The automatic opening of a modal in a Livewire component is not functioning as expected

I am having trouble displaying a modal when my component initializes. I have tried using $this->emit('show) to open the modal

When I add a button in my view, the emit('show') works! However, I want the modal to be automatically shown when the view is loaded

This is the code for my component:

public function mount($id)
{
    if ($id != null) {
        try {
            $data = DetalleRamComputadora::find($id);
            $this->fk_ram_tecnologia    = $data->fk_tecnologia;
            $this->fk_ram_capacidad     = $data->fk_capacidad;
            $this->fk_ram_frecuencia    = $data->frecuencia;

            $this->emit('show'); // Open the modal
        } catch (\Throwable $th) {
            // Handle error
        }
    }
}

This is the script in my view:

<script type="text/javascript">

    window.livewire.on('show', () => {
         $('#exampleModal').modal('show');
    });
    
</script>

And here is the markup for my modal:

<div wire:ignore.self class="modal fade" id="exampleModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
<div class="modal-dialog modal-lg" role="document">
    <div class="modal-content">
        <div class="modal-header">
            <button type="button" class="close" data-dismiss="modal" aria-label="Close" >
                 <span aria-hidden="true close-btn">×</span>
            </button>
        </div>
        <div class="modal-body">
            ...
        </div>
        <div class="modal-footer">
            ...
        </div>
    </div>
</div>

Answer №1

The emit is happening before the DOM finishes loading, causing your script not to execute properly.

Here's a suggestion:

wire:init="openModal"

inside

<div wire:init="openModal" wire:ignore.self class="modal fade" id="exampleModal"...

And in your component file:

 public function openModal()
 {
     $this->emit('show');
 }

Another option:

You can also try this approach:

<script>
    $(document).ready(function () {
        window.livewire.emit('show');
    });

    window.livewire.on('show', () => {
        $('#exampleModal').modal('show');
    });
</script>

Much simpler!
