Replacing item in observableArray

Question

I\'m trying to replace all of the contents of an item in an observableArray with new content.

var oldLocation = ko.utils.arrayFirst(self.locations()         


        

Answer 1

I'm not aware of a replace method in JavaScript for arrays, or in Knockout. Am I missing something?

If you want to use your second method, then you need to access locations as an observable:

self.locations()[self.locations.indexOf(location)] = new fizi.ko.models.location(value);
self.locations.valueHasMutated();

though you don't when using indexOf, as there is a Knockout version of that for observable arrays.
