I implemented javascript and one button when I click the button I want to pass UR as parameter to that function

What I have tried:

function <pre><pre lang="text"><script type="text/javascript">
        function LoadHGGames(param) {
            var url = param;
            window.open(url, 'winPop', '_blank,height=650,width=1000,left=0,top=0,resizable=yes,location=yes,status=no');
            window.focus();
            return false;
        }
    </script>

<asp:Button runat="server" Text="submit" OnClientClick="javascipt:LoadHGGames(https://v3livehguat.hointeractive.com/visitor/login/V3login.jsp?detectflash=false&lang=en&refreshfly=true)" />
