Check you have declare and change the type="submit" instead type="button" you cant use the word msg as variable and cant pass the js value in ajax and check un variable.

<form>
   <input type="text" id="txtmsg" name="txtmsg" size="25"> <input type="submit" value="send" onclick="sndmsg()">
</form>


<script>
    function sndmsg() {
        msg1=$("#txtmsg").val();
        $.post("insert.php",{u:un,m:msg},function(){ });
        document.getElementById('txtmsg').value=""; 
    }
    $.ajax({
        type: "POST",
        url: "insert.php",
        data: { u: un,m:msg1},
    });
</script>

What is un in jscript.js. Maybe, that parameter is unknown.

$.post("insert.php",{u:un,m:msg},function(){ });

You should declare un and msg variables;

var un, msg;
