如何停止在检测表单是否已提交的 function 之外启动的 setTimeout？

Question

My setTimeout starts when the page is loaded, I need to stop it as soon as the user clicks the button and submit the form, the variable seems to get lost and I can't stop, any tips?

my code

$(function() {

        function atualiza(){
            $.get('online.php?p=SMS', 
            function(resultado){
                $('#onlineagora').html(resultado);
            });
        }

        timer1 = setTimeout('atualiza()', 850);
            
        $('#formsms').submit(function( event ) {
            $.ajax({
                url: 'aguardesms.php',
                type: 'POST',
                dataType: 'html',
                data: $('#formsms').serialize(),
                success: function(content){
                    clearTimeout(timer1);//STOP ATUALIZA
                    $("#DisplayDiv").html(content);
                }  
            });
            event.preventDefault();
        });
    });

solved using setInterval/clearInterval

var timer1 = setInterval(atualiza, 850);
function atualiza(){
    $.get('online.php?p=SMS', 
    function(resultado){

    });
}
$('#formsms').submit(function(e){
e.preventDefault();
clearInterval(timer1);
$.ajax({
        url: 'aguardesms.php',
        type: 'POST',
        dataType: 'html',
        data: $('#formsms').serialize(),
        success: function(content){
            $("#DisplayDiv").html(content);
        }  
    });
});
