webgl对多个数据服务进行点击查询

通过iServer发布的多个数据服务,怎么进行属性查询?

http://qa.supermap.com/44657这个里面是对一个数据服务进行查询,此方式是可以实现的,现在我有3个数据服务,我用循环遍历服务,但是查询不到内容。

 var Cesium = window.Cesium;
        var _this = thisMapCon;
        var viewer = window.CesiumViewer;
        //todo: yjw添加数据服务
        var scene = viewer.scene;
        var widget = viewer.cesiumWidget;

        var supScene=URL_CONFIG.SupScene;
        for (var i=0;i<supScene.length;i++) {
            if (supScene[i].GWServerUrl!=undefined) {
                //变量1
                // var promise = tempp[URL_CONFIG.qxsyName];
                var promise = tempp[supScene[i].key];
                try {
                    Cesium.when(promise, function (layers) {
                        if (!scene.pickPositionSupported) {
                            alert('不支持深度拾取,属性查询功能无法使用!');
                        }
                        // var testLayer = viewer.scene.layers;
                        for (var i = 0; i < layers.length; i++) {
                            var strLayer = scene.layers.findByIndex(i).name;
                            var layer = scene.layers.find(strLayer);
                            // layer.selectEnabled=false;
                            var str_before = strLayer.split("@")[0];
                            //设置属性查询参数
                            layer.setQueryParameter({
                                //变量2和变量3
                                // url: URL_CONFIG.dataSerUrl,
                                // dataSourceName: URL_CONFIG.dataSourceName,
                                url: supScene[i].DataSerUrl,
                                dataSourceName: supScene[i].DataSourceName,
                                dataSetName: str_before,
                                keyWord: 'SmID'
                            });
                        }

                    }, function (e) {
                        if (widget._showRenderLoopErrors) {
                            var title = '渲染时发生错误,已停止渲染。';
                            widget.showErrorPanel(title, undefined, e);
                        }
                    });
                } catch (e) {
                    if (widget._showRenderLoopErrors) {
                        var title = '渲染时发生错误,已停止渲染。';
                        widget.showErrorPanel(title, undefined, e);
                    }
                }

可以在各个服务的数据中,新添加一个字段,通过查询该字段的方式获取属于某个服务
