var computerselection = "";
var y = (Math.floor(Math.random() * 10) + 1);

if (y >= 1 && y <= 4) {
    computerselection = "Rock";
}
else if (y >= 5 && y <= 7) {

Used Bootstrap Alert and Prompt.

 

Simple if conditions to check who has won.

 

Here x is the User Selection from Prompt.

if (x == values[computerselection])
        bootbox.alert("Game Draw--Better Luck Next Time");

    ---------------------------------------------------------------------------------------
    else if (values[computerselection] == 1 && x == 2)
        bootbox.alert("Computer have won  Computer Selected " + computerselection);

    --------------------------------------------------------------------------------------------

   else if ((values[computerselection] == 1 && x == 3) || (values[computerselection] == 2 && x == 1) || (values[computerselection] == 3 && x == 2))
       bootbox.alert("Computer have won  Computer Selected " + computerselection);

   ----------------------------------------------------------------------------------------------

    else if ((values[computerselection] == 1 && x == 2) || (values[computerselection] == 2 && x == 3) || (values[computerselection] == 3 && x == 1))
        bootbox.alert("You won against computer -- Computer Selected  " + computerselection);
