Question

我正在寻找一种方法来使用我当前设置的framecloud类型弹出窗口。不幸的是，我的所有尝试都没有起作用，或者只适用于最近放置的制造商。

在尝试使其工作的过程中，我已将原始脚本从使用标记转换为使用向量来放置标记点（正如我所见，自定义向量比标记更容易。）

现在哪一个我可以开始工作，我会使用，但在这个工作了几天之后我就会在我的智慧结束时需要帮助正确的方向。

使用tabletop.js从谷歌电子表格中提取我的观点。该功能正在按照我的意愿工作，标记根据我称为“类型”的字段放置在各自的图层上。虽然我有一种感觉可能是我的Markers类型层问题的根源，但我不确定如何修复它。

我终于开始工作了。对于处于类似情况的人来说，这是我的最终代码。我确实从最初的图层更改了图层的名称，并将我使用的电子表格涂黑了，但更改应该是显而易见的。

//
//// Set 'Markers'

            var iconMarker = {externalGraphic: 'http://www.openlayers.org/dev/img/marker.png', graphicHeight: 21, graphicWidth: 16};
            var iconGeo = {externalGraphic: './images/fortress.jpg', graphicHeight: 25, graphicWidth: 25};
            var iconAero = {externalGraphic: './images/aeropolae.jpg', graphicHeight: 25, graphicWidth: 25}; // Image is the creation of DriveByArtist: http://drivebyartist.deviantart.com/

            var vector1 = new OpenLayers.Layer.Vector("1");
            var vector2 = new OpenLayers.Layer.Vector("2");
            var vector3 = new OpenLayers.Layer.Vector("3");


// Pulls map info from Spreadsheet

        Tabletop.init({
          key: 'http://xxxxxxxxxx', //Spreadsheet URL goes here
          callback: function(data, tabletop) { 
            var i,
                dataLength = data.length;

            for (i=0; i<dataLength; i++) { //following are variables from the spreadsheet
                locName = data[i].name;
                locLon = data[i].long;
                locLat = data[i].lat;
                locInfo = data[i].info;
                locType = data[i].type; // Contains the following string in the cell, which provides a pre-determined output based on provided information in the spreadsheet: =ARRAYFORMULA("<h2>"&B2:B&"</h2><b>"&G2:G&"</b><br /> "&C2:C&", "&D2:D&"<br />"&E2:E&if(ISTEXT(F2:F),"<br /><a target='_blank' href='"&F2:F&"'>Read More...</a>",""))

                locLonLat= new OpenLayers.Geometry.Point(locLon, locLat);

               switch(locType)
                {

                     feature = new OpenLayers.Feature.Vector(

          },
          simpleSheet: true

        };

        function createPopup(feature) {
          feature.popup = new OpenLayers.Popup.FramedCloud("pop",
              feature.geometry.getBounds().getCenterLonLat(),
              null,
              '<div class="markerContent">'+feature.attributes.description+'</div>',
              null,
              true,
              function() { controls['selector'].unselectAll(); }
          );
          feature.popup.autoSize = true;
          feature.popup.minSize = new OpenLayers.Size(400,100);
          feature.popup.maxSize = new OpenLayers.Size(400,800);
          feature.popup.fixedRelativePosition = true;
          feature.popup.overflow ="auto";
          //feature.popup.closeOnMove = true;
          map.addPopup(feature.popup);
        }

        function destroyPopup(feature) {
          feature.popup.destroy();
          feature.popup = null;
        }

        map.addControl(controls['selector']);
        controls['selector'].activate();

        }
