buonasera a tutti...
mi trovo con questo codice diprova
codice:<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <script type="text/javascript" language="javascript"> function get(page,destination) { makeRequest(page, destination); } var http_request = false; function makeRequest(url, destination) { http_request = false; if (window.XMLHttpRequest) { // Mozilla, Safari,... http_request = new XMLHttpRequest(); if (http_request.overrideMimeType) { // set type accordingly to anticipated content type //http_request.overrideMimeType('text/xml'); http_request.overrideMimeType('text/html'); } } else if (window.ActiveXObject) { // IE try { http_request = new ActiveXObject("Msxml2.XMLHTTP"); } catch (e) { try { http_request = new ActiveXObject("Microsoft.XMLHTTP"); } catch (e) {} } } if (!http_request) { alert('Cannot create XMLHTTP instance'); return false; } http_request.onreadystatechange = alertContents(destination); http_request.open('GET', url, true); http_request.send(null); } function alertContents(destination) { if (http_request.readyState == 4) { if (http_request.status == 200) { //alert(http_request.responseText); result = http_request.responseText; destr="document.getElementById('"+destination+"').innerHTML = result;"; eval(destr); //document.getElementById(''+destination+'').innerHTML = result; } else { alert('There was a problem with the request.'); } } } </script> </head> <body> <input type="button" name="test" value="test" onclick="get('test.php?page=http://www.google.it','pagina');"> <div id="pagina"> </div> </body> </html>
in questo passaggio
codice:http_request.onreadystatechange = alertContents(destination);
destinatione viene passata ma non viene aggiornato il contenuto del div!codice:result = http_request.responseText; destr="document.getElementById('"+destination+"').innerHTML = result;"; eval(destr);
cosa sbaglio??
