I have the following javascript object which I use as an enum.
Object {Group1: 0, Group2: 1, Group3: 2, Group4: 3, Group5: 4}
Id like to be able to use it to create check boxes or drop downs using knockout templates basicly i need these values to be observable.
Ive tried adding the object to an observable array but it doesnt work. can any one help?
You can use a computed observable for that.
function ViewModel(){
var obj = {Group1: 0, Group2: 1, Group3: 2, Group4: 3, Group5: 4}; // Your object
this.data = ko.computed(function(){
// works on modern browsers (keys/map), old ones would need
// a shim or for in loop
return Object.keys(obj).map(function(elem){
return {val:elem+" -> "+obj[elem]};
});
});
}
ko.applyBindings(new ViewModel());
