Question

for some reason I need to use a variable as the selector for events in backbone, but I can’t figure how to do this :

app.views.Selfcare = Backbone.View.extend({
    events: {
        click window.parent.document .close : "closeWindow"
    },
    closeWindow: function() {
        //code
    }
});

I have to use a different scope and I can’t do “click .close” : “closeWindow”.

Thx for your help.

I had a look at Backbone.js’s source code and found out that if your view’s events is a function then the function is called and it’s return value is used as the events object.

This means that your code can be changed like this:

app.views.Selfcare = Backbone.View.extend({
  events: function() {
    var _events = {
      // all "standard" events can be here if you like
    }
    _events["events" + "with variables"] = "closeWindow";
    return _events;

  },
  closeWindow: function() {
    //code
  }
});

THIS is the interesting part of the source code:

if (_.isFunction(events)) events = events.call(this);
