You could do something like this    lt body gt    lt textarea id  txtArea  onkeypress  onTestChange     gt  lt  textarea gt    lt script gt  function onTestChange         var key   window event keyCode          If the user has pressed enter     if  key     13            document getElementById  txtArea   value   document getElementById  txtArea   value     n            return false            else           return true           lt  script gt    lt  body gt    Although the new line character feed from pressing enter will still be there  but its a start to getting what you want

You need to consider the case where the user presses enter in the middle of the text  not just at the end  I d suggest detecting the enter key in the keyup event  as suggested  and use a regular expression to ensure the value is as you require    lt textarea id  t  rows  4  cols  80  gt  lt  textarea gt   lt script type  text javascript  gt      function formatTextArea textArea            textArea value   textArea value replace      r n  n          g    1  2               window onload   function             var textArea   document getElementById  t            textArea onkeyup   function evt                evt   evt    window event               if  evt keyCode    13                    formatTextArea this                                    lt  script gt
