Hi!

Im trying to search through multiple parameters through observe\_field.

Following is my code.: its not showing any result, kindly help…

Filter on Device Name :   
  
Filter on platform :

\<%= image\_tag(“spinner.gif”,  
:align =\> “absmiddle”,  
:border =\> 0,  
:id =\> “spinner”,  
:style =\>“display: none;” ) %\>

\<%= observe\_field ‘search’, :frequency =\> 2,  
:update =\> ‘table’,  
:before =\> “Element.show(‘spinner’)”,  
:success =\> “Element.hide(‘spinner’)”,  
:url =\> {:action =\> ‘trackLocation’},  
:with =\> “‘search=’+ escape($(‘search’).value) + ‘&search1=’ +  
escape(value)”%\>

\<%= render :partial =\> "devices\_list" %\>

and controller looks like:

def trackLocation  
@labs=Labt.find(:all)  
conditions = [“name LIKE ?”, “%#{params[:query]}%”] unless  
params[:query].nil?

@devices=Dev.find(:all,:conditions=\>[“name LIKE ? and platform LIKE ?”,  
“%#{params[:search]}%”,“%#{params[:search1]}%”]).paginate  
:per\_page=\>5,:page=\>params[:page]

#devs\_per\_page=5  
#@devs\_pages, @devs = paginate :devs, :conditions =\> conditions,  
:per\_page  
=\> devs\_per\_page

if request.xml\_http\_request?  
render :partial =\> “devices\_list”, :layout =\> false  
end

## end

Hi…

try the following…

\<%= observe\_field ‘search’, :frequency =\> 2,  
:update =\> ‘table’,  
:before =\> “Element.show(‘spinner’)”,  
:success =\> “Element.hide(‘spinner’)”,  
:url =\> {:action =\> ‘trackLocation’},  
:with =\> “‘search=’+ escape($(‘search’).value) + ‘&’ +  
‘search1=’+  
escape(value)”%\>

You can pass the value of the element you are observing. what do u mean  
by escape(value)?
