I'm trying to create a reusable checkbox component with Angular 8, using the CheckboxControlValueAccessor. I can't understand what should I write in the "writeValue" and "onChange" functions, so that the value of the checkbox will get "checked" on each click.
Already manage to create reusable input component with ControlValueAccessor and Validator.

I want to create a fully customized Vue.js application and what I want is to save Vue.js component in database and load the corresponding Vue.js component based on the user.
That will make the app fully customized and I can customize component for each user individually.
Is there any library can compile Vue.js 3 component (composition API) on the fly?
Is it possible in VueJS to have a default click event on a custom component?
E.g. we have built a component called editable. Now on click, we always want it to fire the same function, no matter where we call that component.
<editable #click="doSomething" ...></editable>
Can I define that somewhere in the JS side?
In case of custom component, you need to bind to native event:
<editable #click.native="doSomething" ...></editable>
For documentation, refer to Vue.js docs here.
I have a form built with Vue with a hierarchy of components using v-model to bind the data to the model.
Now I want to fill the form programmatically. If I just update the model (data) of the top component, it has no effect on the child components since this only changes their props.
Here's an example:
https://jsfiddle.net/eywraw8t/411545/
When you click the 'Set to 2018-Oct' button, the model on the myApp is updated, but not the model of the <mydate> component.
Is there a way to achieve filling the form without adding watchers to value props (which the official guide doesn't suggest) on all components in the hierarchy?
I have datatable which is created through columns and items array.
I want to create one anchor link in vuejs which will call component method on click. Also in the items array may be contains html which i want to bind to vuejs events.
Thanks.
I have a modal component with textarea which I use to edit data that's in my main instance. So the idea is when I open the modal component, the textarea should be showing current data value from the main instance, this can be done by passing data as prop to the modal component. But since it's prop, vue doesn't allow me to edit it in textarea. And if I use v-model for the textarea, how do I get the original data value the moment my modal popup?
Back in 1.x, I just need to add "two-way: true", but this approach depreciated in 2.0.
pass myProp object as a prop and on the text area you pass v-model="myProp.cellModel"
