Mixing static strings with NVelocity variables
July 14, 2009 by Daniel HoelblingIn an ongoing effort to get into NVelocity while programming the iC-Website I wanted to concatenate a filename with the current loop count variable:
<img src="/Content/images/dummy$velocityCount.png" alt="post-image" />
This isn’t working. You’ll end up with dummy$velocityCount.png. While I’d like it to result in dummy1.png.
I suspected it could be solved somehow by using our beloved angle bracket to tell NV to explicitly evaluate my text:
<img src="/Content/images/dummy{$velocityCount}.png" alt="post-image" />
This will result is dummy{1}.png, why is beyond me but NV will parse it. Still this doesn’t really work so I found the solution on how to explicitly invoke NV evaluation in the NV users guide:
<img src="/Content/images/dummy${velocityCount}.png" alt="post-image" />
This is nothing really new, it’s all laid out in the NV users-guide, still especially the second case made me scratch my head for a moment.
