adding methods to Object prototype causes an error when twitter bootstrap modal is closed
jquery, twitter-bootstrap
Solution
This has to do with jQuery and extending Object.prototype.
See this question: Prototyping Object in Javascript breaks jQuery?
Essentially, you should avoid extending Object.prototype, but see the answer for more details.
Problem
I have a very weird issue. I'm using Twitter Bootstrap 2. I have a modal dialogue on a page, which I am opening like this: ` $('#rights-dialogue).modal(); ` I am also adding a custom function to the `Object.prototype` object, like this: ` Object.prototype.foo = function (a) {}; ` When the `x` button in the modal dialogue is clicked, the dialogue closes, but the black background remains and I get a strange jQuery error in the jQuery event handling code: ` Uncaught TypeError: Cannot read property 'origType' of undefined ` If I remove all arguments from my `foo()` function, I do not not get this error, and everything works fine. Here is a jsfiddle that illustrates the issue: http://jsfiddle.net/nicholascloud/r6T8z/5/. I have no idea what's going on here. EDIT: A few other things I've noticed. It doesn't seem to matter what the name of the method is on Object.prototype. Any method with arguments will cause this error. If a method is added with no arguments, the error does not occur. The error occurs when jQuery detaches the event listener `keyup.dismiss.modal` from the DOM. I have confirmed this error with jQuery 1.7.1 and 1.7.2, but my suspicion is that its a Twitter Bootstrap problem and not jQuery per se.
