Rjs

Rails
1

I am playing with the new .rjs stuff in edge rails.
I am doing stuff like :
page.replace_html ‘scoops_tot’, @scoops.size

  1. I want to add my own javascript functions to the page object.
    Is it possible and how ?

  2. I am trying to update several fields, but i would like a to have a
    dekay between the updates :
    @anoclicks.each{|aclick|
    page.replace_html ‘click_number_’+aclick.scoop.id.to_s ,
    aclick.scoop.clicks_tot.to_i + aclick.scoop.anoclicks_tot.to_i
    page.visual_effect :Pulsate, “click_me_#{aclick.scoop.id}”
    }

Reading through the file*, I see this method which may be what you want:

Writes raw JavaScript to the page.

def <<(javascript)
@lines << javascript
end

You want something like this (from the book):

page.delay(3) do
page.alert @rails_version
end

which I’m sure you can adapt for your purposes.

Thank you for your answer
I have the book in front of me (the pdf of course)
I did not see this << method, but just found it in the last version of
the doc ! Great !

For the delay, i cannot get it working more than once.
I want to execute an effect for each item in an array and each time
apply the same delay… I am going to play with that << thing.

Thanks a lot :slight_smile:

I haven’t tried it, but it may be possible to nest delay blocks.

page.delay(3) do
page.do_something
page.delay(3) do
page.do_something_again
end
end

I found a solution that is working great :

i = 0
@hp.each{ |hp|
page.delay(i) do
page.visual_effect :Fade, ‘scoop_’+hp.id.to_s
i+=1
end
}

Thx for your help

More ruby-like:

@hp.each_with_index do |hp, index|
page.delay(index) do
page.visual_effect :Fade, “scoop_#{ hp.id }”
end
end
