limit no of char per line
 
hi
i have a text area where i want to limit the number of charactersin each line.
for example if the user enters more than 50 caharacters it should automatically move the cursor to the next line

I do not know if there is a simple way. But at this moment here what you can do.

Write a event handler for onkeyup for your text area and count for every keypress if count exceeds 50 then append '\n'(new line character) by yourself.

thats it.
Your js keyhandler will look somthing like this:-
var count = 0;

function keypress (e) {

     if(count>=50) {

           document.getElementById('textarea_id').value = document.getElementById('textarea_id').value + '\n';

           count = 0;

     } else {

           count++;

     }

}

Of course its working man. I tried it with document.getElementById('id of textarea')

What you want? That a working code is delivered to you so that you can sit back and rest.
