So, I am learning out backbone.js and are currently iterating over some models in a view with the below example. The first snippet works, when the other underscore.js-based one doesn't. Why?
// 1: Working
this.collection.each(function(model){ console.log(model.get("description")); });
// 2: Not working
_.each(this.collection, function(model){ console.log(model.get("description")); });
What am I doing wrong, as I can't see it by myself?
this.collection is an instance while this.collection.each is a method that iterates the proper object under the covers which is the .models property of a collection instance.
With this said you can try:
_.each(this.collection.models, function(model){ console.log(model.get("description")); });
Which is completely pointless as this.collection.each is a function that does similar to:
function(){
return _.each.apply( _, [this.models].concat( [].slice.call( arguments ) ) );
}
So you might as well use this.collection.each ;P
Also, you could try...
_.each(this.collection.models, function(model){
console.log(model.get("description"));
});
