ColdBox JQueryUI Plugin

I work quite a lot with JQueryUI 1.8 lately, so time has come to create a new CB plugin. The JQueryUI Plugin handles (core)JS dependencies and CSS links for you, so no CFHTMLHEADs in your views anymore to include the proper files. You can just write:

<cfscript>
jQueryUI = getPlugin("JQueryUI",true);
jQueryUI.setEnableWidget('tabs');
</cfscript>

...or to enable multiple widgets at once:

jQueryUI.setEnableWidgets('tabs,datepicker');

What about effects and adding different ones along your code? Well, you can keep adding them and the plugin handles the boring stuff for you.

<cfscript>
jQueryUI.setEnableEffect('bounce');
// other code
jQueryUI.setEnableEffects('bounce,blind');
// other code
jQueryUI.setEnableEffect('explode');
</cfscript>

Adding interactions is rather simple as well. The following enables 'droppable and sortable' and includes the proper core JS files for you.

jQueryUI.setEnableInteractions('droppable,sortable');

What if you only need one specific core file only?

jQueryUI.setEnableCore('ui.position');

If you want to know which effects/widgets are supported by the plugin, you could use CFDUMP e.g.

Ok, we're almost done. What if you want to add your own CSS file which overrides style definitions from the core CSS?

jQueryUI.setCustomCssLink('includes/css/mytabs.css');

...which is exactly the same as:

jQueryUI.setCustomCssLink(href='includes/css/mytabs.css',media='screen',renderPosition=arrayLen(jQueryUI.getCustomCssLinks()));

As you noticed in the code above, we used an attribute 'renderPosition'. this attribute gives you control over the order how the CSS links are rendered. Having control over the rendering order is rather important for JS files (Thanks bro Tom de Man for notifying......or 'G. Ramsey' for the insiders). So let's say you have a couple of JS files which you're adding along your code and you want the last JS file being rendered as first.

<cfscript>
jQueryUI.setCustomJsLink('includes/js/myfile1.js');
jQueryUI.setCustomJsLink('includes/js/myfile2.js');
jQueryUI.setCustomJsLink(src='includes/js/myfile3.js',renderPosition=( arrayLen(jQueryUI.getCustomJsLinks() )-1 ));
jQueryUI.setCustomJsLink(src='includes/js/myfile4.js',renderPosition=2);
// first position
jQueryUI.setCustomJsLink(src='includes/js/myfile5.js',renderPosition=1);
</cfscript>

Ok, all features discussed. Still interested?...let's set everything up.

Grab the JQueryUI plugin from RIAForge and place it into your plugin folder
Download jqueryui 1.8.1, unzip it into your includes folder (See screenshot below)
Add the following lines to your coldbox config file

<setting name="JQueryUIPlugin.baseRelativePath" value="includes/jQueryUI" />
Place this code somewhere in your layout file. This renders the output of the plugin.
<cfoutput>#getPlugin("JQueryUI",true).render()#</cfoutput>

Enjoy!

IE auto content fit IFrame HACK

Posted At : April 5, 2009 2:21 PM | Posted By : Ernst van der Linden

I ran into 'another' strange IE-browser behavior yesterday. It took me an hour of two to solve this iframe-height-problem.

If you call this.document.body.scrollHeight in an iframe twice, the first value is wrong, but the second value is okay.

Look at the example below:

OFC-CFC: Open Flash Chart - Coldfusion CFC Library

Posted At : March 9, 2009 5:48 PM | Posted By : Ernst van der Linden
Related Categories: ColdBox,Coldfusion

I just released version 1.0 of OFC-CFC on Google Code.

OFC-CFC is a Coldfusion CFC Library which produces JSON-data for Open Flash Chart version 2.0

The real power of Open Flash Chart is, you can update charts using JSON-data. Which means. update your charts using e.g. JQuery or Spry, without reloading a page.

So you can create charts like:

barchartAnimated

Please let me know if you have any questions or remarks.

What do you think...? MySQL Toad

I just came across Toad for MySQL

Please let me know if you think it's worth a try and if it's a good replacement for MySQL WorkBench (which contains more bugs after every update!)

WHOIS your Daddy?

Posted At : February 8, 2009 5:46 PM | Posted By : Ernst van der Linden

I was playing around with querying a whois server. Actually I didn't know it was that easy...

Here's the code:

<cffunction name="getWhoisData" access="public" returntype="string" hint="I return data from a whois server">
    <cfargument name="whoisQuery" type="string" required="true" hint="e.g. 'domain microsoft' or '?' to show whois server help-commands">
    <cfargument name="whoisServer" type="string" required="false" hint="e.g. whois.ripe.net. Default server is whois.internic.net">

    <cfscript>
        var whoisData = '';
        var whoisClient = createObject("java","org.apache.commons.net.WhoisClient");

        // use default whois server?
        if ( not isDefined("arguments.whoisServer") ){
            arguments.whoisServer = whoisClient.DEFAULT_HOST;
        }

        try {
            whoisClient.connect(arguments.whoisServer);
            whoisData = whoisClient.query(arguments.whoisQuery);
            whoisClient.disconnect();
        } catch (Any exception) {
            whoisData = exception.message;
        }

        return whoisData;
    </cfscript>
</cffunction>

Some examples:

<cfoutput>
    <h1>? [whois.internic.net]</h1>
    <pre>#getWhoisData('?')#</pre>
    <h1>domain microsoft.com [whois.internic.net]</h1>
    <pre>#getWhoisData('domain microsoft.com')#</pre>
    <h1>=microsoft.com [whois.internic.net]</h1>
    <pre>#getWhoisData('=microsoft.com')#</pre>
    <h1>registrar TUCOWS INC. [whois.internic.net]</h1>
    <pre>#getWhoisData('registrar TUCOWS INC.')#</pre>
    <h1>-G -B 192.113.224.88 [whois.ripe.net]</h1>
    <pre>#getWhoisData('-G -B 192.113.224.88','whois.ripe.net')#</pre>
</cfoutput>
