Unable to retain URI parameterswhen the page loads

Hello,

I have to pass the query parameters from one page to other on click of a button. Which I am doing as:

window.open(window.location.origin + "/xyz/WebContent/index.html?fName="+fname+'&Lname='+lname);

The page gets opened up in a new tab, however the url dosen't show up as it should have been.

Required URL-  http://myhost:0010/xyz/WebContent/#forward?fName=Cherry&Lname=Jon

but I am getting the URL as,

http://myhost:0010/xyz/WebContent/#forward

Due to which, I am unable to retrieve the parameters in this page.

For retrieveing parameters I am using :

var abc = jQuery.sap.getUriParameters().get("fName");

While debugging I am getting abc as null.

That means URI parameters are not coming.

Suggestions are welcome Image may be NSFW.
Clik here to view.

Thanks,

Maneesha
