jquery.uploadify Dynamic Transfer Parameters

The ability to upload files is implemented in recent projects using Uplaodify. In the transmission of dynamic parameters, encountered a problem!

Using the settings method provided on the website

Official examples
function Changebtntext () {
$ (' #file_upload '). Uploadify (' Settings ', ' ButtonText ', ' BROWSE ');
}

The first parameter must be ' settings '

The second parameter cannot be set casually. (I was in this place, took some time)

The third parameter is a value.

I arbitrarily set a string in the second argument, but request["parameter name" gets the value. Later, looked at the jquery.uploadify.js, only to find that

The value of the second parameter is specific to a few. If the parameter is passed, the formData is used;

The third parameter passes a JSON-formatted data. If {"name": "MyName"}

The server (written in C #) Gets the value when request["name" is available.

Fileobjname This property, using request["attribute value" is not worth it. Use request.files[the value of the Fileobjname property to fetch the value.

Note: When I write this, it seems to be a bit clear, why the second parameter is a specific value, the settings method is to set the property, the second parameter is the name of the property in Uploadify.
