index.htmlを

<label for="language" class="col-xs-12 col-sm-3 control-label no-padding-left no-padding-right"></span> 
     Language selection:</label> 
    <div class="col-sm-9"> 
     <select id="language" 
       data-bind="options: possibleLanguage, optionsText: 'text', optionsValue: 'key', value: selectedLanguage" 
       class="col-xs-12 col-sm-5"/> 
     <span class="text-muted hidden-xs col-sm-12 no-padding-left">Select the language used to display the interaction.</span> 
    </div> 

のために、私のindex.jsにこの選択を持っている私tokenValue observableこの1つは作品とhtml

<label for="token" class="col-xs-12 col-sm-3 control-label no-padding-left no-padding-right"></span> 
       Token:</label> 
      <div class="col-sm-9"> 
       <input id="token" type="text" data-bind="value: tokenValue, valueUpdate: 'keyup'" 
         class="col-xs-12 col-sm-5 margin-top-5"/> 
       <span class="text-muted hidden-xs col-sm-12 no-padding-left">Insert the token used for authentication.</span> 
      </div> 

に次のように設定されている私は、HTMLデータ・バインディング内event:{ change: languageHasChanged}を追加しましたので、私は、私は何か他のものを選択するとselectedLanguageの値が設定されていないことを99％に確信しているとオブザーバブルの値を追加するはずのトースターが現れたが空だった。

良い古いjQueryを使用して回避策を見つけることができますが、それらの購読を手助けすることができれば幸いです！

ありがとうございます！
