In Knockout how do you go about nesting custom components when using an html binding?

I'm a bit new to knockout. I'm trying to get a custom component to dynamically load another custom component. I have a variable called location_board that contains html and that html has a custom component in it. . When I use the data-bind="html: location_board" it put the line for the in the dom but it doesn't run the custom component to fill out that node. Note: If I add the npc-widget directly to the template it works. It just doesn't work when it is added though the html binding. From my research I think this means I need to applyBindings on it? I'm not sure how to go about that in this situation though.
Any help is apricated.
Here is my full code for the custom component.
import {Database} from './database.js'
let database = new Database();
import {ResourceManager} from "./resource-manager.js";
let resourceManager = new ResourceManager();
let locationRegister = {
fog_forest: {
name: "The Ghostly Woodland",
image: "url('img/foggy_forest.jpeg')",
description: `
Place holder
`,
location_board: `
<npc-widget id="john-npc" params="id: 1, tree: 'shopkeep', speed: 50"></npc-widget>
<div>In</div>
`
}
};
ko.components.register('location-widget', {
viewModel: function (params) {
let self = this;
self.function = function () {
console.log("Functions!")
}
for(let k in locationRegister[params.id]) {
console.log(k)
this[k] = locationRegister[params.id][k];
}
console.log(this.name)
//return { controlsDescendantBindings: true };
},
template:
`
<div class="row">
<div class="col-lg-12">
<h2 id="title" class="tm-welcome-text" data-bind="html: name"></h2>
</div>
</div>
<div class="row">
<div class="col-lg-12">
<div data-bind="style: { 'background-image': image}" class="location-picture mx-auto d-block">
</div>
</div>
</div>
<div class="row">
<div class="col-lg-12">
<div class="location-description mx-auto d-block" data-bind="html: description"></div>
</div>
</div>
</div>
<hr>
<div class="row">
<div class="col-lg-12">
<div id="location_board" data-bind="html: location_board">
</div>
</div>
</div>
`
});

How to hide slotted element before rendering the vue template in vueJs 3?

See this images
i dont want to display here those elements
See the Below code sample
sample.blade.php
<create-form id= "create_form" title="Sample Form" >
<div class="col-md-6">
<label class="form-label" for="multicol-username">Username</label>
<input type="text" id="multicol-username" class="form-control" placeholder="john.doe" name="ma_user_id" data-type="varchar" required>
</div>
<div class="col-md-6">
<label class="form-label" for="multicol-email">Email</label>
<div class="input-group input-group-merge">
<input type="text" id="multicol-email" class="form-control" placeholder="john.doe" aria-label="john.doe" aria-describedby="multicol-email2" name="password" data-editmode="false" data-editname="email">
<span class="input-group-text" id="multicol-email2">#example.com</span>
</div>
</div>
</create-form>
createForm.vue

</div>
</template>
<script>
export default {

app.js
require('./bootstrap')
import { createApp } from 'vue'

const app = createApp({})
app.component('create-form', createForm);
app.mount('#app')

It sounds like you want the template that's rendered by the php backend to not be visible until vue is able to handle it, though I'm not 100% sure that's the case.
If that is the case, you could use the v-cloak directive
This directive is only needed in no-build-step setups.
When using in-DOM templates, there can be a "flash of un-compiled templates": the user may see raw mustache tags until the mounted component replaces them with rendered content.
v-cloak will remain on the element until the associated component instance is mounted. Combined with CSS rules such as [v-cloak] { display: none }, it can be used to hide the raw templates until the component is ready.
<create-form id="create_form" title="Sample Form" v-cloak>
...
<style>
[v-cloak] { display: none }
</style>

Property or method "sendResetMail" is not defined on the instance but referenced during render

I'm relatively new to Vue and super stuck with this error message when I try to make this reset email modal work in my Vue project:
Property or method "sendResetMail" is not defined on the instance but
referenced during render. Make sure that this property is reactive,
either in the data option, or for class-based components, by
initializing the property.
I have no idea what I need to do to make this work. I followed the Vue documentation and declared resetEmail in the data option.
ForgotPassword.vue:
<template>
<section>
<a #click="isComponentModalActive = true">
Forgot Password?
</a>
<b-modal :active.sync="isComponentModalActive" has-modal-card>
<modal-form v-bind="resetEmail"></modal-form>
</b-modal>
</section>
</template>
<script>
import firebase from 'firebase/app'
import 'firebase/auth'
import 'firebase/firestore'
const ModalForm = {
props: ['resetEmail'],
template: `
<form #submit.prevent="sendResetMail">
<div class="modal-card" style="width: auto">
<header class="modal-card-head">
<p class="modal-card-title">Forgot password?</p>
</header>
<section class="modal-card-body">
<b-field label="Email">
<b-input
type="email"
:value="resetEmail"
placeholder="Your email"
required>
</b-input>
</b-field>
</section>
<footer class="modal-card-foot">
<button class="button" type="button" #click="$parent.close()">Close</button>
<button class="button is-primary">Reset</button>
</footer>
</div>
</form>
`
}
export default {
components: {
ModalForm
},
data () {
return {
isComponentModalActive: false,
resetEmail: '',
feedback: null
}
},
methods: {
sendResetMail () {
var auth = firebase.auth()
var emailAddress = this.resetEmail
auth.sendPasswordResetEmail(emailAddress).then(function () {
// Email sent.
console.log('email send')
}).catch(function (error) {
// An error happened.
this.feedback = error.message
console.log(error.message)
})
}
}
}
</script>
This is the file where I use the ForgotPassword.vue component,

firebase

.signInWithEmailAndPassword(this.email, this.password)
.then(cred => {
this.$router.push({

})
})
.catch(err => {
this.feedback = err.message

I would be very grateful if someone can explain to me what I'm missing :)

You are referencing
<form #submit.prevent="sendResetMail">
inside your ModalForm component.
The problem is that this template is going to look for the method sendResetMail on that ModalForm component template when it gets rendered since you the code is referencing it. However this sendResetMail method is not directly associated on that.
You can consider using a mix-in if you need to use the sendResetMail in many places , or maybe just move that method directly to the same component "ModalForm" that is referencing it.
You can also look into for example eventBus to trigger the method by emitting an event.
The simplest option if you only need to call it from the MOdalForm component is to just move the sendResetMail direcly to that component. I believe that would probably fix your issue.

Vue.js: How the child components mutate the parent's state?

In vuejs.org, there said:
The two-way binding will sync the change of child’s msg property back to the parent’s parentMsg property. (Here is the link.)
But I'm confused that how could I change child's property so that this change can be synced back to its parent?
router
// Define rule of router.
router.map({
'/categories': {
// The List.vue
component: CategoryList,
subRoutes: {
// ... some rules ...
'/add': {
// The DetailAdd.vue
component: CategoryDetailAdd
}
}
}
});
List.vue (the parent)
<template>
<tab v-bind:tabs="tabs" :active="active"></tab>
<div class="col-lg-12">
<router-view :categories="categories"></router-view>
</div>
</template>
<script>
var Tab = require('../common/Tab.vue');
export default{
components:{
tab: Tab
},
data() {
return {
categories: [],
tabs: [],
active: '1'
};
},
ready() {
this.$http.get('/categories').then((response) => {
// success
this.$set('categories', response.data.categories);
this.$set('tabs', response.data.tabs);
this.$set('active', response.data.active);
}, (response) => {
// error
})
}
}
</script>
DetailAdd.vue (the child)
<template>
<form class="form-horizontal" method="post" action="/categories/add">
<div class="form-group">
<label for="name" class="col-md-2 control-label">name</label>
<div class="col-md-10">
<input id="name" type="text" class="form-control" name="name" value="" />
</div>
</div>
<div class="form-group">
<label for="category_id" class="col-md-2 control-label">superiror</label>
<formselect></formselect>
</div>
<div class="form-group">
<label for="sort_order" class="col-md-2 control-label">sort</label>
<div class="col-md-10">
<input id="name" type="text" class="form-control" name="sort_order" value="" />
</div>
</div>
<formbutton></formbutton>
</form>
</template>
<script>
var FormSelect = require('../common/FormSelect.vue');
var FormButton = require('../common/FormButton.vue');
export default{
components: {
formselect: FormSelect,
formbutton: FormButton
}
}
$(function() {
$('.nav-tabs').on('ready', function() {
$('.nav-tabs li').attr('class', '');
$('.nav-tabs li:last').attr('class', 'active');
});
});
</script>
I just want to mutate the active property in parent (List.vue), how to achieve this?
Thank all of you!

The two-way binding works as you might think it does: when you change a property in the parent, it gets changed in the children, and vice versa. Take a look at this as an example: https://jsfiddle.net/u0mmcyhk/1/, the children is able to change the state of the parent. If you remove .sync from the parent template, it stops working.
Having said that, .sync will be deprecated on 2.0, in favour of communication (broadcast, dispatch) or some state management like vuex.

Why is extending an extended view not working in ember.js?

I am trying to create a modal view and have a base class that all modals need and then extending it for more specific functionality.
PlanSource.Modal = Ember.View.extend({
isShowing: false,
hide: function() {
this.set("isShowing", false);
},
close: function() {
this.set("isShowing", false);
},
show: function() {
this.set("isShowing", true);
}
});
PlanSource.AddJobModal = PlanSource.Modal.extend({
templateName: "modals/add_job",
createJob: function() {
var container = $("#new-job-name"),
name = container.val();
if (!name || name == "") return;
var job = PlanSource.Job.createRecord({
"name": name
});
job.save();
container.val("");
this.send("hide");
}
});
I render it with
{{view PlanSource.AddJobModal}}
And have the view template
<a class="button button-green" {{action show target=view}}>+ Add Job</a>
{{#if view.isShowing}}
<div class="modal-wrapper">
<div class="overlay"></div>
<div class="dialog box box-border">
<div class="header">
<p class="title">Enter a job name.</p>
</div>
<div class="body">
<p>Enter a name for your new job.</p>
<input type="text" id="new-job-name" placeholder="Job name">
</div>
<div class="footer">
<div class="buttons">
<a class="button button-blue" {{action createJob target=view}} >Create</a>
<a class="button" {{action close target=view}}>No</a>
</div>
</div>
</div>
</div>
{{/if}}
The problem is that when I click the button on the modal dialog, it gives me an "action createJob" can not be found. Am I extending the objects incorrectly because it works if I put the createJob in the base Modal class.
Fixed
There was an issue somewhere else in my code. The name got copied and so it was redefining it and making the method not exist.
