Openlayer在Openlayer绘制功能中添加点
我正在尝试使用 openlayer（多边形）的绘制功能。最终用户可以绘制多边形。但我想通过java脚本绘制多边形。我尝试使用openlayer的insertXY和insertDeltaXY函数，但出现js错误“对象不支持属性或方法'insertXY'”。
以下是我的代码块。
var draw = new OpenLayers.Control.DrawFeature(
vectorLayer,
OpenLayers.Handler.Polygon }
);
map.addControl(draw);
draw.activate();
//Listen for sketch events on the layer
draw.layer.events.on({
featureadded: that.PolygonAdded
});
//Draw polygon if provided from codebehind
//Insert a point in the current sketch given x & y coordinates
handler.insertXY(cords[0], cords[1]);
//Insert a point given offsets from the previously inserted point.
handler.insertDeltaXY(cords[2], cords[3]);
handler.insertDeltaXY(cords[4], cords[5]);
.....
非常感谢任何帮助。
I am trying to use draw feature of openlayer (polygon). It is possible for the end user to draw a polygon. But I want to draw the polygon through java script. I am trying to use insertXY and insertDeltaXY functions of openlayer, but there comes a js error "Object doesn't support property or method 'insertXY'".
Follow is my chunk of code.
var draw = new OpenLayers.Control.DrawFeature(
vectorLayer,
OpenLayers.Handler.Polygon }
);
map.addControl(draw);
draw.activate();
//Listen for sketch events on the layer
draw.layer.events.on({
featureadded: that.PolygonAdded
});
//Draw polygon if provided from codebehind
//Insert a point in the current sketch given x & y coordinates
handler.insertXY(cords[0], cords[1]);
//Insert a point given offsets from the previously inserted point.
handler.insertDeltaXY(cords[2], cords[3]);
handler.insertDeltaXY(cords[4], cords[5]);
.....
Any help is highly appreciated.

尝试使用
draw对象插入点。根据 OpenLayers 文档OpenLayers.Control.DrawFeature公开方法insertXY和insertDeltaXY。我不知道你的handler对象是否有这些方法。Try using the
drawobject to insert points. According to the OpenLayers documentationthe
OpenLayers.Control.DrawFeatureexposes the methodsinsertXYandinsertDeltaXY. I don't know if yourhandlerobject has these methods.
