ロケーションのリストを距離(リストに表示)でソートしたい。私はすでに動作するコードを持っていますが、mvc 全体に慣れていないので、動作させるためにどこに配置すればよいかわかりません。
多分誰かが私を助けることができます:
var geocoder = new google.maps.Geocoder();
var geo = Ext.create('Ext.util.Geolocation',{
autoUpdate: false,
listeners: {
locationupdate:{
scope: this,
fn: function(geo){
var haversindeDistance = function(lat1,lon1,lat2,lon2){
if(typeof(Number.prototype.toRad)=="undefined"){
Number.prototype.toRad = function(){
return this * Math.PI/180;
}
}
var R = 6371; //km
var dLat = (lat2-lat1).toRad();
var dLon = (lon2-lon1).toRad();
var lat1 = lat1.toRad();
var lat2 = lat2.toRad();
var a = Math.sin(dLat/2)*Math.sin(dLat/2)+
Math.sin(dLong/2)*Math.sin(dLon/2)*Math.cos(lat1)*Math.cos(lat2);
var c = 2*Math.atan2(Math.sqrt(a),Math.sqrt(1-a));
var d = R*c;
// KM or MIles
//return d*0.621371192; //MIles
return d;
};
var store = Ext.getStore('locationsstore');
store.suspendEvents(true);
store.each(function(location){
var lat2 = parseFloat(location.get(geocoder.geocode( { 'address': sAddress}, function(results, status) { })))||0;
var lon2 = parseFloat(location.get(geocoder.geocode( { 'address': sAddress}, function(results, status) { })))||0;
//var lat2 = parseFloat(location.get('lat'))||0;//try to put geocode on this ish
//var lon2 = parseFloat(location.get('lon'))||0;
if(lat2 && lon2){
var distance = haversineDistance(geo.getLatitude(),geo.getLongitude(),lat2,lon2);
location.set('distance',distance);
}
}, this);
store.resumeEvents();
store.filter('distance',/\d/);
store.sort('distance');//check if it is not done or can not be done somewhere else
list.setMasked(false);
}
},
locationerror:{
scope: this,
fn:function(geo,bTimeout,bPermissionDenied,bLocationUnavailable,message){
console.log([geo,bTimeout,bPermissionDenied,bLocationUnavailable,message]);
if(bTimeout){
Ext.Msg.alert('Timed out getting your location.');
}else{
Ext.Msg.alert('Error getting location. Please make sure location services are enabled on your Device.');
}
list.setMask(false);
}
}
}
});
geo.updateLocation();
