knockout-3.0

问题 I updated a web app to Bootstrap 3 and Knockout 3 and consequently lost the built in typeahead that was in Bootstrap 2.

问题 I'm faced a problem that my computed observable stops triggering after some sequence of dependency changes.

Here is a sample: https://jsfiddle.net/sgs218w0/1/ var viewModel = new function(){ var self = this; self.trigger = ko.observable(true); self.fire = function(){ self.trigger(! self

问题 I have a change occurring to an array. I am using Sanderson's latest array subscription method to catch the add/delete change. In this subscription is where I intend to bundle and send my request over the wire. If the request fails for any reason I want to be able to cancel any possible changes to the collection. I have verified that this subscription is hit before the change propagates so I assume there would be a way to say "STOP DON'T DO IT" however I can't figure out how. As my example...

I was duplicating content in the background and generating invalid HTML

问题 I have an array of objects for which I am showing their properties. How can add an individual edit functionality to them? Lets say it to be an edit button for each one of the elements of the list. I want to show input fields instead of text fields when the object is in edit mode, for this I am using the visible binding. So I need a Boolean observable for each of them.
