下面是一段模糊查询，可以查询到某地并且高亮显示，点击可查询其信息；但是由WGS84换为北京54坐标系后，该功能不能实现了，请帮我查看一下什么原因。
//地点查询 开始
var searchMarkerLayer, searchmarker, searchVectorLayer;
function search() {
var searchContent = document.getElementById("searchCon").value;
if (searchContent.length <= 0) {
alert("请输入查询地点");
return;
}
searchVectorLayer = new SuperMap.Layer.Vector("searchVectorLayer");
searchMarkerLayer = new SuperMap.Layer.Markers("searchMarkerlayer");
map.addLayer(searchMarkerLayer);
map.addLayer(searchVectorLayer);
var queryParam, queryBySQLParams, queryBySQLService;
var layerName = ["XIUXIAN@China400"];
//FilterParameter 必设 name（查询地图图层名），attributeFilter（SQL条件语句）也为必设 "RoomID like '%" + searchContent + "%'"
for (var i = 0; i < layerName.length; i++) {
queryParam = new SuperMap.REST.FilterParameter({
name: layerName[i],
attributeFilter: "NAME like '%" + searchContent+"%'", fields:"SmID","EAST","NORTH","NAME","LOCATION","INTRODUCE"]
});
//QueryBySQLParameters 参数必设queryParams
queryBySQLParams = new SuperMap.REST.QueryBySQLParameters({ queryParams: [queryParam] });
queryBySQLService = new SuperMap.REST.QueryBySQLService(url, { eventListeners: { "processCompleted": searchprocessCompleted, "processFailed": searchprocessFailed} });
queryBySQLService.processAsync(queryBySQLParams);
}
}
function searchprocessFailed(e) {
//alert("404");
alert(e.error.errorMsg);
}
function searchprocessCompleted(queryEventArgs) {
var result = queryEventArgs.result;
//显示查找到的矢量要素
alert(result.totalCount);
if (result && result.totalCount > 0) {
alert("404");
for (i = 0; i < result.recordsets.length; i++) {
if (result.recordsets[i].features) {
for (j = 0; j < result.recordsets[i].features.length; j++) {
console.log("**" + result.recordsets[i].features[j].attributes["EAST"]);
feature = result.recordsets[i].features[j];
feature.style = style;
searchVectorLayer.addFeatures(feature);
clickSelectInfo = "名称：" + feature.attributes["NAME"] + "<br/>" + "地址：" + feature.attributes["LOCATION"] + "<br/>" + "介绍:" + feature.attributes["INTRODUCE"] + "<br/>";
var north = result.recordsets[i].features[j].attributes["NORTH"];
// var south = result.recordsets[i].features[j].attributes["SmSdriS"];
// var west = result.recordsets[i].features[j].attributes["SmSdriW"];
var east = result.recordsets[i].features[j].attributes["EAST"];
var x = parseFloat(north);
var y = parseFloat(east);
// alert(x + "," + y);//4340521,507528
console.log("x:"+x);
var size = new SuperMap.Size(44, 33);
var offset = new SuperMap.Pixel(-(size.w / 2), -size.h);
icon = new SuperMap.Icon('../theme/images/marker.png', size, offset);
searchmarker = new SuperMap.Marker(new SuperMap.LonLat(y,x), icon);
searchMarkerLayer.addMarker(searchmarker);
map.setCenter(new SuperMap.LonLat(y, x), 2);
searchmarker.events.on({
"click": clickSelectmouseClickHandler
// "touchstart": mouseClickHandler //假如要在移动端的浏览器也实现点击弹框，则在注册touch类事件
});
}
}
}
} else {
// resultTable = "<p>无查询结果！</p>";
}
}
