Is there any way to convert observable to observable array?
I am asking this because there is one function in my code which expect observable array because the function uses ko.utils.arrayForEach
I have try to google but couldnt find anything.
Update
i checked what i am passing using var test = isObservable(item). its not observable that i am passing because i get false in variable test Its normal array.
So i want to convert array to observable array
This question doesn't make a ton of sense to me, but here goes -
To convert an array to an observable array, do this -
var normalArray = ['1', '2']
normalArray = ko.observableArray(normalArray);
// normalArray is now an observableArray
you can use convert normal array to observable array usingko.observableArray()
var SimpleListModel = function(items) {
this.items = ko.observableArray(items);
this.itemToAdd = ko.observable("");
this.addItem = function() {
if (this.itemToAdd() != "") {
this.items.push(this.itemToAdd()); // Adds the item. Writing to the "items" observableArray causes any associated UI to update.
this.itemToAdd(""); // Clears the text box, because it's bound to the "itemToAdd" observable
}
}.bind(this); // Ensure that "this" is always this view model
};
ko.applyBindings(new SimpleListModel(["Alpha", "Beta", "Gamma"]));
