碰到一个难题，用循环将点显示在百度地图上，请大神帮看看代码是否有问题

Question

 var map = new BMap.Map("allmap");
    map.centerAndZoom(new BMap.Point(117.124533, 31.863914), 15);

       var polylinePointsArray = [];
       var gridView = document.getElementById("GridView1");
       for (var i = 0; i <gridView.rows(rowIndex).cells.length; i++) {
           for (var j = 0; j < 1; j++) {
               var x = gridView.Rows(i).Cells(j).inner.Text;
                var y = gridView.Rows(i).Cells(j+1).inner.Text;
                polylinePointsArray[i] = new BMap.Point(x, y)              
            }
        }
    polyline = new BMap.Polyline(polylinePointsArray, { strokeColor: "red", strokeWeight: 3, strokeOpacity: 0.5 });
    map.addOverlay(polyline);

    GridView中只有两列横纵坐标，想把坐标存在数组中

Answer 1

rows(rowIndex)改为rows[rowIndex],cells也一样，而且是cells，不是Cells，注意大小写。innerText，不是inner.Text
innerText低版本的浏览器有兼容性问题，改为innerHTML好点
