How to show the external page content using java script ?

[ishare]

Example :
http://www.dwshare.com/imdb/imdb.php?mid=0960144

As you can see from above page, i have the .php pages. There is nothing wrong with that.
I would like to show the above page in my forum.

I have prepared a bbcode called movieinfo for that.
BBCode Content :

<script src="http://www.dwshare.com/imdb/imdb.php?mid={param}"type="text/javascript"></script>

So when a user use the movieinfo bbcode as : [movieinfo]0960144[/movieinfo] he/she will display the above example's content.

Ofcourse i can show this content in iframe. But as i mentioned in my first message, due to all movies do not have same size info, its diffucult to use one size iframe. (Example : width:700px - height:280px) And beside that, it will not fit the style.

When i checked this webpage, i see that its possible to use javascript to display the content of an external page. When i use the movieinfo bbcode with other sites javascript code (at first message), its working.

So i would like to be able to do the same for my own page too. Through google, i learned that with document.write command we can display the info but i couldnt do that.

Thats why i opened this thread if i can find a way to do this kind of simple(!) javascript modify.
