Iterating without generating html elements

[Jeff Schnitzer]

I want to generate some templated json/javascript on a page. It
requires iterating; basically I want to generate the blahs in:

var foo = [ blah, blah, blah, blah ];

Is this possible with cambridge? I can iterate and generate html
elements, but it's not obvious how to do this without adding the html.

Thanks,
Jeff

This is possible with hidden tags. Any tag can be hidden by adding a:hide attribute so you can have something like the following:

var foo = [ <span a:foreach="foo" a:as="bar" a:hide>$bar</span> ];

a:hide makes the tag itself hidden from the rendered output, so it doesn't matter if the tag is a <span>, <foo> or <bar> it will be all the same. There is also the <a:span> tag, which is a dynamic tag that is hidden by default. With <a:span> it requires less typing:

var foo = [ <a:span foreach="foo" as="bar">$bar</a:span> ];

I hope this helps.

Great! That is exactly what I was hoping for.
