I'm using e.force:navigateToURL for clickable links in my lightning component. I have tried several different ways of creating this url. I need it to open the links in a new tab so that the original window remains open. 

When the links are clicked, it opens the URL in a new window (as expected), but it's also changing the original window's URL. How do I prevent this from happening?

Here is my function:
 

handleClick : function(component, event, helper) {  
        var baseURL = component.get("v.cbaseURL");
        var viewRecordEvent = $A.get("e.force:navigateToURL");
        viewRecordEvent.setParams({             
             "url": window.open(baseURL+'/'+ event.target.id,'_blank')              
       });
       viewRecordEvent.fire();
    }

Here are some screenshots showing the behavior.

Hi,

 I am working on one of the requirement where I am receiving JSON string in the response. I am confused whether to use JSON Parser or JSON Deserialization. Can someone provide some details about these 2 methods to extract the value from JSON string. 

Thanks,
