Other - Accessing parent window from child window?

I have a main window named worklistManager.jsp.
worklistManager.jsp has a pop up window named processManager.jsp.
Again, processManager.jsp has another pop up window, named eventLog.jsp.
Once again eventLog.jsp has a pop up window named eventUsers.jsp.

eventUsers.jsp has a dojox/grid/DataGrid and a button. After selecting a particular row in the grid, then clicking the button, it has to place the value into the textbox of eventLog.jsp after closing eventUsers.jsp.

So far, I have tried the script below to accomplish this, but it's not working as I hoped.

Code:

<script type="text/javascript">
        function getEventLogUserSelect(){
         if(dijit.byId('dynamiceventusergridCWUSER')){
         var selctedItem = dijit.byId('dynamiceventusergridCWUSER').selection.getSelected();
                 if(selctedItem.length){
                  dojo.forEach(selctedItem, function(selectedItem){
                  if(selectedItem !== null){
                  dojo.forEach(dijit.byId('dynamiceventusergridCWUSER').store.getAttributes(selectedItem), function(attribute){
                  var value = dijit.byId('dynamiceventusergridCWUSER').store.getValues(selectedItem, attribute);
                  if(attribute == "USERID"){
                  window.opener.SetValue(value);
                  window.close();
                  }
                  
                  });
                  }
                  });
                  //alert("grid row selected");
                 }else{
                  alert("grid row not selected");
                 }
         }
                if(gbshowgridFlag==false){
                 alert("grid not loaded");
                }
        }
        function SetValue(val){
                var txt = document.getElementById('CWPROCESSEVENTLOG.USER_ID');
                txt.value = val;
                
         }
        </script>

Look into HTML5 Web Storage; specifically sessionStorage. This will allow you to send variables, though session data, across multiply windows.

Another solution you might try would be to have another look at your SetValue() function. When you run this script, what are you getting in the console?

javascript Code:

Original - javascript Code
window.opener.SetValue(value);

window.opener.SetValue(value);

Seems odd. What if you called the function directly, without the window.opener in getEventLogUserSelect()?

javascript Code:

Original - javascript Code
if(attribute == "USERID"){ SetValue(value); }

if(attribute == "USERID"){
    SetValue(value);
}

Then, do all of your window.opener operations in the SetValue() function:

javascript Code:

Original - javascript Code
function SetValue(val){ var txt = window.opener.document.getElementById('CWPROCESSEVENTLOG.USER_ID'); txt.value = val; window.close(); }

function SetValue(val){
    var txt = window.opener.document.getElementById('CWPROCESSEVENTLOG.USER_ID');
    txt.value = val;
    window.close();
}

Of course I could be way off base here. Let us know how it goes.
