The document discusses best practices for building robust jQuery plugins, including testing plugins with QUnit, implementing plugins by extending jQuery's prototype, releasing plugins with documentation and examples, and maintaining plugins over time by tracking issues and communicating with users.

1. Building Robust jQuery Plugins

2. Why bother?

4. Don't reinvent the wheel

5. “ Given enough eyeballs, all bugs are shallow ” -- Eric S. Raymond

6. Infrastructure

7. Design

8. Consider the audience

14. Test-driven development

17. Tests first

18. Behaviour-driven developement

19. Why bother?

20. QUnit

21. test("my ajax code", function() { expect(1); stop(); $.get("myurl", function(response) { equals(response, "expected response"); start(); }); });

22. Implementing

23. (function($) { $.fn.plugin = function() { return this.each(function() { // your code here }); }; })(jQuery);

24. (function($) { $.fn.delegate = function(type, delegate, handler) { return this.bind(type, function(event) { var target = $(event.target); if (target.is(delegate)) { return handler.apply(target, arguments); } }); }; })(jQuery);

25. (function($) { $.fn.plugin = function(settings) { settings = $.extend({}, $.plugin.defaults, settings); return this.each(function() { // your code here }); }; $.plugin = { defaults: {} }; })(jQuery);

35. Release

36. jquery.plugin-1.2.3.zip - jquery-plugin-1.2.3 jquery.plugin.js jquery.plugin.min.js jquery.plugin.pack.js - demo [-docs] [-test]

37. <target name=&quot;tooltip&quot;> <antcall target=&quot;generic&quot;> <param name=&quot;name&quot; value=&quot;tooltip&quot; /> </antcall> </target> ant tooltip

38. 1.3 --- * Added fade option (duration in ms) for fading in/out tooltips; IE <= 6 is excluded when bgiframe plugin is included * Fixed imagemaps in IE, added back example * Added positionLeft-option - positions the tooltip to the left of the cursor * Remove deprecated $.fn.Tooltip in favor of $.fn.tooltip 1.2 --- * Improved bodyHandler option to accept HTML strings, DOM elements and jQuery objects as the return value * Fixed bug in Safari 3 where to tooltip is initially visible, by first appending to DOM then hiding it * Improvement for viewport-border-positioning: Add the classes &quot;viewport-right&quot; and &quot;viewport-bottom&quot; when the element is moved at the viewport border. * Moved and enhanced documentation to docs.jquery.com * Added examples for bodyHandler: footnote-tooltip and thumbnail * Added id option, defaults to &quot;tooltip&quot;, override to use a different id in your stylesheet * Moved demo tooltip style to screen.css * Moved demo files to demo folder and dependencies to lib folder * Dropped image map example - completely incompatible with IE; image maps aren't supported anymore
