How to send email with line break?

I'm using JavaMail to send emails. So I've got a textArea where customers can compose their messages and send them to me on button press. During my testing I realize that when I press "Enter"/"Return" key inside my textArea it breaks my text but when I check mail box it just one line text!

How to do it?

Please help me guys!

I' using this code for now and it seems working:

<textarea rows="10" id="Message" onkeypress="BreakLine();"></textarea>

<script type="text/javascript">
function BreakLine() {
    var key = window.event.keyCode;

    // If the user has pressed enter
    if (key == 13) {
    document.getElementById("Message").value = document.getElementById("Message").value + "<br/>";
    }
}
</script>

But when I taped something inside textArea it prints "<br/>" along with the rest text as well but when I receive email its fine I can see breaks in the text like it suppose to be! But how to get rid of "<br/>" inside textArea?

I found this example for outlook (which one I'm using) as well and it uses "\r\n" instead of "<br/>" but it doesn't work for me!

P.S. I know above example will work only for IE but don't worry about it for now...

Try this:

<textarea rows="10" id="Message" onkeypress="BreakLine();"></textarea>
<script type="text/javascript">
    function BreakLine() {
        var key = window.event.keyCode;
        // If the user has pressed enter
        if (key == 13) {
            document.getElementById("Message").value = document.getElementById("Message").value +"\n";
            window.event.preventDefault();
        }
console.log(encodeURIComponent(document.getElementById("Message").value));
    }
</script>

I solve it on my own, so on "Send Email" button click it checks first does text contain /n (break) if "yes" it adds line into array cell (lines). So every line are kept separately. And after that I add every line to hidden textArea value and add <br/> in the end of each line.

Text Areas:

<textarea rows="10" id="Message" name="Message"></textarea>
<textarea id="HiddenMessage" name="HiddenMessage" style="display:none;"></textarea>

Button:

<input type="button" id="SendEmail" value="Send Email" onclick="BreakLine();">

JavaScript:

<script type="text/javascript">
    function BreakLine() {
    var lines = $('#Message').val().split('\n');

    for(var i = 0;i < lines.length;i++){
        document.getElementById("HiddenMessage").value = document.getElementById("HiddenMessage").value + lines[i] + "<br/>";
        }   
    }
</script>

If the message is text/plain, then using \r\n should work. Instead, if the message type is text\html, use then use <p/>.

Did you debug your code and see what string was being passed from the textArea to your code? By the way you can make your javascript cross-browser compatible:

function BreakLine() {
    var key = event.which || event.charCode || event.keyCode;

    // If the user has pressed enter
    if (key == 13) {
    document.getElementById("Message").value = document.getElementById("Message").value + "<br/>";
    }
}

If the above line that gets the key does not work, you could always use jquery's "which" function to get the key code no matter what browser it is.

Edit: You can combine the <br> and the text in your text area and save this value in a hidden field on your page, instead of appending and showing it in your textarea. Then when the message is to be sent, you can get the message text with appended <br>s from this hidden field and send it. This way there will be no annoying <br>s in the text area plus your messages will be multi-line as you want.
