Jinja and javascript syntax syndrome?

I am using janja2 templating language in my GAE-python project. I tried using jquery-upload to upload files.

The following code throws an error:

<!-- The template to display files available for upload -->¬
    152 <script id="template-upload" type="text/x-tmpl">¬
--  153     {% for (var i=0, file; file=o.files[i]; i++) { %}¬
|   154     <tr class="template-upload fade">¬
|   155         <td class="preview"><span class="fade"></span></td>¬
|-  156         <td class="name"><span>{%=file.name%}</span></td>¬

The above code is directly taken from the jquery download library.

Error:

line 153, in template
    {% for (var i=0, file; file=o.files[i]; i++) { %}
TemplateSyntaxError: expected token ')', got 'i'

I think it is called due to {% %}which jinja2 is used, as well as the text / x-tmpl js syntax. It's right? If so, how can I get around this? Please, help.

Try the following:

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

Or you can use the blocks {% raw%} {% endraw%}.
