Hi  
I have a code in view like below…Here I am using Control.modl  
windows

 Primary Assignee Group \<%= text\_field "dummy\_service\_desk\_ticket", "dummy\_primary\_assignee\_group", "size" =\> 30, :readonly =\> "readonly" %\>&nbsp;[Select](#pop_primary_assignee_group) Assignee \<%= text\_field "sd\_ticket", "primary\_assignee", "size" =\> 30, :readonly =\> "readonly" %\> [Select](#pop_primary_assignee)

```
 As you can see there are 2 Buttons 'Select'.When i click on the

```

first select a search UI comes in the modal window and the result of  
search is shown on the same popup window.And when i click on one record  
in the window its value will be set on the text field by javascript and  
its id goet to the hiddenfield.  
\<%= hidden\_field “sd\_ticket”, “primary\_assignee\_group\_id” %\>  
So my problem is when i click on the second select how can i get this  
value…I tried like  
\<%= puts $(‘sd\_ticket\_primary\_assignee\_group\_id’).value %\> But  
getting error.

Think about that: you’re trying to write some ruby code (ie that runs  
on the server) to access something that exists only on the browser.  
That can’t possibly ever work. In a chunk of javascript $F(‘some\_id’)  
will evaluate to the value of that input, $(‘some\_id’).setValue(123)  
sets the value.
