AJAX 客户端页面代码： index.html

<html> <body> <h1>Ajax file upload sample</h1><br/><input type="button" value="上传测试"/> <div id=result></div> <PRE class=js><SCRIPT LANGUAGE=JavaScript> // 上传函数 function btn_send.onclick() { data = "" spliter = "-------7d8d733180846" datadata = data + spliter + "\r\n" datadata = data + "Content-Disposition: form-data; name=\"photofile\"; filename=\"C:\\a.txt\"\r\n" // datadata = data + "Content-Type: image/pjpeg" + vbCrLf datadata = data + "Content-Type: text/plain" + "\r\n" + "\r\n" text = "My name is Wilson Lin." postLength = text.length + data.length + 2 + spliter.length + 4 package = data + text + "\r\n" + spliter + "--\r\n" alert(package) // 把XML文档发送到Web服务器 var xmlhttp = new ActiveXObject("Microsoft.XMLHTTP"); xmlhttp.open("POST","./upload.php",false); xmlhttp.setRequestHeader("Content-Type", "multipart/form-data; boundary=-----7d8d733180846"); xmlhttp.setRequestHeader("Content-Length", postLength); xmlhttp.send(package); // 显示服务器返回的信息 result.innerHTML=xmlhttp.ResponseText; } </SCRIPT> </PRE> </body> </html>

PHP服务器端代码： upload.php

<?php // $_FILES['photofile']:是获得上传图片的数组 // $uploadfile：存放地址 $uploadfile = "D:/".$_FILES['photofile']['name']; copy( $_FILES['photofile']['tmp_name'], $uploadfile ); echo "URL: <a href='http://localhost/".$_FILES['photofile']['name']."' target='_blank'>".$_FILES['photofile']['name']."</a><br/>"; ?> Upload successed!
