Hi,

I have a form where I’m adding multiple items. So I have an “Add New  
Item” link to the page. Here’s how I define it in the controller’s  
helper …

```
    def add_item_link(name)
            link_to_function name do |page|

```

page.insert\_html :bottom, :ec\_line\_items, :partial =\>  
“ec\_line\_item”, :object =\> EcLineItem.new  
end  
end

The link is invoked on the page like so:

\<%= add\_item\_link “Add an item” %\>

My question is, let’s say I want an additional javascript function,  
“myFunc()” to run after the above HTML has been inserted. How do I  
modify the helper function above to execute “myFunc()” after it has  
done its thing?

Thanks, - Dave

Try this:

def add\_item\_link(name)  
link\_to\_function name do |page|  
page.insert\_html :bottom, :ec\_line\_items, :partial =\>  
“ec\_line\_item”, :object =\> EcLineItem.new  
page \<\< “myFunc();”  
end  
end
