Navigating through Ember.js with the help of Google Maps integration

I have successfully implemented Google Maps on my main page and now I am trying to do the same for one of my inner pages.

var MapView = Ember.View.extend({
    layoutName: 'pagelayout',
    didInsertElement : function(){
          var mapOptions = {
            center: new google.maps.LatLng(-34.397, 150.644),
            zoom: 8,
            mapTypeId: google.maps.MapTypeId.ROADMAP
            };
          var map = new google.maps.Map(this.$("#map").get(0),mapOptions);
          this.set('map',map); 
        },
        redrawMap : function(){
          var newLoc = new google.maps.LatLng(this.get('latitude'), this.get('longitude'));
          this.get('map').setCenter(newLoc)
        }.observes('latitude','longitude') 

}); 

However, the map is not rendering on the inner page. If I make a slight change as shown above, it works but takes over the base html element inappropriately.

this.$().get(0) /**from this.$('#map').get(0)**/

I am struggling to figure out the issue. I considered that maybe the didInsertElement event was being triggered too early, even though I thought the entire DOM would be available by then for this View. I tried setting up an afterRender listener and triggering the map load, but that also failed. I have confirmed multiple times that the div exists.

Could someone assist me with solving this problem?

Answer №1

When I tried running the Google Maps initialization code from my console, I noticed that the map loaded successfully. This led me to believe that there might be an issue with how the didInsertElement function was interacting with my setup. Initially, I thought that didInsertElement was triggered when the View was inserted into the DOM, but it seems like its behavior differs when using layouts.

To resolve this issue, I decided to call a separate view directly within the div itself:

{{#view "map"}}

I also created a new View specifically for the map:

var MapView = Ember.View.extend({
 /**
 Same as previous code
**/
});

This workaround worked for me and could potentially help others facing a similar problem. If you have a better solution, feel free to share it so I can test it out and possibly give it an upvote.

Answer №2

It's possible that this.$() is not available because the view hasn't finished rendering yet. To solve this, you can use Ember.run.next to delay the execution until the next run loop cycle:

didInsertElement: function() {
    Ember.run.next(this, function() {
        // your code here
    });
});
