How to control Backspace Button/Browser Back in Fiori APP

[Former Member]

Hi All.,

               I want to control Backspace/Browser Back Button functionality in My custom Fiori app.

The issue is.,  If I Clicked outside Input control  and I pressed Backspace, by default it is taking browser back button functionality. 

Because of this, user is getting navigated from the current page to last visited page and user losing all other data which entered in rest of the fields.

Is there any possibilities of avoid this issue?

Found the solution for controlling Backspace key issue. Here is the code for same.

        window.addEventListener("keydown", function(e){

            if(e.keyCode == 8 && document.activeElement.value == undefined)

             {

                 e.preventDefault();

             }

         });

Note: Add it inside init()
