;
}
Update();
}

function Update(){
document.all._Ath_Slide.src = g_ImageTable[g_iimg][0];
document.form.graphic.value = g_ImageTable[g_iimg][1]; // This is where the title is being passed into the form.
document.all._Ath_FileName.innerHTML = g_ImageTable[g_iimg][1];
document.all._Ath_Img_X.innerHTML = g_iimg + 1;
document.all._Ath_Img_N.innerHTML = g_imax;
}


function Play()
{
g_fPlayMode = !g_fPlayMode;
if (g_fPlayMode)
{
btnPrev.disabled = btnNext.disabled = true;
Next();
}
else
{
btnPrev.disabled = btnNext.disabled = false;

}
}
function OnImgLoad()
{
if (g_fPlayMode)
window.setTimeout("Tick()", g_dwTimeOutSec*1000);
}
function Tick()
{
if (g_fPlayMode)
Next();
}
function Prev()
{
ChangeImage(false);
}
function Next()
{
ChangeImage(true);
}
function main()
{

Update();
}
