In this tutorial we’re going to learn how to using Onchange function in laravel using javscript.

Put below code

onsole.log('email me ky aa gaya edit ke page pe' + html.data.admin_email);
if ($('#project_manager option[value="' + adminEmail + '"]').length ===
    0) {
    $('#project_manager').append('<option value="' + adminEmail + '">' +
        adminEmail + '</option>');
}
$('#project_manager').val(adminEmail);

Next put below code

$(document).on('click', '.edit', function() {
                console.log('working edit button');
                $('#name_form').show();
                var id = $(this).attr('id');
                $('#form_result').html('');
                $.ajax({
                    type: "get",
                    data: {},
                    url: "{{ url('/api/v1/j/project/edit/') }}/" + id,
                    headers: {
                        "Authorization": "Bearer " + localStorage.getItem('a_u_a_b_t')
                    },
                    success: function(html) {
                        var adminEmail = html.data.admin_email;
                        if ($('#project_manager option[value="' + adminEmail + '"]').length ===
                            0) {
                            $('#project_manager').append('<option value="' + adminEmail + '">' +
                                adminEmail + '</option>');
                        }
                        $('#project_manager').val(adminEmail);
                        console.log('value aa gaya edit ke page pe');
                        console.log('email me ky aa gaya edit ke page pe' + html.data
                            .admin_email);
                        console.log(html);
                        $('#project_name').val(html.data.project_name);
                        $('#project_manager').val(html.data.admin_email);
                        $('#url').val(html.data.url);
                        $('#sa_id').val(html.data.sa_id);
                        $('#sa_email').val(html.data.admin_email);
                        $('.modal-title').text("Edit Project");
                        $('.modal-title_delete').text("Project Delete");
                        $('#action_button').val("Update");
                        $('#action').val("Update");
                        $('#formModal').modal('show');
                        $('#hidden_id').val(id);
                    }
                })
            });

Go to blade page and put below code

<div class="form-group" id="name_form">
    <label class="control-label">Project Manager</label>
    <select name="project_manager" id="project_manager" class="w-100 p-2">
        <option value="" class="form-controll text-dark">Select Manager </option>
        <option value="{{ Auth::user()->email }}">{{ Auth::user()->email }}</option>
    </select>
</div>
