You cannot upload files using AJAX. You could use the jquery.formplugin which uses a hidden iframe:
您不能使用 AJAX 上传文件。您可以使用使用隐藏 iframe的jquery.form插件：
<html>
<head>
<script src="http://code.jquery.com/jquery-latest.js"></script>
<script src="http://malsup.github.com/jquery.form.js"></script>
<script type="text/javascript">
$(document).ready(function(event) {
$('#form1').ajaxForm(function(data) {
$('#result').html(data);
});
});
</script>
</head>
<body>
<form id="form1" action="post.php" method="post" enctype="multipart/form-data">
<h3>Please input the XML:</h3>
<input id="file" type="file" name="file" /><br/>
<input id="submit" type="submit" value="Upload File"/>
</form>
<div id="result">call back result will appear here</div>
</body>
</html>
Also notice the enctype="multipart/form-data"on the form.
还要注意enctype="multipart/form-data"表格上的。
Another possibility is to use the HTML5 File APIwhich allows you to achieve that assuming the client browser supports it.
另一种可能性是使用HTML5 文件 API，假设客户端浏览器支持它，它允许您实现这一目标。

It's not possible to upload files with jQuery $.post, neverthless, with the file API and XMLHttpRequest, it's perfectly possible to upload a file in AJAX, and you can even know how much data have been uploaded yet…
用jQuery $.post 上传文件是不可能的，但是，有了文件API 和XMLHttpRequest，完全可以用AJAX 上传文件，你甚至可以知道已经上传了多少数据……
$('input').change(function()
{
var fileInput = document.querySelector('#file');
var xhr = new XMLHttpRequest();
xhr.open('POST', '/upload/');
xhr.upload.onprogress = function(e)
{
/*
* values that indicate the progression
* e.loaded
* e.total
*/
};
xhr.onload = function()
{
alert('upload complete');
};
// upload success
if (xhr.readyState == 4 && (xhr.status == 200 || xhr.status == 0))
{
// if your server sends a message on upload sucess,
// get it with xhr.responseText
alert(xhr.responseText);
}
var form = new FormData();
form.append('title', this.files[0].name);
form.append('pict', fileInput.files[0]);
xhr.send(form);
}

No no no, you should use a jQuery form plugin for async uploading files. You can't upload file with jQuery $.post method. The file will be uploaded with hidden iframe
不不不，您应该使用 jQuery 表单插件来异步上传文件。你不能用 jQuery $.post 方法上传文件。该文件将使用隐藏的 iframe 上传
Another way is to use HTML5 uploading with FileAPI/BlobApi
另一种方法是使用带有 FileAPI/BlobApi 的 HTML5 上传

Try uploading with an iframe because you can't send a file with $.post method.
尝试使用 iframe 上传，因为您无法使用 $.post 方法发送文件。
