Hi Folks!
This is my first post in this forum so excuse me any incovenience.

I am getting this error with firefox with the script below:
Error: document.getElementById(img) has no properties

<—————
function MostrarMenu(div)
{
EsconderTudo();
menu = “Menu” + div;
img = “Img” + div;
img_over = “images/btn_” + div + “_over.gif”
document.getElementById(img).src = img_over;
document.getElementById(menu).style.display=”;
}
function EsconderMenu(div)
{
menu = “Menu” + div;
img = “Img” + div;
img_out = “images/btn_” + div + “_out.gif”
document.getElementById(img).src = img_out;
document.getElementById(menu).style.display=’none’;
}
function EsconderTudo()
{
EsconderMenu(“festival”);
EsconderMenu(“galeria”);
}

@JPnycDec 19.2005 — Could you please post the relevant HTML here? I hate sites that play music at me.

@pcofauthorDec 19.2005 — Sorry.... hehehe but this is just a preview!

We intend to play the songs only if the users click on PLAY button.

Here is the HTML:

Thanks for your help!

@JPnycDec 19.2005 — Well you have no elements with an ID of either img, or menu. The getElementById method requires that some element have the ID assigned to it that you pass to the function. Also, the id must be in quotes; getElementById('id')
Copy linkTweet thisAlerts:
@JPnycDec 19.2005 — Alternatively you can also pass the ID in the function call but you don't appear to be doing that either

@pcofauthorDec 19.2005 — I didn't get the point.

I put the id inside quotes but it didn't work. I am still getting an error message inside firefox. In IE everything is working fine.

Another doubt:

I am using a javascript to resize automatically an iframe. Everything is perfect but inside this iframe I would like to put another iframe and resize it automatically again. The script works but only if I refresh the page.

Thanks again.

Success!
