RJS page question

Rails
1

Hey there I’m trying to test this condition in an RJS template

if page[‘search’].value == “somequerystring”

And it never returns true. Any ideas?

I’ve used page[‘element’] = value for setting a textbox in the past with
no problem. Not sure what checking the value would fail.

Thanks.

RJS templates are a bit misleading. They are produced server side and
don’t have access to the state of the client side. So you can’t test
on the value of something on the page in the RJS template itself.

You can render a JS conditional, or you can pass the value you are
interested in as a parameter to the call that invokes the RJS action.

_Kevin,

That makes good sense. If anyone else runs into this, here’s the syntax

page << “if($(‘search’).value == ‘#{session[:value]}’) {”

do stuff here

page << “}”

Thanks _Kevin.

I don’t know if it does exactly what you’re interested in, but it’s
pretty good in other cases for getting rid of that fairly ugly syntax
