how to automatically reload a page after jquery ajax is finished

here is my code for uploading some images on server
everything works except success – reloading the page after uploading is finished
I tried with another params – for example 20000 – without success
please help

inpfi.on('change', function(){
    var flist = inpfi[0].files;
    var fd = new FormData();
    for(let i = 0; i < flist.length; i++){fd.append('flist[]', flist[i]);}
    $.ajax({
        url: 'a_slike_up.php', 
        type: 'post',
        data: fd,
        dataType: 'json',
        contentType: false,
        processData: false,
        success: function(){setInterval('location.reload()', 7000);}
    })
});
