Mailto using Javascript? [duplicate]

Question

I'm new to javascript and the following code isn't working:

<script>
function sendMail()
{
    var yourMessage = document.getElementById("message").value
    var subject = document.getElementById("selectList").value
    var mail="mailto:[email protected]?subject="+subject+"&body="+yourMessage;

    window = window.open(mail, 'emailWindow')
}
</script>

I just want a mail client window to open with the subject and body already done.

Help?

EDIT:

I've also tried this:

<script>
function sendMail()
{
    var yourMessage = document.getElementById("message").value
    var subject = document.getElementById("selectList").value
    var mail="mailto:[email protected]?subject="+subject+"&body="+yourMessage;

    $(this).attr('href', mail);
}
</script>

Ive got that now, still not working.

Answer 1

Your code should look like this instead:

<script>
function sendMail()
{
    var yourMessage = document.getElementById("message").value;
    var subject = document.getElementById("selectList").value;
    document.location.href = "mailto:[email protected]?subject="
        + encodeURIComponent(subject)
        + "&body=" + encodeURIComponent(yourMessage);
}
</script>
