You can't get the line value because it does not exist in the object.  The value is a single string.

As for limiting width you can use cols="100" to limit the visible width, but if the user continues to type, it will just wrap to the next line.  

You could use a key event to count the number of key strokes, but it would take a lot of JavaScript to filter the input for things like backspace the cursor keys, enter, tab, etc...

You could get the x,y co-ordinates of the cursor within the window then use some scripting to work out the position within the textarea, if it is absolutely positioned, but thea would not give you the row column position reliably because the user setting will make calculations based on font size impossible.

What is it you are trying to accomplish?  Maybe there is another way.

In one of my applications the user can add comments to a certain action, and then the comment is saved to a database.

The comment can be as long as the user types.

The thing is that the the comment database field can only contain 80 characters.
I can add as many rows as needed for the comment.

in other words I need to take apart the comment and save line by line in the database.

for example:


Action CommentLine CommentText
 1      1           abcd..... (up to 80 characters)
 1      2           efgh..... (up to 80 characters)
 1      3           ijkl..... (up to 80 characters)

 2      1           abcd..... (up to 80 characters)
 2      2           efgh..... (up to 80 characters)
 2      3           ijkl..... (up to 80 characters)

It would be easier to do it with server side script I think.  If you are updating a database, then it might be easier to break it up in the script you are using.

Client side, you could count the characters and break every 80 characters and put the pieces in a serious of hidden text boxes, but you would still have to make changes on the server side to process the additional fields.

Thae fact that no has commented for two weeks should tell you that there is nothing.  You are going to have to process it server side of take another approach.
