【解决办法】采用ajax请求，设置geometry属性中”points":["y":y,"x":x]即可
参考代码：
var geometry = {
"points " :[{ "y" :y , "x":x}]，"type" : "POINT"
}
var sqlParameter = i
datasetNames:[ "huianxian : NewDataset"]，getFeatureMode: "SPATIAL",
spatialQueryMode: "INTERSECT",geometry: geometry
};
var queryData = JSON.stringify(sqlParameter) ; / ajax请求
$.ajax({
type: 'post ',url: dataURL,data: queryData,
success : function ( result) {
var resultobj = JSON . parse ( result);if(resultobj.featureCount){
alert("点落在范围内");
},
error: function (msg) {
console.log(msg);
}
})
