addEventLinstener监听Marker之后重复

Question

百度地图用addEventLinstener监听几个marker之后，再把几个marker连接起来结果就报错了

<script Language="JavaScript" type="text/javascript">
var id = <?php echo json_encode($id);?>;
var time = <?php echo json_encode($time);?>;
var height = <?php echo json_encode($height);?>;

var date = <?php echo json_encode($date);?>;
var speed = <?php echo json_encode($speed);?>;
var rownum = <?php echo json_encode($rownum);?>;

var Point = new Array();

for(var i=0;i<rownum;i++) {
    Point.push(new BMap.Point(longitude[i], latitude[i]));
}

function transcoord() {
    translateCallback = function (data) {
        var transPoint = new Array();
        var Marker = new Array();
        if (data.status === 0) {
            for(var i=0;i<rownum;i++) {
                transPoint[i]=data.points[i];
                Marker[i]=new BMap.Marker(data.points[i]);
                map.addOverlay(Marker[i]);

                function Listener() {
                    //var thePoint = transPoint[i];
                    //var theMarker = Marker[i];
                    var theTime = "00:00:00";
                    Marker[i].addEventListener("click",function(){
                        showInfo(this,theTime);
                    });
                }
                Listener();
            }

            function showInfo(thisMaker,time){
                var sContent =

                    +"</ul>";
                var infoWindow = new BMap.InfoWindow(sContent);  // 创建信息窗口对象
                thisMaker.openInfoWindow(infoWindow);   //图片加载完毕重绘infowindow
            }

            function drawline() {
                var polyline = new Array();
                for(var k=0;k<rownum;k++){
                    polyline[k] = new BMap.Polyline([transPoint[k],transPoint[k+1]]
                        , { strokeColor:"green",//设置颜色
                            strokeWeight:3, //宽度
                            strokeOpacity:0});//透明度
                    map.addOverlay(polyline[k]);
                }
            }

            drawline();

        }else{
            alert(data.status);
        }
    }

    var convertor = new BMap.Convertor();
    convertor.translate(Point, 1, 5, translateCallback);

}

transcoord();

</script>

运行之后一开始是这样的

然后点击marker之后，，不会有点击事件，而且又画了一段一样的轨迹出来。。。

浏览器疯狂报错

求解

但是如果在drawline那里不用循环只画其中一段轨迹的话，不会报错，点击事件也是正常的
