重新加载页面时，Kml图层不会更新 [英] Kml layers doesn't update when reloading the page

问题描述

似乎问题来自谷歌地图，需要一些时间来更新KML链接...我不确定，但最终，它的工作原理... [/编辑]

我在此网站上嵌入现有的公开Goog​​le地图： http：// www。 ridetheflavour.fr

以下是公共地图的链接： https://maps.google.fr/maps/ms?msa=0&msid=211027213468691902621.0004c8616605648d245b2

如您所见，网站嵌入式地图的标记与公开的Google地图标记不匹配。看起来这不是浏览器缓存的问题......

以下是我使用的JavaScript片段（Google map API V3）：

  var mapOptions = {
 center：new google.maps.LatLng（24.797409，-5.449219），
 zoom：3，
 mapTypeId：google.maps.MapTypeId.TERRAIN，
 overviewMapControl：false，
 streetViewControl：false 
}; 
 var map = new google.maps.Map（document.getElementById（map_canvas），
 mapOptions）; 
 var georssLayer = new google.maps.KmlLayer（'https://maps.google.fr/maps/ms?ie=UTF8&authuser=0&msa=0&output=kml&msid=211027213468691902621.0004c8616605648d245b2' ）; 
 georssLayer.setMap（map）; 
  

任何帮助将不胜感激。

解决方案

Google的服务器缓存KML内容一段时间。要强制更新呈现的KML，请在URL中添加缓存清除参数。我通常使用日期/时间的函数，如果我需要以编程方式执行它，或者如果它只是一次性编辑手册？a = 0并且随着我进行更改而增加它。

类似这样（如果URL中没有其他查询参数）：

  var URL = filename +？dummy =+（new Date（））。getTime（）; 
  

[EDIT] it seems the problem comes from google maps which takes some time to update the KML link...I'm not sure, but in the end, it works...[/EDIT]

I embedded an existing public google map on this website : http://www.ridetheflavour.fr

Here is the link of the public map : https://maps.google.fr/maps/ms?msa=0&msid=211027213468691902621.0004c8616605648d245b2

As you can see, the markers of the website's embedded map don't match the public google map markers. It seems it's not a matter of browser cache...

Here is the javascript snippet i'm using (Google map API V3) :

var mapOptions = {
          center: new google.maps.LatLng(24.797409,-5.449219),
          zoom: 3,
          mapTypeId: google.maps.MapTypeId.TERRAIN,
          overviewMapControl: false,
          streetViewControl: false
        };
var map = new google.maps.Map(document.getElementById("map_canvas"),
            mapOptions);
var georssLayer = new google.maps.KmlLayer('https://maps.google.fr/maps/ms?ie=UTF8&authuser=0&msa=0&output=kml&msid=211027213468691902621.0004c8616605648d245b2');
georssLayer.setMap(map);

Any help would be greatly appreciated.

解决方案

Google's servers cache the KML content for some period of time. To force the rendered KML to update, add a cache busting parameter to the URL. I usually use a function of the date/time if I need to do it programmatically, or if it is just a one time edit a manual ?a=0 and incrementing that as I make changes works.

Something like this (if you don't have any other query parameters in the URL):

 var URL = filename+"?dummy="+(new Date()).getTime();
