    how to catch keystroke of enter key pressed?

    hi all!

    for example;[enter] represents pressing enter key.
    i am typing "nirmal [enter] singh [enter] B"
    in a text area, so the result in textarea will be in three lines as follows.

    nirmal
    singh
    B

    while i get this data from textarea and save in database, i want to save something representing like enter key pressed or new line along with text. so that i can retrieve the record from database and show it in a same format as

    nirmal
    singh
    B

    how can i do this?

    thanx in advance.

          while passing the value in query string using ajax to save it, the enter character is ignored and saved as a sequence sentence.

              hi ...

              you may use a regEx to prepare the value ... have a look at the following example:

              [CODE=html]<html>
              <head>
              <script type="text/javascript">

              function prepare_value() {
              var value = document.getEle mentById('text' ).value;

              value = value.replace(/(\n|\r\n)/g, '\n');

              alert(value);
              }

              </script>
              </head>
              <body>
              <form name="myform">
              <textarea id="text"></textarea>
              <input type="button" value="prepare" onclick="prepar e_value();">
              </form>
              </body>
              </html>
              [/CODE]
              kind regards

                      You can use a special character and then replace it using your server side script.
                      Mind it your special character should never occur in your Query String.
