Uncaught TypeError

I am trying to run my application and I am continually getting below mentioned error "Uncaught TypeError: Cannot set properties of undefined (setting 'unobtrusive')". Because of this error my application is breaking and content of it is not loading. Someone please guide how can I resolve this error.

I guess the error says the application is trying to load "unobtrosive.js" before"jquery.js" in its relevant razor file (like root.head or third party razor file).
you can also check where this error occurs in the browser console and also where and how "unobtrosive.js" is being loaded in the source code , then post it here to help finding the issue.
