添加时间延迟谷歌地图地理编码 [英] Adding time delay to google map geocode

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);
    }
}
