问题
I'm using the jQuery plugin "jQuery-File-Upload" to manage a form I have. I've tried searching for my problem on google but nothing so far.
The problem is that this form allows an optional field for file upload. When I insert a file it all goes ok, but when I decide to not include a file the plugin script won't even run.
Now I know this is a plugin specifically to upload files, nevertheless it becomes rather inconvenient if we have to duplicate code just to provide an alternative AJAX call for submissions without files.
Is there a way to solve this issue?
Thanks Peter
update to add code:
form.fileupload
(
{
url : 'php/file.php',
dataType : 'json',
autoUpload : false,
replaceFileInput : false,
sequentialUploads : false,
maxFileSize : 10000000,
minFileSize : 0,
acceptFileTypes : /(\.|\/)(gif|jpe?g|png)$/i,
add : function (e, data)
{
data.context = button.click
(
function (e)
{
e.preventDefault ();
// PARSE DATA FOR VALIDATION
// OK TO SEND
data.submit();
}
);
},
fail : function (e, data)
{
console.log ('fail');
console.log (data);
},
progressall : function (e, data)
{
console.log ('progress');
console.log (progress);
},
done : function (e, data)
{
console.log ('done');
console.log (data);
}
}
);

I had the response from the author saying this option is not implemented on the framework: https://github.com/blueimp/jQuery-File-Upload/issues/3105.
I decided to go with a different jQuery plugin http://malsup.com/jquery/form/ that doesn't force me to duplicate code for a form submission with or without file attached methods. Works in IE9.
