启用select控件的一些选项，根据对象数组的某些属性使用knockout禁用其余选项

var options = [
  { id: 1, name: 'Option 1', disabled: false },
  { id: 2, name: 'Option 2', disabled: true },
  { id: 3, name: 'Option 3', disabled: false }
];

var selectedOption = ko.observable();

<select data-bind="options: options,
                   optionsText: 'name',
                   optionsValue: 'id',
                   value: selectedOption,
                   foreach: options">
  <option data-bind="text: name, value: id, disable: disabled"></option>
</select>

function ViewModel() {
  this.options = options;
  this.selectedOption = selectedOption;
}

ko.applyBindings(new ViewModel());
