谷歌地图如何修复OVER_QUERY_LIMIT错误

Question

我尝试在每个循环中使用setTimeout：$("#dropdown option").each(function ()但是有些原因不起作用，这里是mu代码：

function initialize() {
    var map = new google.maps.Map(document.getElementById("map"));
    var geocoder = new google.maps.Geocoder();
    $("#dropdown").change(function () {
        address = $("#dropdown :selected")[0].text;
        geocodeAddress(address, geocoder, map);
    });
    var address = $("#dropdown :selected")[0].text;
    $("#dropdown option").each(function ()
    {
        setTimeout(function () {
            geocodeAddress($(this).text() + ' ,Montenegro', geocoder, map);
        }, 1000);
    });
    geocodeAddress(address, geocoder, map);
}
google.maps.event.addDomListener(window, "load", initialize);

function geocodeAddress(address, geocoder, resultsMap) {
    document.getElementById('info').innerHTML = address;
    geocoder.geocode({
        'address': address
    }, function (results, status) {
        if (status == google.maps.GeocoderStatus.OVER_QUERY_LIMIT) {
            console.log(google.maps.GeocoderStatus)
        }

        if (status === google.maps.GeocoderStatus.OK) {
            resultsMap.fitBounds(results[0].geometry.viewport);
            var marker = new google.maps.Marker({
                map: resultsMap,
                position: results[0].geometry.location
            });
            document.getElementById('info').innerHTML += "<br>" + results[0].geometry.location.toUrlValue(6);
        } else {
            alert('Geocode was not successful for the following reason: ' + status);
        }
    });
}

任何人都知道什么是问题？

1. 您需要对要进行地理编码的地址进行功能关闭
2. 您需要更改延迟，以便所有超时都不会同时到期。

var timeout = 0;
$("#dropdown option").each(function ()
{
    // update timeout, so don't all expire at the same time
    timeout = timeout+1000;
    // get function closure on the address for this entry
    var address = $(this).text();
    console.log(address);
    setTimeout(function () {
        geocodeAddress(address + ' ,Montenegro', geocoder, map);
    }, timeout);
});
