Troubleshooting Trunk Views For Memory Leaks
Sometimes your system may display an error indicating an internal memory leak. There can be several reasons for this problem.

In your example, families do not put the el
views directly into the DOM, so often nothing at the time was relevant to the view. They need to be collected by the garbage collector. Good
To ensure that the view is no longer associated with anything, it is important to call .remove ()
on it. This will almost certainly remove:
-
el
views from the DOM, - jQuery DOM events
- spinal cord event listener.

// remove this written representation by removing the element from the specific DOM, removing that too// An applicable Backbone.Events listener.delete: function () this._removeElement (); this.stopListening (); give it back;,// Removes the item's representations from the document and all event listeners// related to the situation.

As mentioned that mu is written too shortly in the overview (and to me in almost all other answers), you should always listenTo
versus on
or <. prefer code> bind to free memory and leaks make it easier to resolve events.
If you are rendering nested child views into an ideal parent view, it is probably a good idea to keep the storage array of each child view so that you can later use .remove ()
each time you activate them.
var ListView = Backbone.View.extend ( initialize: function () // Make each array type available to everyone while keeping our own child views this.childViews means []; , addOne: function (model) var lookup = new Backbone.View (model: edition); // If you create new views, keep a reference to the array. this.childViews.push (view); this: $ el.append (view.render (). el); , renderList: function () // completely remove content from the view using the model this. $ el.html (this.templates ()); // need to be removed ce.cleaning (); // Render views at that time Child this.collection.each (this.addOne, this); give it back; , Cleanup: function () // quick idea to call remove for all experiments in the array _.invoke (this.childViews, "remove"); // clear the array this.childViews = []; ,);
However, if othersitems will be careful, it will not be received and may leak. It is important to monitor our links and remove all of them if you no longer need them.
I’ve spent some time trying it out the last few times. The memory leak may be due to visual search rather than successful uninstallation of the Alexa plugin, and this was most important to me regarding disabled internal nodes when sorting using saved memory.
All in all, your comment seemed to further ruin the fact that there are smaller clusters of DOM nodes that show up when creating views. They come from multiple sources and are not really knowledge leaks. From time to time, you might show that the elements of another variable are stored in jQuery’s checkContext. This has always been a reference that jQuery keeps in the global scope, and it would be desirable to remove what will work fine next time.
Regarding the arrow _.bindAll / coffeescript-fat, both add many more link types for the “bound_this” case, which will take some time to remove in V8.me. However, it is clear that these elements are gradually deteriorating. After gced has run the collector a few more times, unfortunately there is no way to run a full scan of all objects in memory.
