Uncaught TypeError: X[g].exec is not a function fb tokenize

Question

Since today I am getting an error as follows:

Uncaught TypeError: X[g].exec is not a function fb tokenize

This is the stack trace:

Uncaught TypeError: X[g].exec is not a function fb.tokenize @ jquery.min.js:2 fb.compile @ jquery.min.js:2 fb.select @ jquery.min.js:2 fb @ jquery.min.js:2 m.event.handlers @ jquery.min.js:3 m.event.dispatch @ jquery.min.js:3 r.handle @ jquery.min.js:3

The project is an Angularjs app built in an .NET MVC Area. Dependencies are:

http://cdnjs.cloudflare.com/ajax/libs/toastr.js/latest/css/toastr.min.css and corresponding js
https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js
/Resources/Libs/AngularJS/Libs/angular-file-upload-shim.min.js
/Resources/Libs/AngularJS/Libs/bootstrap.min.js/Resources/Libs/AngularJS/Libs/wysihtml5-0.3.0.min.js
/Resources/Libs/AngularJS/Libs/bootstrap3-wysihtml5.js
http://cdnjs.cloudflare.com/ajax/libs/toastr.js/latest/js/toastr.js"

Edit

Seems to be a problem with Bootstrap.js file, where an alert is supposed to be dismissed but not found. JQuery Sizzle can't find "[alert-dismiss]". The fb is Sizzle in minified version of JQuery.

I recommend finding out more information about what exactly is broken here. One way do approach this would be to not use minified versions of the code involved in your development/testing setup, and include debug symbols wherever appropriate. — derabbink, May 01 '15 at 10:31

I had the same X[g].exec is not a function error and in my case it was because i defined a Object.prototype.count function.

I had a similar experience and it drives home the point - do not extend the Object prototype. It will mess up jQuery (I'm willing to bet Gecko IT's solution was because bootstrap extends the Object). – Rex the Strange Feb 22 '20 at 15:10

I found the culprit.

Seems there was a disturbance in the force with the combination of bootstrap.js and the angular bootstrap ui library. After removing the unnecessary bootstrap.js all was well.

To solve that, add the following to your code:

Function.prototype.exec = Object.prototype.exec = function() {return null};

In my case, I was trying to get the index of a non-indexed array to iterate it. The code was:

Object.prototype.getByIndex = function(index) {
    return this[Object.keys(this)[index]];
  };

this keyword represented the data I was trying to get the index of. So using it would be:

// ...
const element = groupedData.getByIndex(index);
// ...

To fix this, I modified it to be a regular function, then pass the data as a parameter. The new function would look like this:

function getByIndex(grupData, index) {
    return grupData[Object.keys(grupData)[index]];
  };

And passing the data:

const element = getByIndex(groupedData, index);
