I'm using backbone.js along with jquery and underscore.js
Here's some of my code (it doesn't do anything yet). The strange thing is that upon hitting the url /#users there isn't an error. The only time the error happens is when I then click to go to a different hash and then click back to go to /#users. Here's part of my code, with the line that receives the error toward the end Users = new Users(); the error says Users is not a constructor:
var User = Backbone.Model.extend({
url: function(){return 'api/user/id/' + this.id;}
});
var Users = Backbone.Collection.extend({
model: User,
url: function(){return 'api/users';},
initialize: function() {
}
});
var UsersView = Backbone.View.extend({
initialize: function() {
this.users = this.options.users;
this.render();
},
render: function() {
_(this.users).each(function(){
// $('#app').append('here');
});
var template = _.template($('#usersTemplate').text());
$(this.el).html(template({users: this.users}));
$('#app').html(this.el);
}
});
var UserView = Backbone.View.extend({
initialize: function() {
this.user = this.options.user;
this.render();
},
render: function() {
var template = _.template(hello {{user.name}});
$(this.el).html(template({user: this.user.toJSON()}));
$('#app').html(this.el);
}
});
var Controller = Backbone.Controller.extend({
routes: {
'dashboard' : 'dashboard',
'users' : 'showusers'
},
showuser: function(id) {
UserList.fetch({
success: function(){
new UserView({user: User});
},
error: function(){
alert('an error of sorts');
}
});
},
showusers: function() {
Users = new Users();
Users.fetch({
success: function(Users) {
new UsersView({users: Users});
},
error: function() {
}
});
},
dashboard: function() {
Users = new Users;
Users.fetch({
success: function() {
new UsersView({users: Users});
},
error: function() {
}
});
}
});
$(document).ready(function(){
var ApplicationController = new Controller;
Backbone.history.start();
});
the accompanying html if you're curious:
