<script>
/*原生JS版*/
document.getElementById("upJS").onclick = function() {
 /* FormData 是表单数据类 */
 var fd = new FormData();
 var ajax = new XMLHttpRequest();
 fd.append("upload", 1);
 /* 把文件添加到表单里 */
 fd.append("upfile", document.getElementById("upfile").files[0]);
 ajax.open("post", "test.php", true);

 ajax.onload = function () {
 console.log(ajax.responseText);
 };

 ajax.send(fd);
 
}

/* jQuery 版 */
