Counting the no. of iterations

Hi
I have a presentation template. And there is only one iw_iterate tag inside it.
How can I get the total no. of times the iw_iterate element will be run , i.e. how many times the item has been iterated in the dcr?I have to store that count in a variable say 'x'.
Then this variable will be used in a javascript code written inside SCRIPT tags in the PT itself.

You can use one of the attributes of tag called iteration. It gives you the number of iteration inside the tag e.g.

[HTML]

process each value

to get the count
[/HTML]

which will give you output something like:
1. abc
2. def

Other way is to use some perl coding inside. Like to get the count of total number of items under a replicant you can use:

[HTML]
my @list=iwpt_dcr_list('dcr.x.y');
my $count = scalar(@list);

[/HTML]

I've not tested the code. But It should work with some twisting on your side.

There is a million ways of doing so in a {iw_perl}-tag as the other posters remarks.

However, I always find it more robust to let the javascript find out him/herself how many items there are in the html-code.

Could you please be a little more explicit ! I didnot understand where to add these lines !

Sorry, the tage disappeared in the post. e.g. you can add following lines:

< iw_perl >
   my @list = iwpt_dcr_list('dcr.x.y');
   my $count = scalar(@list);
< /iw_perl >
< SCRIPT > 
   alert('{iw_value name="$count"/}');
< /SCRIPT >

PS: Remoe the spaces that I've put in < tags >.

(I removed the spaces for you ;-)

Note - you don't need the scalar() piece - the fact that the left hand side is a scalar variable automatically puts @list into scalar context.

Thanks Ghoti. But when I had put the tags without spaces, it got disappeared Smiley Happy

Thanks Ghoti. But when I had put the tags without spaces, it got disappeared .

I've posted numerous times about how to fix that - it's not great, but it's not that difficult (search the forums for the information) - however, if putting the spaces there works for you feel free to keep doing so.
