请问beforeSubmit怎么提交包含图片文件的表单?

formData可以上传文件。

formData 提交,自行更换表单id ,url等数据

function doUpload {  
     var formData = new FormData$ "#uploadForm" [0];  
     $.ajax{  
          url: http://localhost/file/upload ,  
          type: POST,  
          data: formData,  
          async: false,  
          cache: false,  
          contentType: false,  
          processData: false,  
          success: function returndata {  
              alertreturndata;  
          },  
          error: function returndata {  
              alertreturndata;  
          }  
     };  
}  

html代码

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <script src="http://libs.baidu.com/jquery/2.1.1/jquery.min.js"></script>
    <title>Title</title>
</head>
<body>
<form id="uploadForm">
    <input name="asas">
    <input name="adsfadsf">
    <input type="file" name="asdfadsasaaa">
    <input name="asasdfasdfasas">
    <input type="button" onclick="doUpload">
</form>
</body>
</html>
<script>
    function doUpload {
        var formData = new FormData$ "#uploadForm" [0];
        $.ajax{
            url: ./form.php ,
            type: POST,
            data: formData,
            async: false,
            cache: false,
            contentType: false,
            processData: false,
            success: function returndata {
                alertreturndata;
            },
            error: function returndata {
                alertreturndata;
            }
        };
    }
