Passing data from one view to another

Hi

I have created two JS views(Log in and Registration).I want to pass username enterd in login view and display it a text box in registration page.The navigation is happening and I used sap.m.URLhelper.redirect but the value is not getting passed.I used sap.ui.getCore().getElementById("idLogIn1") .byId("input2").getValue() wherein idLogIn1 is the id for loginview and input2 is the id for textbox(from where value need to be obtained)..Looking forward to your reply.

Thanks

Muthu
