php, iframe and javascript help please

Hi folks,

Im currently coding a website, and doing the cms part at the moment.

Im having problems with adding content into my textarea input.

What im trying to do is when i click on a link, it adds the text into the textarea. I have it working fine when the link is in the same page as the textarea, but i was wondering how i refer to the textarea that is in a different page, for example.

document 1 has a textarea in it.
document 2 has a load of links in it.

When i click a link in document 2, i want the text to be added to the textarea in document 1.

Im using an iframe in document 1 that displays all the links in document 2.

The code i am using to add text to the textarea is as follows.

PHP:

<html>
<head>
<script language="javascript">
function addtext(newtext)
{
	document.add.content.value=document.add.content.value+=newtext;
}
</script>
</head>
<body>
<?php

$path="./images/work";
$images=opendir($path);
while(($file=readdir($images)) !==false)
{
	if($file=="." || $file=="..")
	{
	}
	else
	{
	echo "<a href='$path/$file' target='_blank'><img src='$path/$file' width='50'/></a>";
	echo "<a href=javascript:addtext('picture');>$file</a><br/>";
	}
}
closedir($images);
?>
</body>
</html>

What im trying to find out is how to reference a different document, where i use it in the javascript.

Does anyone know, if so, could you please enlighten me.

Thank you,

Edward

the target attribute?

Code:

<iframe name="blah"></iframe>
<a href="javascript:addText('text')" target="blah">Link</a>

untested and uncertain.. I don't use iFrames.

An I'm Feeling Lucky google for "Javascript iFrame" produced this:

THanks for that, got it working now.

Was just parent.document.blah etc

Im stuck again now though.

My javascript decides not to work when i try to pass a peice of code as text through it.

Here's my code that im using.

PHP:

echo "<a href=javascript:addtext('<img src=edward.jpg>');>file</a><br/>";

It works fine when i put in

PHP:

echo "<a href=javascript:addtext('edward');>file</a><br/>";

So im guessing its to do with the text formatting that i am using.

Im wanting to put in the addtext parameter a peice of code like <img src="edward.jpg" size="200" class="imgFrame"/>

How do i need to set it out to do that? I think its finding a speech mark or something somewhere that is cutting the javascript apart.

When i use that top peice of code, the page displays

');?>file

and thats it. Can someone please explain where I'm going wrong?

Cheers again

Edward

I'm not sure exactly what going wrong but trying this might help:

Code:

echo '<a href="javascript:addtext(\'<img src=edward.jpg />\')">file</a><br/>';

If that doesn't work I guess you could create an addimage function, which takes the src as an argument and adds in the HTML itself.
