Question

I am doing Ajax Call from View, then controller is fetching data from DB into an Array, now this array value I want to pass to JavaScript, so that I can update data in a table with different id’s

Controller code:

def AjaxView
 @var1 = Var.find(:all,:conditions => { :varname=> "one" },:select=> (params[:col]))
  respond_to do |format|
   format.js 
  end
end

AjaxView.js.erb code:

$(document).ready(function() {
   $("#test").text("valuetoupdate");
  });

Now when I run this code it successfully update “valuetoupdate” at id =test in view page.
Instead of this I want to update all values one by one from array @var1.

I searched more and realized that array @var1 generated in Controller will automatically get transferred to AjaxView.js.erb file. Now I have to iterate over all values, but this code doesn’t work in JavaScript file:

<% for var in @var1 %>
$("#3").text(var);
<% end %> 

it gives blank response

Thanks Guys,

I am able to resolve my issue, in following manner,
I moved away from for loop implementation, instead start using if else condition,

   <% if @var.to_s == 'valuetoupdate' %>
    { }
   <% elsif @var.to_s == 'valuetoupdate1' %>
    {}

And it worked fine for me.
