Running dojo or javascript tookit on the SERVER side?

Thursday, February 14. 2008

If you are not familiar with .NET and the precious runat="server" or runat="client", have a look a at: http://www.aptana.com/jaxer

The idea is simple and very very practical. In some situations, you may want to run code on the server OR on the client. The problem with a lot of javascript frameworks is they do a LOT of work on the client side. What if we could make the server work a little harder?

Based on John Resig's work,

http://ejohn.org/blog/bringing-the-browser-to-the-server/

I convinced myself I could create a "template parser" for dijit widgets that would read the following tags:



<dijit:form:CheckBox id="cb" runat="server"/>



<dijit:form:CheckBox id="cb2" runat="client"/>

The first part was making sure that a dijit widget could be created on the server side.
Amazingly after some tweaks, this works:



C:\Utils>java -jar js.jar

Rhino 1.6 release 7 2007 08 19

js> load('env.js');

js> window.location = 'test.html';

test.html

js> var djConfig = {baseUrl: "Z:/GDECORE/js/OpenAjax/dojo/"};

js> load('Z:/GDECORE/js/OpenAjax/dojo/dojo.js');

js> dojo.require('dojo._base.html');

[object Object]

js> dojo.require('dijit.form.CheckBox');

[object Object]

js> var widget = new dijit.form.CheckBox({id: "cb", name: "cb"}, dojo.byId("test"));

js> print(dojo.body().innerHTML);

<div role='presentation' waiRole='presentation' class='dijitReset dijitInline dijitCheckBox' widgetId='cb'><input dojoAttachEvent='onmouseover:_onMous

e,onmouseout:_onMouse,onclick:_onClick' id='cb' class='dijitReset dijitCheckBoxInput' value='on' tabindex='0' type='checkbox' dojoAttachPoint='focusNo

de' name='cb'/></div>
