Dojo and CodeIgniter

Ajax, Codeigniter, Dojo

I finally found time to add my imRichEditor widget (a Dojo widget that integrates TinyMCE) to my demo site. I built my demo site using CodeIgniter and I had to figure out the best way to integrate/call the Dojo files.

Dojo vs JQuery, Part 2: Plugins, Widgets

Ajax, Dojo, dojo-widgets, JQuery, plugins

Not long after I begin learning a new Javascript Framework, I find a need to create a plugin (or widget). I have created quite a few JQuery plugins (see previous posts) and have recently created a my 4th Dojo Widget (I have also created a few YUI widgets). I recently began working on a  JQuery photogallery plugin (I know, why re-create the wheel). I actually created this photogallery quite a few years ago, but not as a JQuery Plugin, but as a Javascript object (class). I am now converting it into a JQuery plugin.

While working on a different project (that uses Dojo), I also had to create a photogallery. While I enjoyed the benefits of using both JQuery and Dojo to re-create the photogallery, I have to say that the ability to create a template (Dojo Widgets) can significanly decrease the time it takes to create a plugin or widget.

When I initially read about Dojo widget templates, I didn’t really understand the need. My perception was that if a developer was fairly proficient with creating and manipulating DOM elements, then what is the need for a template? Well, creating this plugin using both JQuery and Dojo gave me a more favorable perception of using templates – a tremendous advantage.

Although the requirements for the JQuery photogallery plugin was a bit more complex (and although I still find it easier in general to develop using JQuery), I have to say that having the ability to create a template gives Dojo a real advantage over JQuery when creating widgets or plugins.  Advantage: Dojo.

Dojo: Setting the Visibility Style Attribute on a Button Dijit

Ajax, Dojo, Pebblet

I ran into a problem the other day when trying to set the visibility style attribute on a Dojo button. I assumed that setting styles on a Dijit was similar to setting the style on any other DOM element:

?View Code JAVASCRIPT
dojo.style(node, style, value)

But setting styles on a Dijit does not work they one would expect. My original code:

?View Code JAVASCRIPT
var btn = dijit.byId('register_btn');
dojo.style(btn, {visibility:'visible'});

This did not work because ‘btn‘ is not a DOM node. After an hour or so of trying different ways to get the code to work, I finally tried:

?View Code JAVASCRIPT
var btn = dijit.byId('register_btn').domNode;
dojo.style(btn, {visibility:'visible'});

It worked. And it makes sense. I can further simplify it with:

?View Code JAVASCRIPT
dojo.style(dijit.byId('register_btn').domNode, {visibility:'visible'});

While I have accessed widgets (Dijits) using the domNode in the past, I just didn’t think that I would have to when using dojo.style. But it works, so I can move on.

Dojo: Adding Items to a Combobox Dynamically

Ajax, Dojo, Javascript

I was trying to fill a dijit.form.combobox dynamically without using ItemFileReadStore, but it has proven to be quite a challenge. I was trying to fill the combobox from an array. It appears that Dojo’s combobox does not inherit all the attributes of a regular HTML combobox. When using just Javascript to dynamically fill a combobox, I made use of the ‘options’ attribute:

Dojo and TinyMCE – Creating a Widget

Ajax, Dojo, dojo-widgets

I’m working on a project using Dojo which requires a wysiwyg editor that is more robust than Dojo’s Dijit.Editor. After doing a bit of research, I decided to use TinyMCE.  This wysiwyg editor is very robust, has great documentation and is the editor that WordPress uses. Integrating TinyMCE did not appear to be difficult, but I also wanted to create a TinyMCE Dojo widget, so that I could easily reuse TinyMCE in other Dojo projects without having to remember how to set it up.

Dojo – Changing Dialog’s Underlay Color

Ajax, CSS, Dojo, Pebblet

I read on dojocampus.org that the color of the Dialog’s underlay can be changed. The example on the site shows how to change the underlay color of an individual dialog box:

    #dialogColor_underlay {
        background-color:green;
    }
<div id="dialogColor" title="Colorful" dojoType="dijit.Dialog">
     My background color is Green
</div>

But, this only changes the underlay color of an individual dialog box. It seems to me that unless I am building an Dojo application for, let’s say a kid’s website, that I want the color change to be consistent. I also don’t want to have to create a separate style for each Dialog box that I may have on a page. So, to change the underlay color for all dialog boxes on a page:

.dijitDialogUnderlay {
     background: green;
}

Easy.

Dojo – Understanding The BorderContainer

Ajax, Dojo

I recently restarted a project that I haven’t worked on in nearly a year. I am using Dojo for the project. I ran the application in order view the current functionality and to try to figure out where I stopped in my development. I then upgraded to a new version (1.3) and viewed the website once again. I immediately noticed a firebug message that basically told me that the LayoutContainer was being deprecated and would not be used in version 2. The message also suggested that I should use BorderContainer instead.

Dojo: Setting Button Width via CSS

Ajax, Dojo, Pebblet

I am working on a project using Dojo and I wanted all the buttons in the application to have the same width. By default Dojo will set the width of the button by the width of the button label (the more characters in the label, the wider the button). To set all the buttons to the same width, I add the following to my CSS file:

?View Code JAVASCRIPT
.dijitButtonNode {
     width:150px;
}

Simple enough.
