jquery的post方法上传文件问题。

用jQuery 的Ajax文件上传的组件：ajaxfileupload.js

<script type="text/javascript" src="jquery.js"></script>

<script type="text/javascript" src="ajaxfileupload.js"></script>

<script type="text/javascript">

function ajaxFileUpload()

{

$.ajaxFileUpload

(

{

url:'doajaxfileupload.php', //你处理上传文件的服务端

secureuri:false,

fileElementId:'img',

dataType: 'json',

success: function (data)

{

alert(data.file_infor);

}

}

)

return false;

}

</script>

<input id="img" type="file" size="45" name="img" class="input">

<button class="button" id="buttonUpload" onclick="return ajaxFileUpload();">Upload</button>
