Masterview users - Dec 2007 - conditionally hiding a tag and form_remote with parameter

Hi,

I''m trying to conditionally hide a div tag. The only way I could get it
working
is like this:

<div mv:if="!@open_tasks.empty?">

    *some html

*</div>

<div style=''display:none'' mv:else="">

*    same html*

</div>

However, I don''t like it, as I have to repeat the same html twice. Is
there
a
better way of doing it?

Another thing: Can I create a form_remote_tag with a parameter using
mv:form_remote? So far I only made it working using form_remote_tag
directly like this:

     {{{ form_remote_tag :html => { :id =>
''order_form_open''  } do}}}

But I obviously like to avoid this as it shows up on the page.

Kind Regards,
Nico

To conditionally set the a div to a style of hidden you can simply use
mv:attr

<div mv:attr=":style => #{(@open_tasks.empty?)  ? 
''display:none'' :  '' ''}">
  some html
</div>

basically just using an inline conditional to determine what to set the
style to
If you were wanting to do this a lot, then a custom directive could be
created to simplify the syntax.


As for the form_remote you can do something like this

<form mv:form_remote=":html => { :id =>
''order_form_open''  } ">
</form>

We haven''t updated the form directives to use the block style yet, but
the
above should do what you need.

Have a Merry Christmas!

Jeff
