Body
<p>i want to sort a list of Locations by its Distance(displayed in list). i already have a code that sould work but since i am that new to the whole mvc thing, i am not really sure where to place it to make it work.</p> <p>Maybe someone can help me:</p> <pre><code> 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(); </code></pre>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
