CRM2011 Unable to retrieve Lookup Filter selected Values in Javascript

Question

Here is the scenario:

1. I have added a ribbon button on contact Form. On clicking, it loads a modal dialog as shown below:

2. When I click on custom lookup icon button on modal dialog, I launch Lookup Filter Window using code below:

function OpenLookup() {

    var objectCode = "2";

    var url = serverURL+"/_controls/lookup/lookupinfo.aspx? AllowFilterOff=1&DefaultType=1&DefaultViewId={A9AF0AB8-861D-4CFA-92A5- C6281FED7FAB}&DisableQuickFind=0&DisableViewPicker=0&LookupStyle=single&ShowNewButton=1&Show PropButton=1&browse=false&currentObjectType=2&currentid={7D2D14AE-7EE1-E311-B136- 00155D02101E}&objecttypes=1%2c2";

    var lookUp = window.open(url, null,  "width=500,resizable=1,height=400,menubar=0,status=1,location=0,toolbar=0,scrollbars=1",  null);
    if (lookUp != null) {
        var selectedVal = lookUp.items[0].name;

    }
}

When I parse the resultant object lookUp , it does not have any variable items . So I am unable to retrieve selected values in lookup filter window.

Any help would be appreciated.

Thanks.

Answer 1

Here is how I do it:

 var UpdatedAccountId;
 var UpdatedAccountName = "";
 var lookUp = window.showModalDialog(url, "entity", "dialogwidth: 450; dialogheight: 300; resizable: yes");         
 var updated = JSON.parse(lookUp);

for (i = 0; i < updated.items.length; i++) {
    if (updated.items[0].id != null) 
     {
            UpdatedAccountId = updated.items[0].id;       
     }
    if (updated.items[0].name != null)
     {
           UpdatedAccountName = updated.items[0].name;         
     }
    }
