Uncaught TypeError: Cannot read property 'options' of undefined

[Darin Gilchrist]

Let me start off by saying that I love the blueimp jQuery File Upload utility, and am excited about the jQuery UI branch!

I am getting the following error message when trying to upload through Chrome, and similar errors in other browsers:

Uncaught TypeError: Cannot read property 'options' of undefined

Seems to be line 87 of the "jquery.fileupload-ui.js" file, which reads:

var that = $(this).data('fileupload'),

options = that.options,

files = data.files;

This happens in the latest download package, after selecting a file and attempting to initiate the upload.

The demo code in the download package has the same issue, so I believe it's not just me seeing this. How can I fix this? Known issue?

Thanks for your help!

Yes I have exactly the same problem.  The basic & basic-plus ones work but not the ui or angular.

Also the links to the JS files are incorrect.  load-image.min.js, canvas-to-blob.min.js & bootstrap.min.js  Corrected by download from the online working demo.

I have update the links on my site, but for some reason it will not show the list of files?

any ideas?

This problem cost me a lot of time and energy. It seems to be a jQuery version problem. The plugin I downloaded referenced 1.7.1. and I was using 1.10.2. I found that changing $(this).data('fileupload') to $(this).data('blueimpUI-fileupload') worked for me.

I found that out by reading a comment from " aburakab" here (and pasted below): https://github.com/blueimp/jQuery-File-Upload/issues/2084. I hope this helps!

I tried $(this).data('blueimpUI-fileupload') ... scripts taken from MVC 3 Sample

and it works with me.

Yes I faced same problem and it  is due to version changed ... 1.7.1 to 1.11.0
This is resolved by replacing  $(this).data('fileupload') to $(this).data('blueimpUI-fileupload') everywhere at jquery.fileupload-ui.js file..
Thanks
