I have a textarea, On every Enter key pressed in textarea I want new line to be started with a bullet say (*). How to go about it ?

No jQuery please.

I can observe for the Enter key , after that !? Should I have to get the whole value of textarea and append * to it and again fill the textarea ?

You could do something like this:

<body>



<textarea id=txtArea onkeypress=onTestChange();></textarea>



<script>

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;

    }

}

</script>



</body>

Although the new line character feed from pressing enter will still be there, but its a start to getting what you want.
