JavaScriptMVC 3.0

Explore the innovative design of JavaScript MVC 3.0, focused on modularity and efficient testing. This framework allows developers to create self-contained plugins that can be easily assembled into larger projects. Key features include seamless integration with jQuery, organized directory structures, and support for multiple templating engines. The framework also simplifies testing through FuncUnit, providing better async handling and more accurate event simulation. Drag-and-drop events are supported, enhancing interactivity while maintaining a small footprint for plugins.

  1. JavaScriptMVC 3.0 For Your Consideration

  2. GOALS • Make everything work without everything else • Move Test, Compression, Documentation into another project (can be used w/o jQuery) • Make VC parts close to jQuery.

  3. Directory Structure • Organized around a plugin • Can be hierarchical (jupiter/autocomplete) • Designed to enable building and testing self contained plugins then assemble them into a final project. • autocomplete folder – the plugin’s folder. • jmvcfolder – testing, docs, compression • jquery folder – jquery, and jqueryplugins

  4. Controller/Plugin • Extendable, but w/o a class system • Events auto attached via event delegation • Setup / teardown • Modify properties • State in ‘this’ • Small footprint – 70 lines $.plugin(‘autocomplete’, { setup : function(el, options){…}, teardown : function(el){…}, “input keypress”: function(el){…}, defaultText : function(newDef){…} }) //create $(“.search”).autocomplete(options); //access properties $(“.search”).autocomplete(“defaultText”, ”type here”); //destroy $(“.search”).autocomplete(“teardown”); //extend $.autocomplete.extend({ … })

  5. View • Renders using a JavaScript Template engine. • Multiple Engine Support • Can be compressed into plugin. • “Plugged into” append, prepend, html, text, etc. //draw in results dropdown when creating $.plugin(‘autocomplete’, { setup : function(el, options){ el.append(‘autocomplete/results.ejs’, options); }, … }) //create $(“.search”).autocomplete({loadingText: “loading …”}); //autocomplete/results.ejs <div class=‘dropdown’> <div class=‘loadingText’> <%= loadingText %> </div> <div class=‘results/> </div>

  6. FuncUnit Testing • Selenium / QUnit / jQuery syntax hybrid. • Works without selenium • Handles async without stop / start. • More accurately simulates browser events than selenium. • Plugins can add ‘test’ plugins similar to jquery: S.fn.autocomplete = module(“autocomplete") test(“Shows List", function(){ //loads page S.open("test/funcunit/autocomplete.html"); //types jquery aw in input S(“.search input").type(“jquery aw") //gets the text from the first result S(“.result:eq(1)").text(function(text){ equals(test, “jqueryawesomeness”,”it’s awesome”) }) })

  7. Drag-drop events • Support drag-drop events through bind and live • Set options on callback parameters or through event data. $(‘.handler’).live( “dragstart”, {distance: 5}, function(ev, drag){ if($(this).text() == “up”){ drag.axis(‘y’) }else{ drag.axis(‘x’) } } }) //Can be done with plugin like: “.handler dragstart({distance: 5})” : function(el, ev, drag) { … }
