[SOLVED] hiding DIV till option in selectbox is selected

[acctman]

hi i'm using this code below to display an alert when a use select an item from the selectbox. I also need to be able to hide a div until a use selects an item from the box.

 

<script language="javascript">
function changeBack(form){
  for (var i = 0; i < form.folder.options.length; i++) {
    if (form.folder.options[i].selected){
      alert("Photo will be saved too " + form.folder.options[i].text + ".");
    }
  }
}
</script>

    if (form.folder.options[i].selected){
      alert("Photo will be saved too " + form.folder.options[i].text + ".");
      document.getElementById('some_div').style.display = 'block';
    }
  }
}
</script>
<div id="some_div" style="display:none;">Here is the contents</div>

i have another question related to this. my select boxes are on another page via iframe and the div i want to show/hide is on the main page. is it possible to use contentWindow to access the ID on the other page?

[rhodesa]

is the main page and the page in iframe on the same domain?

[acctman]

is the main page and the page in iframe on the same domain?

 

yes the main page has the iframe and page top has the selectbox

[rhodesa]

no no...same DOMAIN...are they from the same hostname? are they both at http://www.somesite.com for instance? the answer is yes in that case. if not, and one page is from some other host, then no, you can't (it's a security thing)

yes both are on the same domain and directory

[rhodesa]

ok, good...in that case it would be:

parent.document.getElementById('some_div').style.display = 'block';

that worked perfectly thank you so much.
