Google マップから XML 形式でデータを取得します。すべての機能が動作していますが、ほとんど問題はありません。最後のデータのみが表示されます。それはなぜですか、どうすれば解決できますか?
これは私のコードです(jsFiddle)
function getline() {
downloadUrl("line.php", function(doc) {
var g = google.maps;
var xmlDoc = xmlParse(doc);
bounds = new google.maps.LatLngBounds();
// ========= Now process the polylines ===========
var lines = xmlDoc.documentElement.getElementsByTagName("line");
// read each line
for (var a = 0; a < lines.length; a++) {
// get any line attributes
var colour = lines[a].getAttribute("colour");
var width = parseFloat(lines[a].getAttribute("width"));
var diameter = lines[a].getAttribute("diameter");
var project = lines[a].getAttribute("projectid");
var contract = lines[a].getAttribute("contract");
var comp = lines[a].getAttribute("complated");
var id = lines[a].getAttribute("id_line");
// read each point on that line
var points = lines[a].getElementsByTagName("point");
var pts = [];
var length = 0;
var point = null;
for (var i = 0; i < points.length; i++) {
pts[i] = new g.LatLng(parseFloat(points[i].getAttribute("lng")),
parseFloat(points[i].getAttribute("lat")));
if (i > 0) {
length += pts[i-1].distanceFrom(pts[i]);
if (isNaN(length)) { alert("["+i+"] length="+length+" segment="+pts[i-1].distanceFrom(pts[i])) };
}
bounds.extend(pts[i]);
point = pts[parseInt(i/2)];
var info = "<b> Contract: </b>" + contract + " <br/> <b>Project: </b>" + project +"<br/> <b>Diameter: </b>" + diameter + " <br/> <b>Complated: </b>" + comp + " <hr><br/><a class=\"inline-link-1\" href=\"#\">Change Data</a> <a class=\"inline-link-1\" href=\"#\">Edit</a> >" + id +"" ;
}
// length *= 0.000621371192; // miles/meter
if (comp < 1) {
colorr = '#FA0505' }
if (comp > 0 && comp < 25 ) {
colorr = '#FFA640' }
if (comp > 24 && comp < 50) {
colorr = '#FFFD91' }
if (comp > 49 && comp < 75) {
colorr = '#E8E400' }
if (comp > 74 && comp < 100) {
colorr = '#BFFFAD' }
if (comp == 100) {
colorr = '#0F8500' }
var polyline = new g.Polyline({
map:map,
path:pts,
strokeColor:colorr,
strokeWeight:width,
clickable: true
});
//createClickablePolyline(polyloine, html, label, point, length);
// map.addOverlay(polyline);
google.maps.event.addListener(polyline,'mouseover', function() {
this.setOptions({strokeColor: '#690469' });
this.setOptions({strokeOpacity: 1.0 });
this.setOptions({strokeWeight: 4 });
});
google.maps.event.addListener(polyline,'mouseout', function() {
this.setOptions({strokeColor: colorr });
this.setOptions({strokeOpacity: 1.0 });
this.setOptions({strokeWeight: 4 });
});
var mpenc = new google.maps.InfoWindow();
google.maps.event.addListener(polyline,'click', function(event) {
mpenc.setContent(info, this);
mpenc.setPosition(event.latLng, this);
mpenc.open(map);
});
}
map.fitBounds(bounds);
});
}
