A reader pinged me yesterday with a simple problem that I thought would be good to share on the blog. He had a query of events that he wanted to use with jQuery UI's Accordion control. The Accordion control simply takes content and splits into various "panes" with one visible at a time. For his data, he wanted to split his content into panes designated by a unique month and year. Here is a quick demo of that in action.
I began by creating a query to store my data. I created a query with a date and title property and then random chose to add 0 to 3 "events" over the next twelve months. I specifically wanted to support 0 to ensure my demo handled noticing months without any data.

03.

<cfscript>
05.
q = queryNew("date,title");
06.
for(i=1; i<12; i++) {
07.
//for each month, we add 0-3 events (some months may not have data)
08.
toAdd = randRange(0, 3);
09.
10.
for(k=0; k<toAdd; k++) {
11.
newDate = dateAdd("m", i, now());
12.
queryAddRow(q, {date:newDate, title:"Item #i##k#"});
13.
}
14.
}
15.
</cfscript>
To handle creating the accordion, I had to follow the rules jQuery UI set up for the control. Basically - wrap the entire set of data in a div, and separate each "pane" with an h3 and inner div. To handle this, I have to know when a new unique month/year "block" starts. I store this in a variable, lastDateStr, and just check it in every iteration over the query. I also need to ensure that on the last row I close the div.

23.
<cfifthisDateStr neq lastDateStr>
24.
<!--- We only 'close' a div if not on the first iteration --->
25.
<cfifcurrentRow neq 1>
26.

<cfsetlastDateStr= thisDateStr>

42.
</cfif>

And the end result:
So, not rocket science, but hopefully helpful to someone. Here is the entire template if you want to try it yourself.
