<div id=result></div>
<pre class=js name="code">

// 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;
}
</script>
</pre>
</body>
</html>
