そこで、2 つの Google Maps API チュートリアルを 1 つのマップに結合しようとしています。 このドキュメントとこれ。
以前はサンプル ページに表示されていたマップごとに 2 つのマップが表示されていましたが、今は 1 つのマップが必要です。コンテンツをデータベースに保存しようとする場合を除いて、すべてが機能します。 document.getElementbyId情報ウィンドウのフォームからは何も返されず、座標だけが返されます。
マップが別々の場合は機能しますが、一緒の場合は機能しません。
これは私が組み合わせたコードです：
var customIcons = {
blue: {
icon: 'http://labs.google.com/ridefinder/images/mm_20_blue.png',
shadow: 'http://labs.google.com/ridefinder/images/mm_20_shadow.png'
},
red: {
icon: 'http://labs.google.com/ridefinder/images/mm_20_red.png',
shadow: 'http://labs.google.com/ridefinder/images/mm_20_shadow.png'
}
};
var locationInfowindow;
var locationMarker;
function initialize() {
//get the html from the water
var waterHTML = "Why is water important in your community?" +
"<table>" +
"<tr><td>Name:</td> <td><input type='text' id='watername'/> </td> </tr>" +
"<tr><td>School:</td> <td><input type='text' id='wateraddress'/></td> </tr>" +
"<tr><td>Reason:</td> <td><input type='text' id='waterreason'/> </td></tr>" +
"<tr><td></td><td><input type='button' value='Save & Close' onclick='saveData()'/></td></tr>";
//setup Map
var map = new google.maps.Map(document.getElementById("map"), {
center: new google.maps.LatLng(37.926868, -104.501953),

});
//start the markers from the database
var infoWindow = new google.maps.InfoWindow;
// Change this depending on the name of your PHP file
downloadXMLUrl('mapxml.php', function(data) {
var xml = data.responseXML;
var markers = xml.documentElement.getElementsByTagName("marker");
for (var i = 0; i < markers.length; i++) {

var address = markers[i].getAttribute("school");
var math = markers[i].getAttribute("reason");
var point = new google.maps.LatLng(
parseFloat(markers[i].getAttribute("lat")),
