ArcGIS API For Javascript 之 QueryTask单图层查询

require([
            "esri/tasks/QueryTask","esri/tasks/query","esri/SpatialReference"
        ], function(QueryTask,Query,SpatialReference) {
            var queryTask =new QueryTask("http://localhost/arcgis/rest/services/ed/123/MapServer/0");
            var query=new Query();
            query.returnGeometry=true;
            query.outSpatialReference=new SpatialReference({wkid:4326});
            query.outFields=["*"];//"*"表示查询所有属性。查询个别属性query.outFields=["属性1","属性2",...,"属性n"]
            query.where="DKMC like "+"'%某一个值%'";//模糊查询
            queryTask.execute(query,function(fs){
    
                // var ds=fs.features;
                //如果查询成功并有返回值，控制台输出其他属性
                if(fs){                
					console.log(fs)；
                    });
                }else{
