knockout.js - KO.js howto set default view when using view constructor -

-

i'm (new ko!) playing view constructor offered ryan niemayer here: how structure knockoutjs application, , i'm trying set default view show on load…

for example in #3, can use constructor function like…

and here fork attempting set default:

// (templates defined in fiddle) var view = function(title, templatename, data) {    this.title = title;    this.templatename = templatename;    this.data = data;  };  var definedviews = ko.observablearray([     new view("one", "onetmpl", new submodela()),     new view("two", "twotmpl", new submodelb()) ]);  var viewmodel = {     views: definedviews,     defaultview: 0,     selectedview: ko.observable( definedviews[0] ) };  ko.applybindings(viewmodel);

index.html:

    <!-- ko with: selectedview -->     <div data-bind="template: { name: templatename, data: data }"></div>     <!-- /ko -->

http://jsfiddle.net/memelab/wvvym/2/

on load, selectedview undefined, when i've clicked select, contains object expected…

i've tried refactoring viewmodel function, trying feed parameters html declaration, , bunch of random guesswork not coherent enough summarise here…

any suggestions? tia!

actually you're missing () 

var viewmodel = {     views: definedviews,     defaultview: 0,     selectedview: ko.observable( definedviews()[0] ) };

here working fiddle: http://jsfiddle.net/zahc9/

-
i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
