I have a custom button on my Account object that uses OnClick Javascript to display a modal popup.  Currently in the Javascript, from that modal popup, the "Run Tool" button executes a VF page passing in the Account.Id.  I have a picklist on the modal popup with related Accounts.  What I need to do is pass the related Account Id that is selected in picklist into my Javascript to be able to execute my VF page for whatever Account Id is selected. The Related Account Ids are custom fields on the Account object.  I haven't had any luck finding an example of how to pass the picklist value from the child/modal popup back to the Javascript in the OnClick code.  Is this even possible?



OnClick Javascript

var j$ = jQuery.noConflict();
try{
  j$(function() {
    /*Append the jQuery CSS CDN Link to the Head tag.*/
    j$('head').append('<link rel="stylesheet" href="//ajax.googleapis.com/ajax/libs/jqueryui/1.10.3/themes/start/jquery-ui.css" type="text/css" />');
    
    /*Create the HTML(DIV Tag) for the Dialog.*/
    var html = '<div id="dialog" title="Select account to run"><p>Do you want to go to the Home tab ?</p></div>';
    
    /*Check if Dialog(DIV Tag) already exists if not Append same to the Body tag.*/
    if(!j$('[id=dialog]').size()){
      j$('body').append(html);
    }    

    var iframe_url = '{!URLFOR("/apex/ProductPenetrationPopup?id="+Account.Id )}'
    var tool_url = '{!URLFOR("/apex/ProductPenetration?id="+Account.Id )}'

    /*Open the jQuery Dialog.*/ 
    j$( "#dialog" ).html('<iframe id="iframeContentId" src="' + iframe_url + '" frameborder="0" height="100%" width="100%" marginheight="0" marginwidth="0" scrolling="no" />')
     .dialog({

      show: {duration: 10},
      hide: {duration: 10},
      buttons: {
        "Run Tool": function() {
         window.location = tool_url; /*currently runs Product tool using the Account.ID*/
          j$( this ).dialog( "close" );
        },
        Cancel: function() {
          j$( this ).dialog( "close" );
        }
      }
    });
  }); 
}
catch(e){
alert('An Error has Occured. Error: ' + e);
