Note: you don't need to use createTiddlyElement(...) to produce output
from embedded inline javascript. Simply return a TEXT value, and it
will be automatically 'wikified' and rendered where the script is
embedded. In your suggested script, since 'cnt' is a numeric value,
you would write:
return cnt.toString();
Also, the technique of looking for all checkboxes contained with
{{count{...}}} is not sufficient: suppose you have rendered several
different tiddlers, each with checkboxes wrapped in {{count{}}}. In
that case, jQuery would find the checkboxes in all the rendered
tiddlers, not just the current one.
Fortunately, since you are using InlineJavascriptPlugin, there is an
alternative: The 'place' variable, which is automatically defined by
the plugin for use within scripts, can be used to make *relative*
references to the last element rendered into the current tiddler
(i.e., 'place.lastChild'), like this:
{{count{...}}}<script>
var a=jQuery(place.lastChild).find('.chkOptionInput')
var c=0;
for (var i=0; i<a.length; i++) c+=a[i].checked?1:0;
return c.toString();
</script>
Note: for place.lastChild to refer to the {{count{...}}} element, it
must be rendered *immediately* before the inline script (with NO
intervening content... not even whitespace).
You can also place the above script into a tiddler (e.g.,
[[CountCheckmarks]]) and then transclude it, like this:
{{count{...}}}<<tiddler CountCheckmarks>>
Important note: when using transclusion, the script is automatically
wrapped inside a containing DIV. As a consequence, the relative
reference to
place.lastChild
in the first line of the script needs to be changed to
place.parentNode.lastChild
like this:
var a=jQuery(place.parentNode.lastChild).find('.chkOptionInput')
