php - I can't refresh a div in my web -


i'm trying refresh part of web, div, found code this, doesn't works. seems it's correct doesn't works. don't understand happens, tried other jquery codes , doesn't work too.

this html file:

<!doctype html> <html> <head>     <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>     <script>         var timer;         var seconds = 1;           $( document ).ready(function(){            startactivityrefresh()         });          function startactivityrefresh() {             timer = setinterval(function() {                 $('#div1').load('prova.php');             }, seconds*1000)         }     </script> </head> <body>     <div id="div1"></div> </body> </html> 

and php file:

<?php     echo "prova"; ?> 

when go browser , reload page doesn't show anything. should show prova. (the php file test)

[resolved] problem in browser, firefox blocked content. there shield in url bar unblock it.

as mentioned, never called startactivityrefresh()

try this.

<script>     var timer;     var seconds = 1;       $( document ).ready(function(){         startactivityrefresh()     });      function startactivityrefresh() {         timer = setinterval(function() {             $('#div1').load('prova.php');         }, seconds*1000)     } </script> 

until called, function hanging out, waiting other piece of code need it.

i should mention there @ least 2 ways call function on page load. $(document).ready , $(window).onload. here's discussion on difference.

edit:

here's fiddle demonstrates basic idea.
