How do I create unique IDs in a Dojo widget template?

阅读更多关于 How do I create unique IDs in a Dojo widget template?

问题 I have a Dojo widget that I'm writing that adds a label and an input box to the user's page. The for attribute of a label requires an HTML ID value, but a Dojo widget should not contain IDs in case multiple instances are created on the same page. So, does anyone have any suggestions on how to work around these conflicting needs? 回答1: Out the box, this is how the dijit registry sets WidgetID (this.id) if the configuration parameter is not present while constructing: constructor: function(args)

问题 I want to override dijit._CssStateMixin's domReady() method. Is there any way to override that instead of changing the listener mechanism in Dojo. I tried overriding _cssMouseEvent() method in simple javascript, but it still does invoke dijit's _cssMouseEvent() from domReady(). I have tried following approach: dojoConfig = { map: { 'dijit/_CssStateMixin': { 'dojo/domReady': 'app/noop' } } }; I have added 'app' folder and then 'noop.js' inside that. noop.js has nothing in it: define([],

阅读更多关于 How to force relative pathing with Struts 2.1 and Dojo?

问题 I upgraded from Struts 2.0.6 to 2.1.6 and converted all my Ajax themes to plugins. Everything works except the pathing has changed from relative to absolute. For example, here is the rendered HTML before upgrade: <script type="text/javascript" src="../struts/simple/dojoRequire.js"></script> And here it is after upgrade: <script language="JavaScript" type="text/javascript" src="/myApp/struts/ajax/dojoRequire.js"></script> Somehow the absolute "/myApp" is getting used instead of the relative ".
