When iterating through arrays and collections, it is common to get the index of an element, and this experience uses knockout to get an index of 2 methods. Suppose there is a model like this:namespace useindex.models{ publicclass Student { publicint getset;} Public string Get Set ; } }}In HomeController, a collection of student is simulated, the collection of the Name property is projected, and the last JSON is returned to

This article mainly introduces the creation method of Knockout custom binding. For more information, see Overview In addition to the built-in binding types (such as value and text) of KO listed in the previous article, you can also create custom binding. Register Your binding handler ko.bindingHandlers.yourBindingName = { init: function(element, valueAccessor, allBindings, viewModel, bindingContext) { // This will be called when the binding is

For example, the database is couchdb and the stored data is in JSON format. The simpler the JSON data to be stored, the clearer the better.

As a result, the format conversion function, two-way, storage to bind, bind to storage. The conversion function is as follows:Function kojsontocouchjson (ARG, stringkey

What is Knockout.js? Knockout is a very good JavaScript library that can help you create a rich text user interface with good display and editing capabilities using only a clean and neat underlying data model. Any time your local UI content needs to be updated automatically (for example, depending on user behavior changes or external data source changes), KO can be very simple to help you achieve, and very easy to maintain. First, the main class dia

It is mainly used for high-speed cache acceleration services and is generally deployed on the network edge. Different acceleration objects are divided into client acceleration and server acceleration. The client acceleration cache is deployed at the network exit and the frequently accessed content is cached locally to increase the response speed and save bandwidth. Server ac

Knockout can be used to obtain array element indexes. It is implemented in MVC. knockoutmvc When traversing arrays and sets, you usually need to obtain the element index. In this article, you can use two methods to obtain the index using Knockout. Suppose there is a model like this: namespace UseIndex.Models{ public class Student { public int Id { get; set; } public string Name { get

It is not possible to use functions to pass parameters directly in knockout, which will cause the function to be called at initialization time, for example:will cause the function to be called when it is initialized, clicking on the event Changeeditor () function, which clearly violates the original intention. There are 2 ways to implement parameter delivery:1. Method One: Use function wrappingClick the event response function and set a layer, call th
