Question

We’re considering switching our site from Prototype to jQuery. Being all-too-familiar with Prototype, I’m well aware of the things about Prototype that I find limiting or annoying.

My question for jQuery users is: After working with jQuery for a while, what do you find frustrating? Are there things about jQuery that make you think about switching (back) to Prototype?

Answer 1

Probably the only real issue I’ve ever ran into is $(this) scope problems. For example, if you’re doing a nested for loop over elements and sub elements using the built in JQuery .each() function, what does $(this) refer to? In that case it refers to the inner-most scope, as it should be, but its not always expected.

The simple solution is to just cache $(this) to a variable before drilling further into a chain:

$('li').each(function() {     // cache this     var list_item = $(this);     // get all child a tags     list_item.find('a').each(function() {         // scope of this now relates to a tags         $(this).hide('slow');     }); });
