在ribs.js中，如何捕获除纯“更改”事件以外的所有事件？

Question

When I bind to the "all" event and some property changes, i receive 2 events: the "change:property" event and the plain "change" event. Since I always catch the property specific event , I dont need the plain one. I cannot bind to all "change:*" individually because i dont know beforehand all the properties that might get added to the model. So is there any way to stay with model.bind("all", ...) and somehow get rid of the "change" event?

PS I know I can filter the name in the handler, I am asking if there is a more standard way of filtering or declaring events in models, that I dont know of.

Answer 1

Unfortunately the only way is to manually add a filter

ModelA = Backbone.Model.extend({
  initialize: function() {
    this.bind('all', this.onChange, this);
  },

  onChange: function() {
    //apply your filter
  }
});

can't you just use the change event and then check what attributes have changed by accessing the changedAttributes method (during the propagation of change event it will return you a hash of only the attributes that have changed during this change event - see more here ). I believe this is the cleanest way to handle that - at least based on the details provided.
