Frame javascript problem!

Copy linkTweet thisAlerts:
Jan 28.2004

Here it is, i have a page that includes 3 frames, 2 vertically and 1 horizontally at the bottom. The two vertical ones will include text boxes. The bottom one will need a javascript function to call up information from the frames above and do mathamatical equations (Such as 65+34 or something).
Does anybody know how to do that?
?

@buntineJan 28.2004 — One method is to use the inbuilt frames array.

[CODE]
var frame_one = top.frames[1];
var frame_two = top.frames[2];

var text_box_one = frame_one.document.getElementsByTagName("input")[0];
var text_box_two = frame_two.document.getElementsByTagName("input")[0];

alert(text_box_one.value + "n" + text_box_two.value);
[/CODE]

Note, you may have to edit the above code. It assumes the first occurance of the <input> element is the textbox.

Also, indexing starts at zero. So frames[1] is actually referring to the second frame on the page.

Regards,

Andrew Buntine.
