Select Tag in JSP with multiple="true"

<s:select name="mylist" id="id_mylist" list="countryList" multiple="true"/>

On submit of the form calling the following Java Script. This will essentially mark all the element in the list as selected.

function doSubmit(){
 var mylistvar =document.getElementById("id_mylist");        
             if(mylistvar  !=null){      
                for(var x=0;x<mylistvar.options.length;x++){        
                    mylistvar.options[x].selected=true;
                }
             }

}

The ArrayList variable used above could looks like this.

private ArrayList<String> countryList = new ArrayList<String>();

This way when the form is submitted all the values in the list would be bind to the server directly as an arraylist.
