How to refresh a table on the parent page when I close a popup window in PHP?

Question

I have a table on a parent page users.php, populated with datas from mySQL. I have a button on the row ADD USER that opens a popup window that allows to add an user. The button is hidden when the user is already registered. I would like to refresh only the table and not the entire page when I close the popup after the form has been submitted. How can I do it properly?

Answer 1

using jquery

Create function with javascript in parent window something like

function reloadTable(){
 $.ajax({
 url: "tabledata.php",
 cache: false
 })
  .done(function( html ) {
    $( "#tablename" ).html( html );
  });
}

then in the child window use

    $( window ).unload(function() {
     window.opener.reloadTable();
   });
