Question text area and hyperlinking
Hi everyone,

Is it possible to make tha contents of a text area hyperlinked so clicking one line will repopulate the text area with fresh contents based on link?

eg

Display all directories in the drive in the text area. clicking on a directory name should repopulate textbox with the clicked directory contents



Thanks in Advance.

Aparna

To my knowledge, this is not possible. You could achieve a similar effect by using a DIV whose style makes it look like a textarea and whose overflow property is set to "scroll." This would allow you to have clickable links while emulating the appearance of a textarea.

i am using a list area to display the contents.the directory names there are hyperlinks .My problem now is clicking the links just refreshes the page instead of displaying the clicked directory contents.
HAPPY NEW YEAR
Thanks in advance.

It's kind of hard to decipher exactly what your code's doing, but my guess is that when you have a directory selected, validation() is returning true and the page is submitting itself because you gave it no action.

Maybe try moving the last line of validation() up above the return true statement. The script is never getting to that line because it returns, and perhaps moving it up will set a variable that your PHP uses to list the selected directory's contents.

Are you referring to the width of the SELECT box? If so, it changes width depending on the content inside it. It is possible to overide the width by using CSS.

e.g.
Code:
<select style="width:200px;">
  <option>foobar</option>
</select>

Looks like it's working alright to me. As far as the width, stumpy's dead on.

Oh yeah - the directory browsing stuff seems to work fine for me too.

I get a page full of PHP errors when I initially load the page though.
