# 1 Re: help with iframes...
If you are trying to call between frames, you need to reference the parent first.
parent.document.getElementById('iframe_id')
# 2 Re: help with iframes...
ya after i get the handle of the frame with
var hand = mywind.document.getElementById('frame_id');
how do i use hand to write to the frame using "document.write" ?
shud i say hand.write() ? that doesnt work...
shud i say hand.document.write() ? that too doesnt work...
shud i say var tmp = hand.contentDocument;
tmp.document.write() ?? this too doesnt work i guess...
plz lemme kno wat may i do to write to the frame ?
# 3 Re: help with iframes...
hand.document.write() ? that too doesnt work...
I will work if you are truly grabbing the window. If you aren't grabbing, then of course it won't work.
ya after i get the handle of the frame with
var hand = mywind.document.getElementById('frame_id');
You are replacing "frame_id" with the actual frame id aren't you? Also, as I stated before, if you are calling an iframe from another iframe, you need to use the parent.
To test to see if you actually grabbed the window, alert its innerHTML. If the source is alerted, then you have it.
# 4 Re: help with iframes...
I cant alert the innerHTML in XUL..
I am sure I am grabbing the window...
Still i get the error 'hand.document' has no properties...
# 5 Re: help with iframes...

If you aren't able to read anything from the document, then you aren't grabbing the window.
Can you post your two frame source codes please? That will help shed some light on this. Please remember to use [code] tags.

script code
function openPopupMenu(){
mywind=
window.open( "chrome://window/content/frame.xul", "Message", "chrome,scrollbars=1,height=300,width=800");
mywind.onload = openmenu;
}
function openmenu(){
var hand = mywind.document.getElementById('m');
alert(hand);
hand.document.write('india');
}
# 7 Re: help with iframes...
Try the following...
function openPopupMenu(){
mywind = window.open( "chrome://window/content/frame.xul", "Message", "chrome,scrollbars=1,height=300,width=800");
mywind.onload = function(){
mywind.document.write('india'); // maybe try this instead of mywind
};
}
# 8 Re: help with iframes...
that said 'mywind.document.write' is not a function...
then i tried...
function openPopupMenu(){
mywind = window.open( "chrome://window/content/frame.xul", "Message", "chrome,scrollbars=1,height=300,width=800");
mywind.document.open();
mywind.onload = function(){
mywind.document.write('india'); // maybe try this instead of mywind
};
}
this gave me no error... but i dint show me anything on the window...
i cudnt understand why the code u gave me will write to the 'iframe' instead of the document... my intention is to write to the particular iframe
# 9 Re: help with iframes...
my intention is to write to the particular iframe
Oops. I forgot that part.
function openPopupMenu(){
mywind = window.open( "chrome://window/content/frame.xul", "Message", "chrome,scrollbars=1,height=300,width=800");
mywind.onload = function(){
var theFrame = mywind.document.getElementById('m');
theFrame.document.write('india'); // maybe try this instead of mywind
};
}
However, I find it odd that it is not recognizing the write() function. If the above code does not work with this or mywind, you should then research if write() works with Thunderbird.
# 10 Re: help with iframes...
Now it says the 'theFrame.document' has no props...
I m sure write() works with thunderbird cuz i have used it...
i have also tried this...
var testFrame = mywind.document.getElementById('m');
var doc = testFrame.contentDocument;
if (doc == undefined || doc == null){
doc = testFrame.contentWindow.document;
}
doc.open();
doc.write('india');
doc.close();
# 11 Re: help with iframes...
Try dropping the id and using a name.
function openPopupMenu(){
mywind = window.open( "chrome://window/content/frame.xul", "Message", "chrome,scrollbars=1,height=300,width=800");
mywind.onload = function(){
mywind.document.FRAMENAME.document.write('india'); // maybe try this instead of mywind
};
}
# 12 Re: help with iframes...
but that said 'mywind.document.M' has no props
i tried this :
var hand = mywind.document.getElementById('m');
var d = hand.contentDocument;
if(d==null || d==undefined)
alert('no');
else
alert('yes');
var l =d.getElementsByTagName('hbox');
alert(l.length);
//d.write('india');
this returned 2... which was right for i had 2 dummy hboxes in the mainframe.xul...
but when i said d.write() it says 'd.write()' is not a function...
is there no solution for this :( :(
# 13 Re: help with iframes...
atlast i could do it !!!!!!!!!
i just removed the src attribute from the iframe tag...
now i cud write to the iframe...
the small change i made was :
<iframe id='m'>
</iframe>
but what in case the src tag is mandatory... like it has it's own design ?
ne ways for now it works...
thank you for all the help...
# 14 Re: help with iframes...
The iframe has no required attributes. They are all optional.
