<!DOCTYPE html>

<script type="text/javascript" language="javascript">
function my_func(event){
$("#log1").html("mouse is down");
var x = $(this);
//some code
$(document).ready(function(){
x.on("mousemove", function(){
$("#log1").html("x:"+event.pageX+" y:"+event.pageY);
});
});
}
$(document).ready(function(){
$("button").on("mousedown",my_func); //it needs to be a named function because I will call it multiple times
});

<button >TEST</button>
