So what's going on with printing an iFrame - MSDN does not mention this onject even having this method - which I am incredulous at.

I want to be able to load text documents for printing you see - but if I can't print them, that's no good at all.

I tried onLoad="this.print()" which returned, 'object does not support this property or method' - indicating to me, I think; that it is not possible to do so, which I find a little annoying. Maybe in the future! ;)

bangers,

this in your example above is referring to the window object. now if you want to do it like that, try something like:

function printIt()
{
if(this.document.readyState=="complete")
{
this.print()
}
}

iframeobj.onreadystatechange = printIt

when you assign an event handler through script, this refers to the object the event is for... jaredn@subdimension.com -

Oh sorry - I meant I used

<iframe onLoad=&quot;this.print()&quot;...>

Does this change what you mean?

bangers,

{
if(this.document.readyState==&quot;complete&quot;)

oops, messed up the TGML last time... what i'm saying is the this keyword, in event handlers designated with the following syntax:

<body onload=&quot;x=this.something&quot;>

is referring to the property something of window, while when you use the following syntax:

function someFunction()
{
x=this.something
}

document.body.onload=someFunction

this is referring to property something of document.body

if you are still confused, or want to know more about why this is true, let me know

I totally agree with what you're saying - but I am sure I am not referring to the outside window..
if
<iframe onLoad=&quot;this.print()&quot;...> is calling the window's print function, then why didn't it print?

The thing is - I called it from inside the iframe object, to me meaning that this refers to the iframe.

As a test - I called:
<iframe onLoad=&quot;alert(this.name)&quot; name='Frame_1'...>

and this gave me &quot;Frame_1&quot;, not the main window name? Are we at crossed purposes here? :)
