How to remove extra space inside textarea

I know its late but may help others.

use this when document indentation is required.

$('document').ready(function()
{
    $('textarea').each(function(){
            $(this).val($(this).val().trim());
        }
    );
});

Its because your php tag is on a newline. It is reading in the whitespace from where <textarea> ends until php tag opens. Put this all on one line to fix.

Put this all on one line for fix this issue.Make your code like this.

<textarea style="margin-left:90px";name="history"cols="80"label="notes"rows="4"wrap="virtual"><?php echo $my_class->history;?></textarea>
