ColdBox JQueryUI Plugin

Fri, 07 May 2010 14:00:00 +0200

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:


jQueryUI = getPlugin("JQueryUI",true); 
jQueryUI.setEnableWidget('tabs');

...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.


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

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.


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);

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
Place this code somewhere in your layout file. This renders the output of the plugin. #getPlugin("JQueryUI",true).render()#

Enjoy!

IE auto content fit IFrame HACK

Sun, 05 Apr 2009 14:21:01 +0200

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:


	function autoFitIFrame(elementId){
		if (!window.opera && !document.mimeType && document.all && document.getElementById){
			parent.document.getElementById(elementId).style.height=this.document.body.offsetHeight+"px";
		}
		else if(document.getElementById) {
			// ErnestoZ HACK: if you call scrollHeight TWICE, the second value is the real height of the iframe
			var scrollHeightWrong = this.document.body.scrollHeight; 
			var scrollHeight = this.document.body.scrollHeight; 
			alert(scrollHeightWrong);
			alert(scrollHeight);
			parent.document.getElementById(elementId).style.height = scrollHeight+"px";
		}
	}

OFC-CFC: Open Flash Chart - Coldfusion CFC Library

Mon, 09 Mar 2009 17:48:19 +0200

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:

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

ColdDoc, created by Mark Mandel, ROCKS!

Sun, 08 Mar 2009 02:33:03 +0200

In case you missed it, check out http://colddoc.riaforge.org/

Another piece of magic by Mark Mandel. It creates docs of your cfcs in JavaDoc-style and most important, it shows inherited methods too!

WHOIS your Daddy?

Sun, 08 Feb 2009 17:46:47 +0200

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

Here's the code:



	
	

	
		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;

Some examples:



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

Railo CFVIDEOPLAYER 'borrowed' from JW FLV MEDIA PLAYER?

Fri, 12 Sep 2008 02:39:01 +0200

Railo doesn't mention anything on their site/blog about 'borrowing' the flv-player from Jeroen Wijering.

So please let me know if you see any difference between these flv-players:

ColdBoxProxy and JSON

Sun, 24 Aug 2008 16:32:00 +0200

If you work a lot with JSON and remote calls like me, the following coldboxproxy.cfc code could be handy for you.



	
		

			
				
				
		
				
				
					
					
					
					
					#getPlugin("JSON").encode(data:results,queryKeyCase:"upper")# 	
				
					
				

				#processException(cfcatch)#

The URL of your remote call will be something like this:

coldboxproxy.cfc?method=process&json&event=ehCompany.getCompanies

Find a letter on a position in the Alphabet

Fri, 22 Aug 2008 16:13:00 +0200

Just needed a quick way to find a letter in the alphabet on a postion.

So for example, postion 1 returns 'A' and position 26 returns 'Z'.

Step 1: Function

Step 2: Call function

#getAlphabetLetter(26)#

returns: Z

BOOKMARKS in Eclipse,OPENS frequently used FILES!

Thu, 21 Aug 2008 17:37:00 +0200

Just stumbled upon on article of Luis de la Rosa which explains how to use bookmarks in Eclipse to track important lines of code.

This feaure is really handy for fast opening frequently used files in Eclipse e.g. Transfer.xml.cfm or i18n files.

Am I the only one who never used bookmarks in Eclipse before?
