I am a newbie to javascript. I am experimenting with the below code for retrieving cross site data.

How can I do this code work, e.g. I want each family member is alerted to the screen.

Thank you for your help.

The code is amended like this and the alert says [object Object], do you know what this means??:

<html>
<head>
<script type="text/javascript" 

src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script type="text/javascript">

      // LOOP THROUGH EACH FAMILY MEMBER AND DO STUFF!
      alert(mValue)
    });
}
});
</script>
</head>
<body>
</body>
</html>

    you don’t want to wrap the oData with jQuery in your $.each

    so, instead of

    $.each($(oData['ops:patent-family']['ops:family-member']),

    you want:

    $.each(oData['ops:patent-family']['ops:family-member'],

    Also – you have to go down a level with the returned json (there is a first ‘ops:world-patent-data’ level), which will look something more like:

    if(oData['ops:world-patent-data'] && 
  oData['ops:world-patent-data']['ops:patent-family'] && 
  oData['ops:world-patent-data']['ops:patent-family']['ops:family-member']){

  $.each(oData['ops:world-patent-data']['ops:patent-family']['ops:family-member'],
    function(iIndex, mValue) {
      // LOOP THROUGH EACH FAMILY MEMBER AND DO STUFF!
      console.log(iIndex, mValue)
    });

}

    Another completely different way to do this is by using jquery deferreds syntax and using .pipe to transform the data – might be a bit cleaner than the if

    var sUrl =  "http://ops.epo.org/2.6.2/rest-services/family/publication/docdb/EP.1000000.A1/.js?callback=?";    

$.getJSON(sUrl)
.pipe(function(data){
    try{
        return data['ops:world-patent-data']['ops:patent-family']['ops:family-member'];
    } catch(e){
        return [];
    }
})
.then(function(members){
    $.each(members, function(iIndex, mValue){ 
        console.log(iIndex, mValue)
    })
})
