我尝试使用 Chrome 和 JSLint 调试此代码 4 天,但没有任何希望。我的代码应该在谷歌地图上显示 2 个区域,由它们分隔RegionID
我的 HTML
<body>
<div id="map_canvas" style="width: 100%; height: 100%;"></div>
<script type="text/javascript"

<script type="text/javascript" src="jquery-1.9.1.min.js"></script>
<script type="text/javascript">
var map;
function initialize() {
var mapOptions = {

zoom: 13,

map = new google.maps.Map(document.getElementById("map_canvas"),
mapOptions);

<script type="text/javascript">

var model = [{"ID":946,"Latitude":10.7654200827348,"Longitude":106.681716282384,"RegionID":80},{"ID":947,"Latitude":10.7563117596896,"Longitude":106.685397072824,"RegionID":80},{"ID":948,"Latitude":10.7537788369752,"Longitude":106.68713674361,"RegionID":80},
{"ID":1271,"Latitude":10.8577143149377,"Longitude":106.657884916756,"RegionID":82},{"ID":1272,"Latitude":10.8576257110992,"Longitude":106.657710314914,"RegionID":82},{"ID":1273,"Latitude":10.8575762617472,"Longitude":106.657500586099,"RegionID":82},{"ID":1274,"Latitude":10.8575794962578,"Longitude":106.657309632748,"RegionID":82},{"ID":1275,"Latitude":10.8576187762307,"Longitude":106.65709567219,"RegionID":82}]
polygon(model);
});
</script>
这是我的polygon
功能
// Take an array of objects that have lat and lon attribute
function polygon(polygonCoords) {
// Initialize
// First dimension
var id = polygonCoords[0].RegionID;
var long;
var lat;
var region = new Array();
for (var i = 0; i < polygonCoords.length; i++) {
if ((id != polygonCoords[i].RegionID) || (i == polygonCoords.length - 1)) {
// Draw polygon
// Set path to a polygon along with polygon's option
var regionPolygon = new google.maps.Polygon({
paths: region,
fillColor: "#0000A0",
editable: false,
});
// Set to map
regionPolygon.setMap(map);
// Reset stuffs
region.length = 0;
id = polygonCoords[i].RegionID;
}
long = polygonCoords[i].Longitude;
lat = polygonCoords[i].Latitude;
region.push(new google.maps.LatLng(lat, long));
}
}
我收到的只是一张没有任何多边形的谷歌地图。我尝试删除 for 循环并按一个变量推送到region
数组,它再次工作。这很荒谬,但这是我在 4 天后发现的。谢谢
