MVC と KnockOut/jQuery のスキルを磨くために、カート スタイルのアプリを作成しています。
部屋のタイプ、占有率などを選択できる場所で機能しており、合計値が更新されます。
私はこれまでに到達した場所の jsFiddle をここに持っています: http://jsfiddle.net/mtait/cGGvA/1/
3つのスライダーを追加したい:
<label for="slider-1">Extra Towels:</label>
<input type="range" name="slider-1" id="slider-1" min="0" max="100" value="50" data-popup-enabled="true">
<label for="slider-2">Morning Papers:</label>
<input type="range" name="slider-2" id="slider-2" min="0" max="100" value="50" data-show-value="true">
<label for="slider-3">Packed Lunch:</label>
<input type="range" name="slider-3" id="slider-3" min="0" max="100" value="50" data-show-value="true" data-popup-enabled="true">
また、いくつかの Javascript を追加して、各スライダー項目のコストをスライダーに関連付けます。
<script>
var slider1cost = 10;
var slider2cost = 40;
var slider3cost = 65;
</script>
たとえば、誰かが予備のタオル 2 枚、朝刊 1 枚、お弁当 0 を選択した場合、今と同じようにTotal Value
部屋代を計算して、さらに 60 ポンド (2 x 10 + 1 x 40 )。
以下の KnockOut コードは、部屋のみに接続されています。スライダーの値をそのコードに追加するにはどうすればよいですか。
私がこれまでに持っているHTML全体は次のとおりです。

<tbody data-bind='foreach: lines'>
