Two equally bad approaches to jQuery development (I think)

gistfile1.js

// I often find myself searching up the DOM tree with jQuery to access related items.  
// Say, each item is in a li and I need to toggle other elements in that li. 
// This usually takes the form of a blind man, counting floor tiles so he can find his way back,
// or similar.  Either way, it feels like bad form and is probably very ineffienct. 

// Solution A:  Tag each relevant markup item with a particular ID attribute that is used to lookup related elements
jQuery("a.edit-todo-link").click(function(e) {
	var todo_id = jQuery(this).attr('todo_id');
	var parent_container = jQuery('li[todo_id=' + todo_id + ']');

	parent_container.find('.edit-todo').css('display', 'inline');
	parent_container.find('a.todo-title').hide();
	
	e.preventDefault();
});
  
// Solution B:  Search up tree using closest, etc
jQuery("a.edit-todo-link").click(function(e) {
	var parent_container = jQuery(this).closest('li');

	parent_container.find('.edit-todo').css('display', 'inline');
	parent_container.find('a.todo-title').hide();

	e.preventDefault();
});
