Question

Is it possible to create model and view in Backbone.js with parameters ?
I try simple like

    var TestModel = Backbone.Model.extend( {
        initialize: function(test){
        this.set('test',test);
        alert("test");
    }
});

but I got message this.set is not a function.

There’s a syntax error in your example code, but that should work just fine. You also need to account for the model’s attributes as the first parameter and reference a generic options object as the second parameter (see the code here http://backbonejs.org/docs/backbone.html#section-28 )

From your sample code, though, it looks like you’re just trying to pass data to the model, which is handled for you automatically.

var TestModel = Backbone.Model.extend({});

var t = new TestModel({foo: "bar"});

console.log(t.get("foo"));

Or if you’re trying to get some options, you can do this:

var TestModel = Backbone.Model.extend({
  initialize: function(attrs, options){
    console.log(options.foo);
  }
});

var t = new TestModel(null, {
  foo: "bar"
});
