<td>
<button class="btn btn-info"
data-toggle="modal" data-target="#edit">Edit</button>
<button class="btn btn-danger"
data-toggle="modal" data-target="#dlt">Delete</button>
</td>
<--------------------->
<div class="modal fade" id="edit" tabindex="-1" role="dialog" aria-
labelledby="myModalLabel">
<div class="modal-dialog" role="document">
<div class="modal-content">
<form method="post" action="">
#method('PATCH')
#csrf
<div class="modal-header">

aria-label="Close"><span aria-hidden="true">×</span></button>
<h4 class="modal-title" id="myModalLabel">Modal title</h4>

<div class="modal-body">

There no difference between using ajax in PHP and laravel.
html adjustment, add this meta inside your html head.
<meta name="csrf-token" content="{{ csrf_token() }}" />
Update your delete button and add a hidden field inside your delete modal body.
<button class="btn btn-danger btn-delete-project" data-toggle="modal" data-target="#dlt" data-project-id="{{ $pro->id}}">Delete</button>
<input type="hidden" name="project_id" id="project_id" value="">
<button type="submit" class="btn btn-info delete-project-confirm">Yes, Delete</button>
Get Your deleted row,
<tr data-row-id="{{ $pro->id }}">
</tr>
Define your ajax function, there are many defferent technique you can do it. A simple one below.
/**
* project delete confirm modal
*/
$(document).on('click', '.btn-delete-project', function (e) {
e.preventDefault();
var projectId = $(this).data('project-id');
$('#dlt #project_id').val(projectId);
});
$.ajaxSetup({
headers: {
'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
}
});
/**
* ajax call
*/
// give your delete button id
$(document).on('click', '.delete-project-confirm', function (e) {
e.preventDefault();
var projectId = $('#dlt #project_id').val();
var deletedRow = $('tr[data-row-id="' + projectId + '"]');
$.ajax({
type: 'delete',
url: '/project/' + projectId,
success: function () {
$('#dlt').modal('toggle');
deletedRow.remove();
// toastr.success('Order Has Been Deleted Successfully.');
},
error: function(XMLHttpRequest) {
// toastr.error('Something Went Wrong !');
}
});
});
In your ProjectController destroy() method,
public function destroy($id)
{
// dd($id);
$project = Project::findOrFail($id);
// dd($project);
$project->delete();
}
