我有一个动态页面,根据ID提取不同的位置。我有三个标签,一个用于位置描述,谷歌地图和一个用于街景。一切正常 - 我遇到的问题是,当没有街景时,它会显示一个灰色的框。
我以为我通过使用'getPanoramaByLocation'找到了解决方案,但我似乎无法使其正常工作。这就是我所拥有的:
var WINDOW_HTML = '<div style="width: 200px; overflow: hidden; word-wrap:break-word;"><p><?php echo htmlspecialchars($title); ?><br /><?php echo htmlspecialchars($locationDetails); ?></p></div>';
var map = '';
var myLatlng;
/* Check if Streetview is available */
var latLng = new google.maps.LatLng(<?php echo htmlspecialchars($lat.','.$lon); ?>);
var streetViewCheck = new google.maps.StreetViewService();
streetViewCheck.getPanoramaByLocation(latLng, 50, function(result, status) {
if (status == google.maps.StreetViewStatus.ZERO_RESULTS) {
streetViewAvailable = 0;
} else {
streetViewAvailable = 1;
}
});
function initialize() {
myLatlng = new google.maps.LatLng(<?php echo htmlspecialchars($lat.','.$lon); ?>);
var mapOptions = {
zoom: 13,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
map = new google.maps.Map(document.getElementById('themap'), mapOptions);
/* Street view addition */
if (streetViewAvailable == 1) {
var panoramaOptions = {
position: myLatlng,
pov: {
heading: 34,
pitch: 10
},
visible:true
};
var panorama = new google.maps.StreetViewPanorama(document.getElementById('pano'),panoramaOptions);
map.setStreetView(panorama);
alert('Street View Available');
} else {
/* Hide the street view tab if it isn't available */
$('#svTab').hide();
alert('Street View NOT Available');
}
/* Resize Fix for tabs */
google.maps.event.addListener(map, 'resize', function() {
this.setZoom(13);
this.setCenter(myLatlng);
var infowindow = new google.maps.InfoWindow({
content: WINDOW_HTML
});
var marker = new google.maps.Marker({
position: myLatlng,
map: map
});
google.maps.event.addListener(marker, 'click', function() {
infowindow.open(map,marker);
});
infowindow.open(map,marker);
});
// Tab fix for streetview refresh
$('#svTab').on('shown', function (e) {
$('#pano').show();
panorama.setVisible(true);
});
}
google.maps.event.addDomListener(window, 'load', initialize);
我尝试了很多不同的东西,我似乎得到了不同的结果 - 我似乎有一个设置正在工作,但是当我因某种未知原因刷新页面时,它会说我的'streetViewAvailable'没有被定义(好像它没有通过我的streetViewCheck函数运行)。
答案 0 :(得分:0)
最后设法搞清楚了。我不得不删除“街景视频”&#39;变量,而是将一个函数放在streetviewstatus if语句中。这就是它最终看起来像什么。
var WINDOW_HTML = '<div style="width: 200px; overflow: hidden; word-wrap:break-word;"><p><?php echo htmlspecialchars($title); ?><br /><?php echo htmlspecialchars($locationDetails); ?></p></div>';
var map = '';
var myLatlng;
function initialize() {
myLatlng = new google.maps.LatLng(<?php echo htmlspecialchars($lat.','.$lon); ?>);
var mapOptions = {
zoom: 13,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
map = new google.maps.Map(document.getElementById('themap'), mapOptions);
/* Resize Fix for tabs */
google.maps.event.addListener(map, 'resize', function() {
this.setZoom(13);
this.setCenter(myLatlng);
var infowindow = new google.maps.InfoWindow({
content: WINDOW_HTML
});
var marker = new google.maps.Marker({
position: myLatlng,
map: map
});
google.maps.event.addListener(marker, 'click', function() {
infowindow.open(map,marker);
});
infowindow.open(map,marker);
});
/* Check Streetview is available */
var streetViewService = new google.maps.StreetViewService();
var STREETVIEW_MAX_DISTANCE = 50;
streetViewService.getPanoramaByLocation(myLatlng, STREETVIEW_MAX_DISTANCE, function (streetViewPanoramaData, status) {
if (status === google.maps.StreetViewStatus.OK) {
function svcheck() {
var panoramaOptions = {
position: myLatlng,
pov: {
heading: 34,
pitch: 10
},
visible:true
}
var panorama = new google.maps.StreetViewPanorama(document.getElementById('pano'),panoramaOptions);
map.setStreetView(panorama);
// Tab fix for streetview refresh
$('#svTab').on('shown', function (e) {
$('#pano').show();
panorama.setVisible(true);
});
}
svcheck();
} else {
/* Street view is unavailable - HIDE THE TAB! */
$('#svTab').hide();
}
});
}
google.maps.event.addDomListener(window, 'load', initialize);
