我想在谷歌地图上显示一个位置,但我不知道我的错在哪里。没有显示任何东西:
<div id="map-canvas" style="width:100%; height:300px;">
</div>
.
.
.
<script src="https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false"></script>
<script>
// Google map
if ($('#map-canvas').length) {
var
GOOGLE_MAP_LAT = 40.7564971,
GOOGLE_MAP_LNG = -73.9743277;
var map,
service;
jQuery(function($) {
$(document).ready(function() {
var latlng = new google.maps.LatLng(GOOGLE_MAP_LAT, GOOGLE_MAP_LNG);
var myOptions = {
zoom: 14,
center: latlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById("map-canvas"), myOptions);
var marker = new google.maps.Marker({
position: latlng,
map: map
});
marker.setMap(map);
$('a[href="#google-map-tab"]').on('shown.bs.tab', function(e) {
google.maps.event.trigger(map, 'resize');
map.setCenter(latlng);
});
});
});
}
</script>
</body>

我认为你需要包含jquery库,因为你使用的是$(document).ready(function()。 我已经通过添加jquery库更新了您的代码。请尝试下面的代码,希望它能运作。
<div id="map-canvas" style="width:100%; height:300px;">
</div>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.0/jquery.min.js"></script>
<script src="https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false"></script>
<script>
// Google map
if ($('#map-canvas').length) {
var
GOOGLE_MAP_LAT = 40.7564971,
GOOGLE_MAP_LNG = -73.9743277;
var map,
service;
jQuery(function($) {
$(document).ready(function() {
var latlng = new google.maps.LatLng(GOOGLE_MAP_LAT, GOOGLE_MAP_LNG);
var myOptions = {
zoom: 14,
center: latlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById("map-canvas"), myOptions);
var marker = new google.maps.Marker({
position: latlng,
map: map
});
marker.setMap(map);
$('a[href="#google-map-tab"]').on('shown.bs.tab', function(e) {
google.maps.event.trigger(map, 'resize');
map.setCenter(latlng);
});
});
});
}
</script>
