Question

有人可以帮我解决这个问题。上面的代码有什么不对，它不会显示任何错误但集群层没有显示。剩余的功能正在运行。我正在使用这个例子https://github.com/nickcam/FlareClusterLayer

var dojoConfig = {
    async: true,
    packages: [{
        name: 'extras',
        location: location.pathname.replace(/[^\/]+$/, '') + 'JS/extras'
    }]
};

var findTask, findParams;

ready(function () {
    parser.parse();

    var clusterLayer;

    // registry.byId("ddlDistrict").on("onchange", doFind);
    var intialextent = new Extent(8245227.8765913, 1297819.43274543, 8758703.79511306, 2095175.01113784, new SpatialReference({ wkid: 102100 }));

    var AgricultureBoundary = new ArcGISDynamicMapServiceLayer("http://[myserver]/arcgisserver/rest/services/CRD/CRD1/MapServer", {
        opacity: 0.75
    });
    var pointFeatureLayer = new FeatureLayer("http://[myserver]/arcgisserver/rest/services/CRD/CRD2/FeatureServer/0", {
        id: "Points"
    });
    map = new Map("mapDiv", {
        center: [77.2, 14],
        zoom: 7,
        extent: intialextent,
        basemap: "streets",
    });

    map.addLayers([AgricultureBoundary, pointFeatureLayer]);

    var queryTask = new esri.tasks.QueryTask("http://[myserver]/arcgisserver/rest/services/CRD/CRD2/FeatureServer/0");
    var query = new esri.tasks.Query();
    query.returnGeometry = true;
    query.where = "pointcollected  = 'No'";
    query.outFields = ["*"];
    dojo.connect(queryTask, "onComplete", function (featureSet) {
        var inputInfo = {};
        inputInfo.data = dojo.map(featureSet.features, function (feature) {
            var pointX = feature.geometry.x;
            var pointY = feature.geometry.y;
            var att = feature.attributes;
            return { "x": pointX, "y": pointY, "attributes": att };
        });

        clusterLayer = new ClusterFeatureLayer({
            "data": inputInfo.data,
            "distance": 1,
            "id": "clusters",
            "labelColor": "#fff",
            "labelOffset": 10,
            "resolution": map.extent.getWidth() / map.width,
            "singleColor": "#888",
            "singleTemplate": infoTemplate
        });
        var defaultSym = new esri.symbol.SimpleMarkerSymbol().setSize(4);
        var renderer = new esri.renderer.ClassBreaksRenderer(defaultSym, "clusterCount");
        var blue = new esri.symbol.PictureMarkerSymbol("http://static.arcgis.com/images/Symbols/Shapes/BluePin1LargeB.png", 32, 32).setOffset(0, 15);
        var green = new esri.symbol.PictureMarkerSymbol("http://static.arcgis.com/images/Symbols/Shapes/GreenPin1LargeB.png", 64, 64).setOffset(0, 15);
        var red = new esri.symbol.PictureMarkerSymbol("http://static.arcgis.com/images/Symbols/Shapes/RedPin1LargeB.png", 72, 72).setOffset(0, 15);
        renderer.addBreak(0, 2, blue);
        renderer.addBreak(2, 200, green);
        renderer.addBreak(200, 1001, red);
        clusterLayer.setRenderer(renderer);
        map.addLayer(clusterLayer);
    });
});

在构造函数中传递数据不会做任何事情（虽然它可能应该处理它）。

请尝试以下方法：

dojo.connect(queryTask, "onComplete", function (featureSet) {
    var inputInfo = {};
    inputInfo.data = dojo.map(featureSet.features, function (feature) {
        var pointX = feature.geometry.x;
        var pointY = feature.geometry.y;
        var att = feature.attributes;
        return { "x": pointX, "y": pointY, "attributes": att };
    });

    clusterLayer = new ClusterFeatureLayer({
        "distance": 1,
        "id": "clusters",
        "labelColor": "#fff",
        "labelOffset": 10,
        "resolution": map.extent.getWidth() / map.width,
        "singleColor": "#888",
        "singleTemplate": infoTemplate
    });
    var defaultSym = new esri.symbol.SimpleMarkerSymbol().setSize(4);
    var renderer = new esri.renderer.ClassBreaksRenderer(defaultSym, "clusterCount");
    var blue = new esri.symbol.PictureMarkerSymbol("http://static.arcgis.com/images/Symbols/Shapes/BluePin1LargeB.png", 32, 32).setOffset(0, 15);
    var green = new esri.symbol.PictureMarkerSymbol("http://static.arcgis.com/images/Symbols/Shapes/GreenPin1LargeB.png", 64, 64).setOffset(0, 15);
    var red = new esri.symbol.PictureMarkerSymbol("http://static.arcgis.com/images/Symbols/Shapes/RedPin1LargeB.png", 72, 72).setOffset(0, 15);
    renderer.addBreak(0, 2, blue);
    renderer.addBreak(2, 200, green);
    renderer.addBreak(200, 1001, red);
    clusterLayer.setRenderer(renderer);
    map.addLayer(clusterLayer);
    clusterLayer.addData(inputInfo.data);
});
