(Javascript) I cannot access an element from an iFrame that is on the main page.

[msimmons]

I am running some code in an iframe that alters elements on the page that the iframe is on. I can alter one (a div) but cannot alter the other (an imput). Any ideas?

<script language="javascript">
if (window.parent.reservationReservationID){
alert('found it');
}else{
alert('did not find it');
}

with (window.parent){

reservationfind.style.background='yellow';
}
</script>

as you can tell from the above code I am just testing to see if the imput is there (it is... I have triple checked). I keep getting the alert 'did not find it'. I am able to change the color of the other item though.

Is your input in a form? if yes, then your reference is invalid. If no, then your reference is valid for IE only. Instead, use one of these:

parent.getElementById('reservationReservationID')

or

parent.formName.reservationReservationID

or

parent.formName.elements['reservationReservationID']

I hadden't received the email notification yet of your post but was comming back to reply that I found it :)

You are correct, it is in a form and i used:
window.parent.formName.reservationReservationID

I tried:
parent.getElementById('reservationReservationID')

before posting but received:
Object doesn't support property or method.

Thanks,

Sorry, should be

parent.document.getElementById('reservationReservationID')

Cool it worked :)
That is more up to standards right?

Yes, definitely, although referencing an object via it's form is perfectly valid. I prefer to use the elements collection when doing so.

Same here... even though I perfer to use IE and develop under it I try to stay as close to the standards as I can.
Thanks again,
