Ajava界面:
<!DOCTYPE html> <html> <head> <script> function loadXMLDoc() { var xmlhttp; if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); } else {// code for IE6, IE5 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.onreadystatechange=function() { if (xmlhttp.readyState==4 && xmlhttp.status==200) { document.getElementById("myDiv").innerHTML=xmlhttp.responseText; } } xmlhttp.open("GET","send.php?name=sunzhiyan",true); xmlhttp.send(); } </script> </head> <body> <div id="myDiv"><h2>Let AJAX change this text</h2></div> <button type="button" onclick="loadXMLDoc()">Change Content</button> </body> </html>
PHP界面:
<?php if($_GET[‘name‘] == sunzhiyan){ echo ‘this is right‘; }else{ echo ‘this is error‘; } ?>
这事最简单的一个Ajax的运用,能够实现,Ajax的验证
