HTML Templating with Handlebars Conditionals

[former_member189945]

Hi all,

Is it somehow possible to use Handlebars Conditionals with SAPUI5 HTML Templating? My problem is that I would like to define a Block in view which would be shown only if a value in a JSONModel is true.

I cannot find any mention about Handlebars Block Helpers in the SAPUI5 documentation besides "#each" helper. I tried to use "#if" similarly but it doesn't work.

Here's a jsbin:

And here's a link to Handlebars documentation about Block helpers:

http://handlebarsjs.com/block_helpers.html

Hi Kimmo,

I think the handlebars template is still under construction, and only supports the rendering of each, looking in the comments of 1.22.4, it had a TODO comment next to with, if and and unless.

Many thanks,

Jason

  // TODO: implement support for "if", "unless", "with", ...

  // extended helpers:

  //   - each

  //   - with   (TODO)

  //   - if     (TODO)

  //   - unless (TODO)

  // custom helpers:

  //   - control: allows to declare a UI5 control

  //   - element

  //   - attribute

  //   - property

  //   - aggregation

Hi Jason,

Thanks for the info and for looking that up. So we just have to wait for updates to UI5.

Then, any idea of a scenario where templating would be useful as it is now? #each can be replaced with aggregation bindings, can't it.

Hi Kimmo,

You can use for creating controls etc, looks like it's the block helpers that are still to be implemented.

Many thanks,
