可以考虑用form+iframe模拟AJAX异步上传:

form的target设为页面内的一个iframe,让这个iframe显示action请求后的内容.

能够实现单页面多处多图片预览上传,不需要任何插件,支持IE8.

if(isset($_POST['submit']) && !empty($_FILES['file'])) {

$i = 0;

foreach( $_FILES['file']['name'] as $v ) {

move_uploaded_file($_FILES['file']['tmp_name'][$i], 'uploads/'.$v);

$i++;

}

header('Content-Type: text/html; charset=utf-8');

echo '';

foreach( $_FILES['file']['name'] as $v ) {

echo '

---

';

}

exit();

}

if(isset($_POST['submit2']) && !empty($_FILES['file2'])) {

$i = 0;

foreach( $_FILES['file2']['name'] as $v ) {

move_uploaded_file($_FILES['file2']['tmp_name'][$i], 'uploads/'.$v);

$i++;

}

header('Content-Type: text/html; charset=utf-8');

echo '';

foreach( $_FILES['file2']['name'] as $v ) {

echo '

---

';

}

exit();

}

?>

jQuery "AJAX" upload

* { margin: 0; padding: 0; }

#con { width: 360px; margin: 10px; }

input { display: block; margin: 10px; }

$(document).ready(function(){

$('input.submit').click(function(){

$('iframe.ul_frame').show();

});

$('input.submit2').click(function(){

$('iframe.ul_frame2').show();

});

});
