Question

i have a dynamic search in php with jquery.
When i’m entering a letter, an ajax call starts.
My problem is, that all ajax calls are working till end, so that every letter is a full call.
When a user is entering a full word then i have unused requests.
How can i stop the unused calls?

Thank you very much

Use timeouts to delay the request for a few millisecond, and clear it when a new key is pressed.

something like

var searchtimeout;
$('#search').keyup( function(){
  if (searchtimeout)
      {
        clearTimeout(searchtimeout);
      }
  searchtimeout = setTimeout(function(){
                                // initiate the ajax call here..
                             }, 300);
} );
