问题描述
我正在处理这张地图,并尝试对大约150个标记进行地理编码,但是我正在使用地理编码限制。如何添加时间延迟以避免触及限制?
解决方案
这为地理编码添加了一个计时器,因此每个标记都有一个延迟。
//为每个城市添加一个LatLng对象
函数geocodeAddress(i){
geocoder .geocode({'address':address [i]},function(results,status){
if(status == google.maps.GeocoderStatus.OK){
places [i] = results [ 0] .geometry.location;
//添加标记
var marker = new google.maps.Marker({position:places [i],map:map});
markers.push(marker);
mc.addMarker(marker);
//创建事件侦听器,它现在可以访问i和marker的值它的创建
google.maps.event.addListener(marker,'click',function(){
//检查我们是否已经有InfoWindow
if(! infowindow){
infowindow = new google.maps.InfoWindow();
}
//设置InfoWindow的内容
infowindow.setContent(popup_content [i]);
//将InfoWindow绑定到标记
infowindow.open(map,marker);
});
//用每个LatLng
bounds.extend(places [i])扩展边界对象;
//将地图调整到新的边界框
map.fitBounds(bounds)
} else {
alert(地理编码不成功,原因如下: +状态); (){
}
})
}
函数geocode(){
if(geoIndex< address.length){
geocodeAddress(geoIndex );
++ geoIndex;
}
else {
clearInterval(geoTimer);
}
}
var geoIndex = 0;
var geoTimer = setInterval(geocode,200); // 200毫秒(试用)
var markerCluster = new MarkerClusterer(map,markers);
}
})
();
< / script>
ADDED。上述程序可以调整。
(1)时间间隔可以缩短:
var geoTimer = setInterval(geocode,100); (2)函数geocode()可以在每个请求上执行多个请求时间间隔,例如5个请求:
函数geocode(){
for(var k = 0; k< 5& amp ; geoIndex< address.length; ++ k){
geocodeAddress(geoIndex);
++ geoIndex;
}
if(geoIndex> = address.length){
clearInterval(geoTimer);
}
}
I'm working on this map and trying to geocode around 150 markers but I'm hitting the geocode limit. How can I add a time delay to avoid hitting the limit?
解决方案 This adds a timer to the geocoding so each marker has a delay.
// Adding a LatLng object for each city
function geocodeAddress(i) {
geocoder.geocode( {'address': address[i]}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
places[i] = results[0].geometry.location;
// Adding the markers
var marker = new google.maps.Marker({position: places[i], map: map});
markers.push(marker);
mc.addMarker(marker);
// Creating the event listener. It now has access to the values of i and marker as they were during its creation
google.maps.event.addListener(marker, 'click', function() {
// Check to see if we already have an InfoWindow
if (!infowindow) {
infowindow = new google.maps.InfoWindow();
}
// Setting the content of the InfoWindow
infowindow.setContent(popup_content[i]);
// Tying the InfoWindow to the marker
infowindow.open(map, marker);
});
// Extending the bounds object with each LatLng
bounds.extend(places[i]);
// Adjusting the map to new bounding box
map.fitBounds(bounds)
} else {
alert("Geocode was not successful for the following reason: " + status);
}
})
}
function geocode() {
if (geoIndex < address.length) {
geocodeAddress(geoIndex);
++geoIndex;
}
else {
clearInterval(geoTimer);
}
}
var geoIndex = 0;
var geoTimer = setInterval(geocode, 200); // 200 milliseconds (to try out)
var markerCluster = new MarkerClusterer(map, markers);
}
})
();
</script>
ADDED. The above program can be tuned.
(1) The time interval can be reduced:
var geoTimer = setInterval(geocode, 100); // do requests each 100 milliseconds
(2) The function geocode() could perform several requests at each time interval, e.g. 5 requests:
function geocode() {
for (var k = 0; k < 5 && geoIndex < address.length; ++k) {
geocodeAddress(geoIndex);
++geoIndex;
}
if (geoIndex >= address.length) {
clearInterval(geoTimer);
}
}
