Updating multiple iframes and passing variables

Hi there,

I'm building a page in PHP which displays a calendar. Each day on the
calendar is a hyperlink, which should update two inline frames on that
very same page.

When the user clicks on one of the hyperlinks (that represents a day)
a variable should be passed to both of the iframes, like this :

<a href="Grapic_day.php?day=31" target="Graphic_day">31</a>
<a href="List_day.php?day=31" target="List_day">31</a>

though, now I've made TWO links, and I would like BOTH iframes updated
trough ONE link. Is there any way to do this, using some kind of
javascript, so that both destination urls will get the correct
variable, WHITHOUT refreshing the parent window?!?

I didn't get much further then :

<a href="#" onclick="document.Graphic_day.src="Graphic_day.php ?day=31";
document.List_.src="List_day.php?day=31";">31</a>

But that didn't work. Forgive me if this looks a little bit stupid,
but I'm no javascript expert...

can anyone help me on this?!?

Well, to give an answer to my own question... :-S

I've been searching for about a day right now, and I've come up with
this solution, which I found somewhere on this discussion board.

In the header of my document I've put this script :

<SCRIPT LANGUAGE="javascript">
function SwitchFrames(url1,url2,url3) {
parent.Graphic_day.location.href = url1
parent.List_dayly_views.location.href = url2
parent.List_dayly_hits.location.href = url3
}
</SCRIPT>

And in the body, where the links of each day appear I've used this
link, which can perfectly be generated 31 times trough a PHP script,
while passing on a different set of variables each time :

<a href="javascript:SwitchFrames('Graphic_day.php?day =31','List_dayly_views.php?day=31','List_dayly_hit s.php?day=31');">

Worked for me! Hope it might be usefull for someone else too
someday... ;o)

Greetz!
