Template bindingObjectiveTemplate binding uses templates to render data to a page. Template bindings are very handy for building nested structures of pages. By default, Knockout is using the popular Jquery.tmpl template engine. With it, you need to download and reference the Jquery.tmpl and jquery frameworks on the installation page. Or you can integrate other template engines (although you need to know knockout
In the first two articles, we experienced basic validation and custom validation of knockout. This article customizes the display location and content of the verification information. Customize where validation information is displayed Typically, the validation information for knockout immediately follows input, and the Validationmessage property allows you to customize the display location of the validat
Use asp.net mvc, bookers, and knockout. js to develop custom menu editing tools (recommended ),
Preface
You can edit the custom menu by using the interface debugging tool, but by submitting the menu for creating json-format data, it is very inconvenient and error-prone. The tool on the Internet is not easy to use, so I wrote one by myself.
Body
Use bootstrap to sort out the page framework. To call the custom menu interface, you must use accesen en and
Knockout. js tries to introduce Microsoft's verified mvvm solution to JS, so it is necessary to learn. Mvvm is designed for interface development to solve rich interactive frequency changes, which is very similar to web development. Production Manager and test supervisor, who can't understand the back-end things and can only point out what the front-end sees, so the changes are very frequent, every change, but with the painful events, re-binding and p

Valueaccessor: The Model property value of the current binding can be obtained by calling Valueaccessor (), and invoking Ko.unwrap (Valueaccessor ()) makes it easier to obtain observable values and normal values;
Allbindings: All property values that are bound to model on this DOM element, such as calling Callbindings.get (' name ') to return the binding's Name property value (no return undefined exists). or call Allbindings.has (' name ') to d

Use Knockout practice 01 in ASP. net mvc to bind a Json object and knockoutjson
This article uses Knockout in ASP. net mvc and uses EF Code First to create a database. Finally, bind the Knockout to a Json object.
Create a domain model.

Resource cleanup and memory managementOptionally, your ViewModel class can have a Dispose function, and if implemented, knockout will call this function whenever the component is destroyed (for example, because the item of the response is removed from the foreach, or if the bind becomes false)You must use Dispose to remove any resources that are not collected by the garbage inside. For example:
The setinterval callback will continue to trigge
the same as that of linq, Which is concise.Now, let's look at the code in my webapi. Is there only two lines of code for each method and complicated operations have been implemented.Just because of my framework, I was freed from the background and had more time and energy to study the front-end.
III,This function can be completed with a few simple codes. Let's take a look at the implementation results.

Today, there is a problem in the project, and using the knockout monitoring text box is not able to get the time that was selected for the DatePicker control.

Add, remove, and modify bindings in Knockout JS.
Knockuot JS seems to have only considered how to bind (ko. applyBindings (), but has not considered how to remove the binding. When the DOM content is modified and needs to be re-bound, it seems powerless.

A similar error is often encountered in the use of knockout development: uncaught referenceerror:unable to process binding "text:function () {return title}". When the model is relatively simple, we can easily find problems, generally as long as the correct error in the title in the $root, $parent, $data the three objects. If you use the knockout component, the problem becomes more complicated. For example:
Knockout should be the most widely used MVVM framework in the blogosphere, but rarely introduces the implementation of its monitoring array. Recently tried to upgrade the Avalon of the array of surveillance, decided to study it a good, see if there is no reference to the place.
