我想获得所选的选项对象
<select data-bind="options: availableCountries,value: selectedCountry,event: { select: onSelect}"></select>
<script type="text/javascript">
// Constructor for an object with two properties
var Country = function(name,population) {
this.countryName = name;
this.countryPopulation = population;
};
var viewmodel = {
availableCountries : ko.observableArray([
new Country("UK",65000000),new Country("USA",320000000),new Country("Sweden",29000000)
]),selectedCountry : ko.observable(),// Nothing selected by default
onSelect: function(){
console.log(viewmodel.selectedCountry)
// it is showing just an country name and what i what is whole object
// e.g. { "UK",65000000 } // that is selected option in selected Box
}
};
</script>
