Accessing loop counter ?

Any way to in CityScript:

1. write the loop counter (e.g. "current article number is" {$x$})

2. reference the total loop count (e.g. "total number of articles is:"...)

Something like this would be handy to allow separators.  If there were a way to test if this is the first or last record then you can conditionally include HTML to separate items.  My definition of a separator is something that doesn't appear before the first record or after the last record.

How about hard coding the first reference and then using a loop for all the others?

<hard coded link> {$foreach$} , <one>, <two>, etc.{$next$}

You can create a counter very easily using JavaScript. Here's how to present a count of the articles listed in an index:

1. Place a script block above the ForEach loop setting a counter variable to 0. The keyword "var" is optional but I add it when the variable is first initialized as a marker to myself.

  var loopCounter = 0;

2. At the beginning of the loop insert a script block to add 1 to the counter variable.

  loopCounter += 1;

3. After the loop insert a script block to display the count.

  document.writeln("The number of articles is: " + loopCounter");

Better still, place the first two script blocks into CityDesk variables.

I've updated the example on my website to include the loop counter. You can get it at:

My website is up but I am still working on the content. Feel free to check it out at:

The example cty file will be linked to the Tips page this weekend but you can download it using the direct link above.

CityDesk and JavaScript make a very powerful combination.
