Question

Can anybody tell me how to refresh the current page with JavaScript, having a POST variable modified or added?

To be clear, I want to set some POST variables prior to reloading the page.

Answer 1

By using jquery ajax you can reload your page

$.ajax({
    type: "POST",
    url: "packtypeAdd.php",
    data: infoPO,
    success: function() {   
        location.reload();  
    }
});
