onChange + javascript in perl CGI - question

Hello all,

Am trying to include a onChange java script to my perl CGI application which uses POST method to upload files to file_server

This is how I embedded javascript in the perl code that renders CGI application

Code:
print qq|
  <script type="text/javascript" src="display.js">
  </script>
  |;

Contents of display javascript are :

Code:
function changeDispatch(newLink) {
  if ( newLink != null ) {
    document.location.href = newLink;
  }
}

This is the popup menu, when an item is selected from the list it should automatically trigger the action designation instead of a separate "GO" ( submit ) button for each of the popup menu that I have got.

Code:
print $cgi->popup_menu(-name=>'fruits',
                         -values=>$fruits_arr,
                         -onChange=>"changeDispatch('$arg')");

Here in '$arg' if am able to store the selected value from the popup_menu, then its quite easy to formulate a string and pass it to changedDispatch in javascript.
But am not able to retrieve any such data

Whats happening :
If I click on any of the fruits say, "apple" the onClick effect is happening and it comes to the same initial page. If that is, fruits.cgi once I click that - it again comes to fruits.cgi as though it has been loaded for the first time

What I want to happen :
Based on the onClick event, I have other functions to be dispatched via GUI. That would seem to happen only when I know what option is clicked.

I accept that am not that good when it comes to GUI design or adding effects to that.

I have seen several website doing this, it should be something very easy for those who had already worked on this.
Could you please provide some pointers ?

thanks Smilie

HOBBIT-HOSTGRAPHS.CGI(1)				      General Commands Manual					  HOBBIT-HOSTGRAPHS.CGI(1)

NAME
hobbit-hostgraphs.cgi - CGI program to show multiple graphs SYNOPSIS
hobbit-hostgraph.cgi DESCRIPTION
hobbit-hostgraph.cgi is invoked as a CGI script via the hobbit-hostgraph.sh CGI wrapper. If no parameters are provided when invoked, it will present a form where the user can select a time period, one or more hosts, and a set of graphs. The parameters selected by the user are passed to a second invocation of hobbit-hostgraph.cgi, and result in a webpage showing a list of graph images based on the trend data stored about the hosts. If multiple graph-types are selected, hobbit-hostgraph.cgi will display a list of graphs, with one graph per type. If multiple hosts are selected, hobbit-hostgraph.cgi will attempt to display a multi-host graph for each type where the graphs for all hosts are overlayed in a single image, allowing for easy comparison of the hosts. The hostlist uses the PAGEPATH cookie provided by Xymon webpages to select the list of hosts to present. Only the hosts visible on the page where hobbit-hostgraph.cgi is invoked from will be visible. The resulting graph page can be bookmarked, but the bookmark also fixates the time period shown. OPTIONS
--env=FILENAME Loads the environment defined in FILENAME before executing the CGI script. BUGS
This utility is experimental. It may change in a future release of Xymon. It is possible for the user to select graphs which do not exist. This results in broken image links. The set of graph-types is fixed in the server/web/hostgraphs_form template and does not adjust to which graphs are available. If the tool is invoked directly, all hosts defined in Xymon will be listed. SEE ALSO
