Using jQuery end() function with Destructive methods

Question

I'm having some problems grokking the .end() function in jQuery. The docs I've read advertise it as "rolling back" changes from a filter or additional selection. For example,

var someDivs = $('div');
someDivs
  .filter('li')
  .css('color', 'green')
.end(); // ok, reverted back to original wrapper

On the other hand, this doesn't work.

someDivs
  .get(0) // get DOM element at index 0
.end(); // error, executing a jQuery method on a plain javascript object.

I'm just trying to verify that I'm correct that after certain chain-destructive methods like html(), text(), and get() are called, it's impossible to revert back to the original wrapper.

Thanks in advance.

Answer 1

Yes, end() will only work on methods that return a jQuery object. Methods that return strings (.html(), .text()) or DOM elements (.get()) won't allow you to chain any jQuery methods at all subsequently.
