问题描述
我有一个代码在google map api中从数组中绘制多边形,但它不起作用
I have a code that draw polygon from array in google map api but it does not work
<!DOCTYPE html>
<html>
<head>
<script src="https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false" type="text/javascript"></script>
<script src="http://code.jquery.com/jquery-latest.min.js" type="text/javascript"></script>
<script>
function drawPoly(multipolygonWKT) {
var polylines = [];
var toReturn = [];
var formattedValues = multipolygonWKT.replace("))", "");
formattedValues = formattedValues.replace("((", "");
var linesCoords = formattedValues.split("),(");
for (i = 0; i < linesCoords.length; i++) {
polylines[i] = [];
var singleLine = linesCoords[i].split(",");
for (j = 0; j < singleLine.length; j++) {
var coordinates = singleLine[j].split(" ");
var latlng = new google.maps.LatLng(parseFloat(coordinates[1]), parseFloat(coordinates[0]));
polylines[i].push(latlng);
}
}
//by now you should have the polylines array filled with arrays that hold the coordinates of the polylines of the multipolyline
//lets loop thru this array
for (k = 0; k < polylines.length; k++) {
var line = polylines[k];
if (k > -1) {
toReturn.push(
new google.maps.Polygon({
paths: line,
strokeColor: 'red',
strokeOpacity: 1,
strokeWeight: 2,
zIndex: 1
})
);
}
}
return toReturn;
}
$(document).ready(function () {
var map = new google.maps.Map(document.getElementById("map"), {
center: new google.maps.LatLng(24.886436490787712, 70.2685546875),
zoom: 5,
mapTypeId: google.maps.MapTypeId.ROADMAP
});
debugger;
var mps = ["MULTIPOLYGON(((25 80.1,18.4 66.1,32.3 64.7,25.7 80.1)),(25.1 80.5,18.8 66.1,32.9 64.2,25.1 80.5))"];
for (i in mps) {
var lines = drawPoly(mps[i].replace("MULTIPOLYGON", ""));
for (k = 0; k < lines.length; k++) {
lines[k].setMap(map);
google.maps.event.addListener(lines[k], 'mouseover', function () {
this.setOptions({ fillColor: "red" });
});
google.maps.event.addListener(lines[k], 'mouseout', function () {
this.setOptions({ fillColor: "white" });
});
}
lines.length = 0;
}
});
</script>

<body>
<div style="height:1000px;width:1200px;" id="map"></div>

这段代码在这里用这个纬度这个
但是不能工作在我的纬度
this code work here by this lat lon this but not work whis my lat lon
推荐答案
您在WKT表示中反转了经度和纬度。这应该是经度纬度:
You have the latitude and longitude reversed in the WKT representation. That should be "Longitude Latitude":
更改此:
Change this:
var mps = ["MULTIPOLYGON(((25 80.1,18.4 66.1,32.3 64.7,25.7 80.1)),(25.1 80.5,18.8 66.1,32.9 64.2,25.1 80.5))"];
收件人:
var mps = ["MULTIPOLYGON(((80.1 25,66.1 18.4,64.7 32.3,80.1 25.7),(80.5 25.1,66.1 18.8,64.2 32.9,80.5 25.1)))"];
