Including javascript (or php) within text area

philhancox · 27-03-08

I currently have a snippet of text displayed on every page that automatically generates a link for them to use:

Code:

<p class="likeit">Link to this page: <textarea id="codearea" name="codearea" rows="6" cols="60">&lt;a href="<?php echo curPageURL();?>" target="_blank"&gt;<?php include ("title.js");?>&lt;/a&gt;</textarea></p>

The page URL is generated through PHP but the title is generated via Javascript. I've now put this text withing a

Code:

<textarea>

but the javascript breaks it, so instead of displaying the title like it should do, it simply displays

Code:

<script language="JavaScript">
document.write (document.title)
</script>

.

Is there a way of including the JS within the textarea so it actually works properly, or put it within a php statement, as the

Code:

<?php echo curPageURL();?>

seems to display correctly.

Cheers

Hi,

You won't be able to include JavaScript into the page within a TEXTAREA tag as all markup between those tags is displayed "asis", as you've discovered...

The first way I can think of to do this is to use JavaScript to update the text, substituting a placeholder (that you write in when generating the page) with document.title.

Try this:

Code:

<p class="likeit">Link to this page: <textarea id="codearea" name="codearea" rows="6" cols="60">&lt;a href="<?php echo curPageURL();?>" target="_blank"&gt;TITLE&lt;/a&gt;</textarea></p>
<script type='text/javascript'>
document.getElementById('codearea').innerHTML = document.getElementById('codearea').innerHTML.replace(/TITLE/,document.title);
</script>

Fingers crossed...!
