how can i add the for-loop index to the upload templ-form?

<script id="template-upload" type="text/html"> {% for (var i=0, files=o.files, l=files.length, file=files[0]; i {%=file.name%} {%=i%} > > the last line doesnt either work at all or the whole form breaks. how can i get the loop-index ? > > thx

The template will be rendered for each add call.
As long as the option singleFileUploads is set to true (which is the default), multiple selects/drops get split up into single add calls, so the index will always be 0.

From the JavaScript Templates documentation:

Note that the JavaScript Templates engine prints falsy values as empty strings.
That is, undefined, null, false, 0 and NaN will all be converted to ''.
To be able to print e.g. the number 0, convert it to a String before using it as an output variable:

<h3>{%=0+''%}</h3>

That is why the following won't print anything:

{% for (var i=0, files=o.files, l=files.length, file=files[0]; i<l; file=files[++i]) { %}
{%=i%}
{% } %}

hi and thx for taking the time looking into it. i took your advise and
chaged the options, and this was the only way i worked to build the form,
all other ways of supplying ended up in NOT shwoing the uploadform at all
(the list of files)
$('#fileupload').fileupload();

$('#fileupload').fileupload(
'option',
'singleFileUploads', 'false'
);

BUT, this still shows an index of 0:

{%=file.name%}

{%=i+''%}

so, no idea waz wrong here, i never used js-templates etc...

any ideas?

thx
