Javascript to resize textarea

I am looking for a javascript that can resize a text area based on the size of a window.

Specifically, the textarea is inside a table like this:

<table width="100%">
  <tr>
    <td>stuff</td>
    <td>more stuff</td>
    <td><textarea name="mytextarea" cols="40" rows="5"></textarea></td>
  <tr>
</table>

Right now, the "cols" parameter is hard coded to 40.  I would like to dynamically change that to be relative to the size of the window.  If anyone can share a javascript that does something like that, I would appreciate it.

quiTech,

Use an id in the textarea tag to make this easier.  You can change the column setting with the following assuming the id in textarea is also mytextarea.

document.getElementById("mytextarea").cols = 30;

Let me know if you have any questions or need more information.

You need no JavaScript for that; all you need is CSS style:


<table width="100%">
  <tr>
    <td>stuff</td>
    <td>more stuff</td>
    <td><textarea name="mytextarea" style="width:100%; height:200px;"></textarea></td>
  <tr>
</table>

Thanks to both of you!  Zvonko's solution is easier to implement and doesn't involve having to make calculations as to how big the area should be.  But b0lsc0tt is what I asked for (not knowing a javascript wasn't needed).  I'll split the points!  Thanks again!

I'm glad that I could be one of those that helped.  I'm glad that Zvonko posted and you split; his post is good and correct.  I figured it needed to be more dynamic (i.e. calculated) so automatically switched to JavaScript but I would choose CSS over JavaScript if JavaScript wasn't required.

Thank you for the grade, the points and the fun question.
