前台:

<html xmlns="http://www.w3.org/1999/xhtml">

</head>
<script type="text/javascript" src="js/jquery.js"></script>
<script type="text/javascript" src="js/ajaxfileupload.js"></script>
<script type="text/javascript">
function ajaxFileUpload(){
loading();//动态加载小图标
$.ajaxFileUpload ({
 url:'upload.php',
 secureuri:false,
 fileElementId:'img',
 dataType: 'json',
 success: function (data){
 $("input").before("<p>"+data+"</p>");
 }
 
 }) 
 return false;
}
function loading(){
  $("#loading").ajaxStart(function(){
 $(this).show();
  }).ajaxComplete(
   function(){
   $(this).hide();
 });
}
</script>
<body> 
<input id="img" type="file" size="45" name="img" class="input">
<input type="text" placeholder="看看上传文件的时候有没有刷新这个页面"
<button class="button" id="buttonUpload" onclick="return ajaxFileUpload();">Upload</button>
<img id="loading" src="img/loading.gif" style="display:none;">
</body>
</html>

php端upload.php配合前台完成上传:

<?php
  $upFilePath = "img/upload/";
  if(file_exists($_FILES['img']['tmp_name']))
  $ok=@move_uploaded_file($_FILES['img']['tmp_name'],$upFilePath.$_FILES['img']['name']);
  if($ok === FALSE){
    echo json_encode('上传失败');
  }else{
    //echo json_encode($_FILES['img']['tmp_name']);
	echo json_encode('文件异步上传成功!');
  }
?>
