The nodejs server is reachable from the host server on port 8080. The nginx docker container is listening to port 80 (will do the certificate later, first this base must be working). And now I want a subdomain to be forwarded to this 8080 nodejs app. lets say app1.example.com From outside I can reach the app by te server ip (or hostname) and port 8080 but not on app1.example.com. And it does work on app1.example.com:8080 (I have opened up port 8080 on the

Whenever I declare a view and run BDD test with jasmine, it always returns "undefined is not a function". This is code window.LocationView = Backbone.View.extend({ initialize: function() { // create new marker first this.marker = new google.maps.Marker({ title: this.model.get('name'), draggable: true, animation: google.maps.Animation.DROP, position: new google.maps.LatLng(this.model.get('lat'), this.model.get('long')), // give the position here });

So I do this this.model.fetch(); Unfortunately model.fetch() only fires the change event if the new data is different from what was previously stored in the model. How can I always trigger a this.render callback when fetch completes, whether it triggers a change event or not? Thanks (in advance) for your help 回答1: You can use the $.ajax success

When the comment link is clicked the modal will appear. The thing is I have to create a bootstrap modal block for each post so i decided it would be easiest to do this in my backbone template. Why isn't this working? Here is my code: app/assets/templates/posts/index.jst.eco <% for post in @posts.models: %> <tbody><td> <%= post.get('content') %> </td></tbody> <tr><td> <a href="#<%= post.get('id') %>">Comment

Here I'm trying to explain some of the concepts I'm learning. It would be great to having some feedback on them. The render function defines the logic for rendering a template. When it is finished, the onRender callback is called. Here I suppose the rendered view has been not attached to the DOM. It is composed by a tagName (the default is div ) that contains the template I attached to it. To explicitly insert that tag into the DOM I

As far as I understand Remove all models from collection Add newly "fetched" models to collection Fires reset event In my case each model draw something on SVG so I should call remove function before removing model from collection. Which event is triggered when model is removed from collection? 回答1: As @Paul noted, there is no predefined event fired before a reset . However, you can provide your own by overriding the reset method on your collection. For example, var SVGCollection = Backbone.Collection
