javascript - 如何在div中显示函数返回的内容？

现在它处于警报状态，但是如果我想在div中添加包含的结果，它就不起作用了。任何人都可以向我解释我该怎么做？

<html>
</head>
<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false&libraries=geometry"></script>
<script>
var distance;
var p1 = new google.maps.LatLng(45.463688, 9.18814);
var p2 = new google.maps.LatLng(46.0438317, 9.75936230000002);

//document.getElementById("distance").innerHTML = calcDistance(p1, p2);
alert(calcDistance(p1, p2));

//calculates distance between two points in km's
function calcDistance(p1, p2){
  return (google.maps.geometry.spherical.computeDistanceBetween(p1, p2) / 1000).toFixed(2);
}
</script>
</head>
    </body>
        <div id="distance"></div>
    </body>
</html>
