Javascript函数下拉列表适用于多个下拉列表

Question

我有两个div正在尝试进行下拉，一个名为accountAcc，另一个名为forumAcc但是每当我点击accountAcc div或forumAcc时它只显示accountAcc，我如何区分这两个或完成此任务？ / p>

  <script type="text/javascript">
 function w3_open() {
document.getElementById("main").style.marginLeft = "12%";
document.getElementById("mySidenav").style.width = "12%";
document.getElementById("mySidenav").style.display = "block";
document.getElementById("openNav").style.display = 'none';
}
function w3_close() {
document.getElementById("main").style.marginLeft = "0%";
document.getElementById("mySidenav").style.display = "none";
document.getElementById("openNav").style.display = "inline-block";
}
function myAccFunc() {
  var x = document.getElementById("accountAcc", "forumAcc");
  if (x.className.indexOf("w3-show") == -1) {
    x.className += " w3-show";
    x.previousElementSibling.className += "w3-green";
} else {
    x.className = x.className.replace("w3-show", "");
    x.previousElementSibling.className =
    x.previousElementSibling.className.replace(" w3-green", "");
}
}
</script>
