Laravel Livewire: Bootstrap Select-Picker unable to render

I want to load categories and multiple sub categories according to all the categories that are selected, inside a multi-step form at step 4, but I am not able to select multiple categories using bootstrap selectpicker (multiple selects) library inside livewire component. The issue with using Bootstrap-Select with Livewire is that both of these libraries use JavaScript to update the page dynamically, which is probably causing conflicts. If I try accessing the same without livewire, it works perfectly fine, but with livewire I am unable to render it.
form.blade
#section('content')
<livewire:multi-step-form />
#endsection
#push('before-styles')
<link rel="stylesheet prefetch" href="https://cdnjs.cloudflare.com/ajax/libs/bootstrap-select/1.13.1/css/bootstrap-select.css" />
#endpush
#push('before-scripts')
<script rel="javascript prefetch" src="https://stackpath.bootstrapcdn.com/bootstrap/4.1.1/js/bootstrap.bundle.min.js"></script>
<script rel="javascript prefetch" src="https://cdnjs.cloudflare.com/ajax/libs/bootstrap-select/1.13.18/js/bootstrap-select.min.js" integrity="sha512-yDlE7vpGDP7o2eftkCiPZ+yuUyEcaBwoJoIhdXv71KZWugFqEphIS3PU60lEkFaz8RxaVsMpSvQxMBaKVwA5xg==" crossorigin="anonymous" referrerpolicy="no-referrer"></script>
#endpush
multi-step-form.blade
<select wire:model="categories" name="categories[]" class="selectpicker form-control" multiple data-live-search="true" required id="categories" title="{{ trans('select category') }}">
#foreach($categories as $category)
<option value="{{$category->id}}" {{ (collect(old('categories'))->contains($category->id)) ? 'selected' : '' }}>
{{$category->category}}
</option>
#endforeach
</select>
Some Failed Attempts
Inside livewire component
Attempt 1
<script>
document.addEventListener('livewire:load', function () {
$('.selectpicker').selectpicker();
});
</script>
This works well but only once, i.e. at the start when livewire was loaded. This doesn't work, after the livewire component is updated by some input. So I added a code right below it:
Attempt 2
<script>
document.addEventListener('livewire:load', function () {
$('.selectpicker').selectpicker();
$('.selectpicker').selectpicker('render');
});
</script>
This didn't work too. Some few articles had render separated in updated script so I did that too.
Attempt 3
<script>
document.addEventListener('livewire:load', function () {
$('.selectpicker').selectpicker();
});
document.addEventListener('livewire:updated', function () {
$('.selectpicker').selectpicker('render');
});
</script>
Unfortunately this didn't work either.
I have tried adding the same scripts to my app.js too later, but am not sure where am I going wrong, and how can I make this working.
Attempt 4
Kept the scripts as is, and added wire:ignore in parent div
<div wire:ignore class="form-group">
<select wire:model="categories" name="categories[]" class="selectpicker form-control" multiple data-live-search="true" required id="categories" title="{{ trans('select category') }}">
#foreach($categories as $category)
<option value="{{$category->id}}" {{ (collect(old('categories'))->contains($category->id)) ? 'selected' : '' }}>
{{$category->category}}
</option>
#endforeach
</select>
</div>
As suggested in livewire/livewire/issues/45, but this didn't work as well.

Passing variable form blade template to vue component

I have a form in blade template. iF I submit the form I would like to pass id variable to vue component. How can I do it. Please help. Below my code.
<table>
#foreach($zam as $z)
<tr>
<td>{{$z->id}}</td>
<td>{{$z->name}}</td>
<td>{{$z->status}}</td>
<td>{{$z->getUser->name}}</td>
<td>
<form method="POST" action="{{route('mod_zam')}}">
#csrf
<select name="status">
<option value="przyjete"> przyjete</option>
<option value="realizowane"> realizowane</option>
<option value="wyslane"> wyslane</option>
</select>
<input type="hidden" name="id" value="{{$z->id}}" />
<input type="submit" name="modyf" />
</form>
</td>
</tr>
#endforeach
</table>
<ex id=???></ex>
I'm considering doing this in my blade:
const app = new Vue({
el: '#app',
data: {
},
});
But it's not working in blade. My second question - is it possible to create vue instance directly in blade, not via component?
To pass down data to your components you can use props.
You can do something like:
<component is="component" :zID="{{ $z->id }}"></component>
And then in your Example.vue file you have to define your prop. Then you can access it by this.zID.
<script>
export default {
props: ['zId'],
mounted () {
// Do something useful with the data in the template
console.dir(this.zId);
}
}
</script>
You can make inline templates directly in your blade views.
<component :props="{{ $props }}" inline-template>....</component>

Passing the Div id to another vue component in laravel

I created a simple real-time chat application using vue js in laravel.
I am having a problem with the automatic scroll of the div when there is a new data.
What I want is the div to automatically scroll down to the bottom of the div when there is a new data.
Here is my code so far.
Chat.vue file
<template>
<div class="panel-block">
<div class="chat" v-if="chats.length != 0" style="height: 400px;" id="myDiv">
<div v-for="chat in chats" style="overflow: auto;" >
<div class="chat-right" v-if="chat.user_id == userid">
{{ chat.chat }}
</div>
<div class="chat-left" v-else>
{{ chat.chat}}
</div>
</div>
</div>
<div v-else class="no-message">
<br><br><br><br><br>
There are no messages
</div>
<chat-composer v-bind:userid="userid" v-bind:chats="chats" v-bind:adminid="adminid"></chat-composer>
</div>
</template>
<script>
export default {
props: ['chats','userid','adminid'],
}
</script>
ChatComposer.vue file
<template>
<div class="panel-block field">
<div class="input-group">
<input type="text" class="form-control" v-on:keyup.enter="sendChat" v-model="chat">
<span class="input-group-btn">
<button class="btn btn-primary" type="button" v-on:click="sendChat">Send Chat</button>
</span>
</div>
</div>
</template>
<script>
export default{
props: ['chats','userid','adminid'],
data() {
return{
chat: ''
}
},
methods: {
sendChat: function(e) {
if(this.chat != ''){
var data = {
chat: this.chat,
admin_id: this.adminid,
user_id: this.userid
}
this.chat = '';
axios.post('/chat/sendChat', data).then((response) => {
this.chats.push(data)
})
this.scrollToEnd();
}
},
scrollToEnd: function() {
var container = this.$el.querySelector("#myDiv");
container.scrollTop = container.scrollHeight;
}
}
}
</script>
I am passing a div id from the Chat.vue file to the ChatComposer.vue file.
As you can see in the ChatComposer.vue file there is a function called scrollToEnd where in it gets the height of the div id from Chat.vue file.
When the sendchat function is triggered i called the scrollToEnd function.
I guess hes not getting the value from the div id because I am getting an error - Cannot read property 'scrollHeight' of null.
Any help would be appreciated.
Thanks in advance.
the scope of this.$el.querySelector will be limited to only ChatComposer.vue hence child component can not able to access div of parent component #myDiv .
You can trigger event as below in ChatComposer
this.$emit('scroll');
In parent component write ScollToEnd method and use $ref to assign new height
<chat-composer v-bind:userid="userid" v-bind:chats="chats" v-bind:adminid="adminid" #scroll="ScollToEnd"></chat-composer>

How to pass data from one component to other in vue js?

I am learning vue+laravel. I want to pass value from one component to other component? I have used vue router for routing.
Here is the code for first and second component.
SelectPerson.vue
<template>
......
<div>
<input type="number" class="form-control" name="numberOfPersons" placeholder="Enter number of persons here" **v-model="inputPersons"**>
<br>
**<SelectTimeSlot v-bind:numberOfPersons="inputPersons"></SelectTimeSlot>**
</div>
<div>
<button class="btn btn-default float-right mt-2" v-on:click="selectTimeSlots">Next</button>
</div>
......
</template>
<script>
import SelectTimeSlot from './SelectTimeSlot.vue'
export default{
props:['numberOfPersons'],
data(){
return{
**inputPersons:0**
}
},
methods:{
selectTimeSlots(){
this.$router.push({name:'SelectTimeSlot'});
}
}
}
</script>
second component
SelectTimeSlot.vue
<template>
<h5>Welcome, You have selected **{{numberOfPersons}}** persons.</h5>
</template>
Can anybody help me do it?
To pass data from one component to other component, you need to use props:
First component:
<second-component-name :selectedOption="selectedOption"></second-component-name>
<script>
export default {
components: {
'second-component-name': require('./secondComponent.vue'),
},
data() {
return {
selectedOption: ''
}
}
}
</script>
Second Component:
<template>
<div>
{{ selectedOption }}
</div>
</template>
<script>
export default {
props: ['selectedOption']
}
</script>

Hope this is helpful for you!
Say I have a page with this HTML.
<div class="select-all">
<input type="checkbox" name="all_select" id="all_select">
<label #click="checkchecker" for="all_select"></label>
</div>
the function checkchecker is called in my methods
checkchecker() {
this.checker = !this.checker
}
This will show or hide my div on that page like this
<div v-show="checker === true" class="select-all-holder">
<button>Select All</button>
</div>
Now if I also want to toggle another div which is inside my child
component on that page I will pass the value like this.
<div class="content-section clearfix">
<single-product :checkers="checker"></single-product> //This is calling my child component
</div>
Now in my Child component I will have a prop declared like this
checkers: {
type: String,
default: false,
},
This is how I will write my div in my child component
<div v-show="checkers === true" class="select-holder clearfix">
<input type="checkbox" class="unchecked" name="single_select" id="1">
</div>

document.getElementById("id").value = ""; Not working

The code for example document.getElementById("id").value="value"; is not working. I have assigned it on a function to replace the current value of the textbox once the page is loaded.
here is my code
<script type="text/javascript">
function rplace(){
document.getElementById('idtext').value="New Value";
}
onload=rplace
</script>
<form>
<input type="text" id="idtext" name="idtext" value="">
</form>
use jquery insteat of javascript.
$(document).ready(function(){ $("#idtext").val("New Value")});
