构建多边形时遇到问题。错误消息显示如下:
构造函数参数 0 的值无效:(49.27862248020283, -122.79301448410035),(49.277964542440955, -122.79370112960816),(49.278524490028595, -122.7950207764)
它一定是一些简单得可笑的东西,但我就是看不到。您的任何提示都是有用的。
我基本上是在模态窗口(带有检票口)上的 iframe 内绘制地图。一切都很好,但是当我尝试显示一个多边形时(这些点是从数据库加载并由 web 服务发送的),我收到了错误消息。
iframe 代码:(仅相关)
/**
* Draws the polygon.
*/
function drawPolygon() {
if (order >= 3) {
deleteMarkers();
// Construct the polygon
// Note that we don't specify an array or arrays, but instead just
// a simple array of LatLngs in the paths property
polygonObject = new google.maps.Polygon({
paths: polygonCoords,
strokeColor: "#FF0000",
strokeOpacity: 0.8,
strokeWeight: 2,
fillColor: "#FF0000",
fillOpacity: 0.35
});
polygonObject.setMap(map);
isPolygonDrawed = true;
//After we create the polygon send the points to wicket
parent.sendPoints();
//Change the message on the top label
controlText.style.color = '#ADAAAA';
controlText.innerHTML = polygonCreated;
//With this we make sure no other markers are created after the polygon is drawed.
//Is assigned (order - 1) because when this code is called the order has already been added 1.
MAX_POLYGON_VERTEX = order - 1;
//Disable the create polygon button.
enable = false;
createControlText.style.color = '#ADAAAA';
}
else alert(alertMessage);
}
现在父级(模态窗口)上的代码
/**
* Show the polygon on map.
*/
function showPolygon(zoneId) {
var url = applicationRootUrl + 'zonePointsOnMap?zoneId=' + zoneId;
$.getJSON(url, function(data) {
if(data.length == 0) {
return false;
}
frames['zoneMapIFrame'].order = parseInt(data.length);
alert(data.length);
$.each(data, function(i, item) {
if(item != null) {
if(item.latitude != null && item.longitude != null) {
var lat = parseFloat(item.latitude);
var lng = parseFloat(item.longitude);
var latlng = new google.maps.LatLng(lat, lng);
var pointOrder = item.order;
frames['zoneMapIFrame'].polygonCoords[pointOrder] = latlng;
alert(item.order + " point " + latlng);
frames['zoneMapIFrame'].bounds.extend(latlng);
}
}
});
});
setTimeout("frames['zoneMapIFrame'].drawPolygon()", 200);
setTimeout("frames['zoneMapIFrame'].fitMapZoomPolygon()", 300);
}
我可以看到这些点已加载好警报,但我不断收到错误消息。
帮我!
