我目前正在尝试将地理位置功能添加到以下代码中:
<script type="text/javascript" src="http://maps.googleapis.com/maps/api/js?sensor=false"></script>
<script type="text/javascript">
var marker;
var infowindow;
function initialize() {
var latlng = new google.maps.LatLng(51.507059, -0.122631);
var options = {
zoom: 14,
center: latlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
var map = new google.maps.Map(document.getElementById("map-canvas"), options);
var html = "<table/>" +
"<tr><td>Name:</td><td><input id='name' type='text'/></td></tr>" +
"<tr><td><br/>Description:</td><td><input id='description' type='text'/></td></tr>" +
"<tr><td/><td><br/><center><input onclick='saveData()' type='button' value='Save & Close'/></center></td></tr>";
infowindow = new google.maps.InfoWindow({
content: html
});
google.maps.event.addListener(map, "click", function(event) {
marker = new google.maps.Marker({
position: event.latLng,
map: map
});
google.maps.event.addListener(marker, "click", function() {
infowindow.open(map, marker);
});
});
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
地理位置代码:
// HTML5 geolocation
if(navigator.geolocation) {
navigator.geolocation.getCurrentPosition(function(position) {
var pos = new google.maps.LatLng(position.coords.latitude,
position.coords.longitude);
var infowindow = new google.maps.InfoWindow({
map: map,
position: pos,
content: 'Location found using HTML5.'
});
map.setCenter(pos);
}, function() {
handleNoGeolocation(true);
});
} else {
// Browser doesn't support Geolocation
handleNoGeolocation(false);
}
}
function handleNoGeolocation(errorFlag) {
if (errorFlag) {
var content = 'Error: Locations services failed.';
} else {
var content = 'Error: Your browser doesn\'t support geolocation.';
}
var options = {
map: map,
position: new google.maps.LatLng(51.507059, -0.122631),
content: content
};
var infowindow = new google.maps.InfoWindow(options);
map.setCenter(options.position);
}
但是,当我尝试合并初始化函数时,我收到错误'无法读取属性'_ e3 '未定义。如果我将函数分开,程序就会忽略地理位置代码。所以,我被困住了,并希望有人可以帮助我。万分感谢!
注意:我在https://developers.google.com/maps/尝试了所有相关内容,并检查了本网站上所有非常相似的问题 - 这不是重复的帖子。另外,请忽略我在JavaScript中使用HTML字符代码 - 这是在HTML(webdata)内部的JavaScript(代码)内部获取HTML(infowindow)的唯一方法。
