javascript - 如何在 bingmap 中推送 2044 个邮政编码而不出现错误表达式太长或复杂而无法编译？

Question

我正在尝试在 bingmaps 中制作所有荷兰 (4044) 邮政编码的多边形。每个邮政编码有 10 到 1000 个坐标。我尝试了以下代码，它适用于大约 200 个邮政编码:

var polygoncolor = new Microsoft.Maps.Color(100, 255, 0, 0);
var  pc1011 = new Array (
new Microsoft.Maps.Location(52.372203,4.913825),
new Microsoft.Maps.Location(52.375787,4.912745),
new Microsoft.Maps.Location(52.37605,4.911752));         
var polygon1011 = new Microsoft.Maps.Polygon(pc1011  , {
            fillColor: polygoncolor,
            strokeColor: polygoncolor
        });
map.entities.push(polygon1011);

我也尝试过这个，这就是我喜欢看到它工作的原因:

var myMappings = [
{  pc: "1011", coor: new Array(
     new Microsoft.Maps.Location(52.365669,4.901578),
     new Microsoft.Maps.Location(52.372203,4.913825),
     new Microsoft.Maps.Location(52.378387,4.905391)
)},
  {     
    pc: "1012", coor: new Array(
    new Microsoft.Maps.Location(52.381136,4.89783),
    new Microsoft.Maps.Location(52.372203,4.913825),
    new Microsoft.Maps.Location(52.382393,4.900011)
)}];

for (var i = 0; i < myMappings.length; i += 1) {
     var polygoncolor = new Microsoft.Maps.Color(100, 0, 0, 100);
     var polygon = new Microsoft.Maps.Polygon(myMappings[i].coor, {
       fillColor: polygoncolor,
       strokeColor: polygoncolor
     });
     map.entities.push(polygon);

}

两者都适用于有限的邮政编码。但是当我尝试推送超过~300个邮政编码/多边形和~200个坐标时，它会返回下面的错误。我正在使用 Visual Studio .net 和 bingmaps。有谁知道如何修复这个错误？或者也许有一个完整的其他解决方案来显示所有荷兰邮政编码？“/”应用程序中的服务器错误。

以前没有见过这个错误。看起来像 ASP.NET 中的东西。无论如何，尝试渲染 4044 个邮政编码多边形(每个多边形有 200 个坐标)是行不通的。 JavaScript 无法处理太多的数据。这会创建大量 DOM 对象，并且每次 map 移动时都会重新投影大量数据。对于用户来说，下载的内容也相当大(猜测大小超过 9MB)。

也就是说，使用正确的架构可以在 Bing map 上可视化数百万个多边形。诀窍是将数据转换为图 block (图像组)。这样浏览器一次只需处理几个图像。这显着减少了用户必须下载的数据量。这是我制作的演示，它渲染了 175,000 个多边形，每个多边形有 200 个以上坐标: http://onsbingmapsdemo.cloudapp.net/在此示例中，将图钉拖动到多边形上以检索有关它的一些信息。我也可以只使用鼠标点击，但我想在这个应用程序中尝试一些不同的东西。

有几种方法可以生成这些图 block 层。这里有一个开源MVC应用程序:http://ajaxmapdataconnector.codeplex.com/

我还有一份尚未发布的白皮书，其中介绍了如何执行此操作。如果您向 Hotmail.com 的 ricky_brundritt 发送电子邮件，我将向您发送一份论文和代码示例的副本。
