文件上传拖拽效果，以及图片，MP3，MP4格式的预览，ajax上传

1.创建upload.html,最后引入zphupload.js(注意放在最后)

<meta charset="utf-8"> <div id="drop_area" >将图片拖拽到此</div> <button onclick="zphxhrupload('upload.php')">ajax上传</button> <script src="zphupload.js"></script>

2.创建upload.php

<?php print_r($_FILES["file"]); $name = $_FILES["file"]["name"]; //中文可能乱码使用iconv函数 move_uploaded_file($_FILES["file"]["tmp_name"],iconv("UTF-8","gb2312",$name)); ?>
