Methods to add additional parameters to jquery's ajaxfileupload

Direct way:

$.ajaxFileUpload({
data:{"a":123,"b":456};//Additional parameters in json format
});

Then, in the ajaxfileupload.js file, I modify two functions, which are essentially a function (add a new argument to the function).

The first place:

createUploadForm: function(id, fileElementId,data){} Is greater than the 26 Ok. 

Then add the following code to the function body:

if (data) {  
    for (var i in data) {  
        $('<input type="hidden" name="' + i + '" value="' + data[i] + '" />').appendTo(form);  
    }  
}

What the code does: work with json data, adding type='hidden' input to the form form

The second section:

ajaxFileUpload(){}
var form = jQuery.createUploadForm(id, s.fileElementId,s.data); Modify this line, just add one more parameter to it. 

This modification is actually about the parameters of the function call.
