knockout.js - Updating view model from object not working -

-

i want able observe object inside view model. have simple example doesn't work expected, can see problem?

using knockout 1.1.1, have 2 inputs such:

<form data-bind="submit: save">     <input type="text" data-bind="value: deckname" />     <input type="text" data-bind="value: deck().name" />     <button type="submit">go</button> </form>

when page loads, inputs default values, on submitting form viewmodel.deck().name not updated viewmodel.deckname is.

<script type="text/javascript">     var initialdata = {"name":"test"};      var viewmodel = {         deck: ko.observable(initialdata),         deckname: initialdata.name,         save: function() {             ko.utils.postjson(location.href, { deck: this.deck, deckname: this.deckname });         }     };     ko.applybindings(viewmodel); </script>

on form post, deck still send "test" no matter input whilst deckname corresponding input value.

what want able observe object viewmodel.deck , bind properties inputs, properties don't updated.

there several problems have provided.

  1. you've set 1 time value setter second input since deck().name static value (as opposed ko.observable or ko.observablearray). (to prove add viewmodel.deck({"name":"updated test"}); end of script after ko.applybindings(viewmodel);)
  2. deckname 1 way binding - it's written during initial applybindings , viewmodel updated changes made user or scripts <input>. however, if make programmatic changes viewmodel input field not updated match. you'll want take @ last part of knockout.js' value binding documentation.

a improved version:

<form data-bind="submit: save">     <input type="text" data-bind="value: deckname" />     <input type="text" data-bind="value: deck().name" />     <button type="submit">go</button> </form> <script type="text/javascript">     var initialdata = {"name":"test"};      var viewmodel = {         deck: ko.observable(initialdata),         // set 2 way binding         deckname: ko.observable(initialdata.name),         // set 1 time value setter         save: function() {             ko.utils.postjson(location.href, ko.tojson(this));             // when save model post *it* back, rather             // serializing hand.         }     };     ko.applybindings(viewmodel);     viewmodel.deck({"name":"updated test"}); </script>

an alternate version using fromjs:

<form data-bind="submit: save">     <input type="text" data-bind="value: name" />     <button type="submit">go</button> </form> <script type="text/javascript">     var initialdata = {"name":"test"};      var viewmodel = ko.mapping.fromjs(initialdata);     viewmodel.save = function() {         ko.utils.postjson(location.href, ko.tojson(this));         // when save model post *it* back, rather         // serializing hand.     }     ko.applybindings(viewmodel); </script>

you'll want @ knockout's fromjson , fromjs funcitons (implemented in mapping plugin).
