□ 其它传递用户信息方式

1、在JQuery File Upload初始化js文件中,通过post方式

   1:      $('#fileupload').bind('fileuploadsubmit', function (e, data) {
   2:          // The example input, doesn't have to be part of the upload form:
   3:          var $context = $('#objContext');
   4:          data.formData = { example: $context.val() };
   5:      });

.csharpcode, .csharpcode pre
{
font-size: small;
color: black;
font-family: consolas, "Courier New", courier, monospace;
background-color: #ffffff;
/*white-space: pre;*/
}
.csharpcode pre { margin: 0em; }
.csharpcode .rem { color: #008000; }
.csharpcode .kwrd { color: #0000ff; }
.csharpcode .str { color: #006080; }
.csharpcode .op { color: #0000c0; }
.csharpcode .preproc { color: #cc6633; }
.csharpcode .asp { background-color: #ffff00; }
.csharpcode .html { color: #800000; }
.csharpcode .attr { color: #ff0000; }
.csharpcode .alt
{
background-color: #f4f4f4;
width: 100%;
margin: 0em;
}
.csharpcode .lnum { color: #606060; }

2、在JQuery File Upload初始化js文件中,通过get方式

var fileUploadUrl = "/Backload/UploadHandler" + "&objectContext=user123";
