InfoQuery

在框选的范围内对指定图层进行信息查询

See:

./manual/query.html

Example:

var infoQuery = KQ.Query.InfoQuery.getInstance();
var options = {
  url: 'http://172.16.1.157:8699/KQGis/rest/services/zy',
  layerId: 145,
  reqcount: '200',
  sr: '',
  geometry: '{"type":"Polygon","coordinates":[[[104.94105475249448,29.97276304931208],[104.94105475249448,30.028839993667194],[105.00551176529433,30.028839993667194],[105.00551176529433,29.97276304931208],[104.94105475249448,29.97276304931208]]]}',
  fields: 'OBJECTID,XZBM,BSM,YSDM,JXLX,JXXZ,JXSM,BGRQ',
  f: 'json',
  where: '',
};

infoQuery.queryAsync(options,
function query_good () {
  console.log('query_good');
},
function query_error () {
  console.log('query_error');
});
