我试图在下拉列表中显示一个可观察的数组,当用户选择该选项时,我想呈现该视图模型的属性.看起来很简单.我提供了代码和Fiddle的链接.

HTML:

<select data-bind="options: oCountries, 
                   optionsText: 'name', 
                   optionsValue: 'isocode', 
                   value: selectedCountry">
</select>

Controlled by <span data-bind="value: selectedCountry.isocode"></span>

JS:

var countries = [{
    "name": "Afghanistan",
    "isocode": "AF",
    "language": "English",
    "crmdatacontroller": "CRM India"
}, {
    "name": "Aland Islands",
    "isocode": "AX",
    "language": "Finnish",
    "crmdatacontroller": "CRM Finland"
}]

var viewModel = {
    oCountries: ko.observableArray(countries),
    selectedCountry: ko.observableArray(['AX'])
};

ko.applyBindings(viewModel);
