Search bar and checkbox JQuery

I made a search bar to search an app and a checkbox to filter apps by platforms but when I write something on the search bar and click on a button of my checkbox, the search bar value is not taken into account and I have to rewrite something to update the research by platform. What should I add to take into account my search bar value when I click on a checkbox button? thanks

<script>
                        $(document).ready(function(){
                            $("#searchapp").on("keyup", function() {
                                var value = $(this).val().toLowerCase();
                                var platform = $('#checkbox input:checked').attr('name');
                                    $("#table .anapp:contains('" + platform + "')").filter(function() {
                                        $(this).toggle($(this).text().toLowerCase().indexOf(value) > -1)
                                    });


                            });


                             $("#ios").click(function(){
                                 $(this).prop('checked', true)
                                 $('#android').prop('checked', false)

                                 $(".anapp").hide();
                                 $(".anapp:contains('iOS')").show();

                             });

                             $("#android").click(function(){
                                 $(this).prop('checked', true)
                                 $('#ios').prop('checked', false)


                                 $(".anapp").hide();
                                 $(".anapp:contains('Android')").show();


                             });
                         });

                        </script>
