Hi everyone
I´know that it is not a ajax forum, but Im using ajax ina program
created with rails code and I think that I´m not the unique person who
use the Ajax. UpdaterPeriodically.
My problem is that my program doesn´t refresh the div tag, following
it´s my source code. Anyone can say me why it doesn´t work?
<head>
<%= javascript_include_tag ''prototype'' %>
</head>
<script type="text/javascript">
{
new Ajax.PeriodicalUpdater(imagen,
''image_tag("/guarrada/guarrada/foto.jpg")'',{frequency:''1''});
}
</script>
<h1>HOLA MUNDO</h1>
<%= link_to "My blog", posts_path %>
<p><%=image_tag("/guarrada/guarrada/foto2.jpg")
%></p>
<div id="imagen">
<%=image_tag("/guarrada/guarrada/foto.jpg") %>
</div>
THANKS!!!!

Anyone can say me why it doesn´t work?Well first off that image_tag isn''t in a <%= %> so that ruby won''t get evaluated. Additionally that second paramter should be the path to something on your server that will return an html fragment Fred> > <head> > <%= javascript_include_tag ''prototype'' %> > </head> > <script type="text/javascript"> > { > new Ajax.PeriodicalUpdater(imagen, > ''image_tag("/guarrada/guarrada/foto.jpg")'',{frequency:''1''}); > } > > </script> > <h1>HOLA MUNDO</h1> > <%= link_to "My blog", posts_path %> > <p><%=image_tag("/guarrada/guarrada/foto2.jpg") %></p> > <div id="imagen"> > <%=image_tag("/guarrada/guarrada/foto.jpg") %> > </div> > > THANKS!!!! > -- > Posted viahttp://www.ruby-forum.com/.-- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

But if the thing that I wanna to refresh it´s the image, how can I put it like a path to my server? My idea is refresh the image every second because is an image from an specific camera.

This is what you want:
<%= periodically_call_remote(
:frequency => 1,
:url => { :action => ''action'' },
) %>
When the action is called it will look for an RJS file with the same
name.rjs.
in the rjs:
page[:div].replace_html :partial => '' html piece with the
picture''

How can I do to refresh >> only that image >> > You need to write an action that only renders that div > > FredHi everyone: I have had sucess with Ajax.periodicallyupdater but the result weren´t be the expected, because I need to refresh the div with a frequency of 0.5 sec and with that frequency didn´t work like I need. Can you give another idea about functions or other ajax and rails functionalities for do that??
