 火狐 IE兼容：

function chooseGeme(){
  var games =document.getElementsByName("games")[0];
  var gameoid = games.options[games.selectedIndex].value;
  if(gameoid!=""){
   window.location.href='userExternal.do?method=choseUserForward&type=1&gameoid='+gameoid;
  }else{
    alert("请选择正确的大赛");
  }
  }

不兼容：

  function chooseGeme(){
  var gameoid =  document.getElementById("games").value;
  if(gameoid!=""){
   window.location.href='userExternal.do?method=choseUserForward&type=1&gameoid='+gameoid;
  }else{
    alert("请选择正确的大赛");
  }
  }
