AJAX 客户端页面代码： index.html

Ajax file upload sample

// 上传函数
function btn_send.onclick() {
data = ""
spliter = "-------7d8d733180846"
datadata = data + spliter + "rn"
datadata = data + "Content-Disposition: form-data; name="photofile"; filename="C:a.txt"rn"
// datadata = data + "Content-Type: image/pjpeg" + vbCrLf
datadata = data + "Content-Type: text/plain" + "rn" + "rn"
text = "My name is Wilson Lin."
postLength = text.length + data.length + 2 + spliter.length + 4
package = data + text + "rn" + spliter + "--rn"
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;
}

PHP服务器端代码： upload.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: ".$_FILES['photofile']['name']."
";

?>

Upload successed!
