Missing features in jQuery [closed]

Question

jQuery is a very popular JavaScript framework nowadays. You can tell that based on number of jQuery tags on this site for example.

I haven't used any other JS frameworks and I would like to get your opinion on some of features you can think of that the library is missing.

• What would you change in the project?
• What would you add?
• Are there any features that you think are worthless?
• What features famous in other JS frameworks you would like to see in jQuery?

Answer 1

The JavaScript libraries I used the most are jQuery, YUI and ExtJS (Core).

My favorite though remains jQuery, but I still would like some of ExtJS Core's functionality in it.

First time I worked with ExtJS I fell in love with it's inheritance system, I personally think it's very ingenious and I would love to have it in jQuery. Still I recently found one of John Resig's projects (the creator of jQuery) 'Simple JavaScript Inheritance' (you can find it here) and it seems to be very powerful and small.

Another feature I would like to see in jQuery would be a much more intelligent extension system.

Other things I wouldn't change in jQuery, I think it's the most perfect choice for a JavaScript library, for a very broad range of applications.

For widgets I prefer ExtJS than jQuery UI

Answer 2

Not sure whether anybody else would want it, but I wouldn't mind a .revert() function that "undoes" any changes you've made to an item or selector since the page was loaded.

eg. You might change the colour, size, and a couple of attributes of a div while you go through. Calling .revert() on the selector would undo these changes.
