下面是我的非工作的尝试：

Here's my nonworking attempt:

<script>
    function uploadImageSubmit() {

        var imageFile = $('.imageFile').val();

        $.ajax({

            url: 'ajax.php?request=upload-image&file='+imageFile,
            success: function(output) {
                 alert(output);                    
            }

        });

    }
</script>

<h2>Upload File</h2>

<form>
    <input type="file" class="imageFile" />
    <a onClick="uploadImageSubmit()">Upload</a>
</form>

在ajax.php的code：

The code on "ajax.php":

<?php

$action = $_GET['request'];

switch($action) {

    case 'upload-image':

        $imageFile =  $_GET['file'];

        $name = $_FILES[$imageFile] ['name'];
        $tmpLocation = $_FILES[$imageFile] ['tmp_name'];

            $upload = move_uploaded_file($tmpLocation, "files/$name");
            echo ($upload) ? $name.' uploaded successfully!' : 'File not uploaded.';

    end;

}

?>

我得到没有上传信息文件。我想这是因为，即使字符串可以通过URL传递，文件路径不能出于某种原因。但是，有一次我不知道为什么它不工作。有人能找出什么是错的吗？

I get the message file not uploaded. I think it's because even though strings can be passed via the url, File paths can't for some reason. But then again I have no idea why it's not working. Can someone figure out what's wrong please?

推荐答案

其实， HTML5和新的文件API 通过XmlHtt prequest不支持上传。它精美的作品在Firefox 4和Chrome。

Actually, HTML5 and the new File API does support uploading via XmlHttpRequest. It works beautifully in Firefox 4 and Chrome.
