我有以下代码,它应该为数组中的位置显示多个标记,并且单击每个标记将显示一个信息窗口一切正常,但21个地方中我只能显示8个标记。
// declare Variables
var geocoder;
var map;
var tex;
var markersArray = [];
// pids array 21 addreses
var pids = [{ad:'251 Pantigo Road Hampton Bays NY 11946',pid:'9'},

答案 0 :(得分:9)
如果您取消注释
// alert("Geocode was not successful for the following reason: " + status);
你会发现reason code是OVER_QUERY_LIMIT
(620)。
存在速率限制:如果您对许多地址进行地理编码而不会在它们之间引入延迟,那么您将打破该限制,因为您在太短的时间内做了太多。
您的某些地址不会进行地理编码(或不会产生您想要的结果),因为地理编码器使用邮政地址。 地址East Hampton NY 11937 或道具地址Westhampton Dunes NY 11978 等地址不是邮寄地址。
建议的策略不是浪费您与他人共享的Google资源。通过一次性操作自己对地址进行地理编码,将这些位置存储在数据库中(或直接在代码中使用它们),然后使用坐标来定位标记。每次加载页面时,都不必费心去寻找您已经知道的位置。仅使用地理编码器查找您事先不知道的位置:用户输入的地址。
如果您真的必须颠覆该策略并始终对所有内容进行地理编码,那么您需要降低请求速度。当您提交更多请求时,您可能需要将它们放慢速度以满足地理编码器的要求。我在http://acleach.me.uk/gmaps/v3/plotaddresses.htm创建了一个版本3示例(来自着名的第2版示例) - 您可以看到它在请求之间延迟100毫秒,但需要在二十次迭代后减慢到大约150毫秒。
