阅读更多关于 Map JSON data to Knockout observableArray with specific view model type

Is there a way to map a JSON data object to an observable array and then in turn have each item of the observable array be initialized into a specific type of view model? I've looked at all of knockout's documentation along with the knockout and mapping examples here and I can't find any answer that works for what I'm after. So, I have the following JSON data: var data = { state : { name : 'SD', cities : [{ name : 'Sioux Falls', streets : [{ number : 1 }, { number : 3 }] }, { name : 'Rapid City', streets : [{ number : 2 }, { number : 4 }] }] } }; And I have the following view models: var

KnockOutJS - Multiple ViewModels in a single View

阅读更多关于 KnockOutJS - Multiple ViewModels in a single View

I'm thinking that my application is getting quite large now, too large to handle each View with a single ViewModel. So I'm wondering how difficult it would be to create multiple ViewModels and load them all into a single View. With a note that I also need to be able to pass X ViewModel data into Y ViewModel data so the individual ViewModels need to be able to communicate with each other or at least be aware of each other. For instance I have a <select> drop down, that select drop down has a selected state which allows me to pass the ID of the selected item in the <select> to another Ajax call

问题 We are using knockout and the knockout mapping plugin to facilitate databinding in our jQTouch web application. The reason we use the mapping plugin, is to be able to use knockout without the need to define/change viewmodels manually in javascript. The mapping plugin works great when you have an initial load of data from the server/client side database. The problem we are having is that we have some screens/views which have a form in which it is possible that there isn't any initial data.
