kandi X-RAY | knockout Summary
Knockout is a JavaScript MVVM (a modern variant of MVC) library that makes it easier to create rich, desktop-like user interfaces with JavaScript and HTML. It uses observers to make your UI automatically stay in sync with an underlying data model, along with a powerful and extensible set of declarative bindings to enable productive development.

QUESTION
I have a button that uploads the excel file.

Answered 2022-Apr-01 at 01:14QUESTION
I tried to run JSON.parse($("input").attr("data-bind")) but it throws an error.
Is there something similar in the Knockout library that I could somehow use?
I would like to construct an object of all the bindings relevant to an element, and combine it with bindings relevant to parent elements.
Would anyone happen to know what I can do to achieve this?
Your help is greatly appreciated.
...ANSWER
Answered 2022-Mar-20 at 09:20Knockout's binding strings are not valid JSON, so that's why you can't parse it as such.
The default parsing logic is exposed though. You can access it through a bindingProvider instance (have a look at the source to see all available methods).
Here's a simple proof of concept you can start with:

QUESTION
We are using Knockout.js (v3.5.0) and its TypeScript definitions. They worked OK until TypeScript 4.6.2. However the problem seems to be "deeper" than in the definitions file. It seems that there was some change in TypeScript in handling a boolean type. So rather than tagging this question as Knockout.js problem, I created small example of code inspired by the Knockout d.ts that illustrates the problem:
...ANSWER
Answered 2022-Mar-08 at 13:13According to the user who has responded to the Github issue (https://github.com/microsoft/TypeScript/issues/48150) the Typescript 4.6 compilation error is expected:
I believe this is a correct error which was not handled properly in old versions. The generic parameter T is invariant as it is used in both a covariant position () => T and a contravariant position (value: T) => any.
which is indeed true. Since user helped solve the problem, for sake of completeness I will try to rephrase and summarize his comments here.
The first proposed solution solves the problem only partially:
