修改了下dropzonejs的demo上傳頁面：（原位址：http://www.dropzonejs.com/exa...）加了個textarea，想實作檔案上傳處理完成後將處理結果回顯到textarea內，請問該如何處理？
以下是index.php檔案內容：
<code><!DOCTYPE html>
<meta charset="utf-8">
<title>Dropzone simple example</title>
<!--
DO NOT SIMPLY COPY THOSE LINES. Download the JS and CSS files from the
latest release (https://github.com/enyo/dropzone/releases/latest), and
host them yourself!
-->
<script src="https://rawgit.com/enyo/dropzone/master/dist/dropzone.js"></script>
<link rel="stylesheet" href="https://rawgit.com/enyo/dropzone/master/dist/dropzone.css">
<p>
This is the most minimal example of Dropzone. The upload in this example
doesn't work, because there is no actual server to handle the file upload.
</p>
<!-- Change /upload-target to your upload address -->
<form action="upload_file.php" class="dropzone"></form>
<div >
<textarea class="result" rows="16" cols="265" id="res"></textarea>
</div></code>
以下是upload_file.php檔案內容：
<code><?php
echo "---start---\n";
if ($_FILES["file"]["error"] > 0) {
echo "Error: " . $_FILES["file"]["error"] . "<br />";
} else {
echo "Upload: " . $_FILES["file"]["name"] . "<br />";
echo "Type: " . $_FILES["file"]["type"] . "<br />";
echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb<br />";
echo "Stored in: " . $_FILES["file"]["tmp_name"];
$content = file_get_contents($_FILES["file"]["tmp_name"]);
echo $content;
}
?></code>

可以透過ajax取得上傳後的圖片地址，然後顯示
