JS代码在火孤里没有反应

[从此不换网名]

以下的这段代码，在IE可以自动显示/隐藏，可以火孤就没有反应，请各位路过走过的朋友，帮忙看一下，是那里错了，谢谢各位

    <script type="text/javascript">
		function hebj(he){
			switch (he){
				case hebj01:
				document.getElementById("hebj01").className="hebj";
				document.getElementById("hebj02").className="hewb";
				document.getElementById("hebj03").className="hewb";
				document.getElementById("hebj04").className="hewb";
				document.getElementById("hebj05").className="hewb";
				break;
				case hebj02:
				document.getElementById("hebj01").className="hewb";
				document.getElementById("hebj02").className="hebj";
				document.getElementById("hebj03").className="hewb";
				document.getElementById("hebj04").className="hewb";
				document.getElementById("hebj05").className="hewb";
				break;
				case hebj03:
				document.getElementById("hebj01").className="hewb";
				document.getElementById("hebj02").className="hewb";
				document.getElementById("hebj03").className="hebj";
				document.getElementById("hebj04").className="hewb";
				document.getElementById("hebj05").className="hewb";
				break;
				case hebj04:
				document.getElementById("hebj01").className="hewb";
				document.getElementById("hebj02").className="hewb";
				document.getElementById("hebj03").className="hewb";
				document.getElementById("hebj04").className="hebj";
				document.getElementById("hebj05").className="hewb";
				break;
				case hebj05:
				document.getElementById("hebj01").className="hewb";
				document.getElementById("hebj02").className="hewb";
				document.getElementById("hebj03").className="hewb";
				document.getElementById("hebj04").className="hewb";
				document.getElementById("hebj05").className="hebj";
				break;
			}
			alert(he);

return hebj(hebj01)
也写
return hebj(‘hebj01’)

按照：knightzhuwei 的方法，解决了FF里的问题，谢谢各位的热心回复！

如果 knightzhuwei ，可以带上点说明，为什么要这样做，FF才能生效呢

[knightzhuwei]

hebj('hebj02'); 参数是字符串
case "hebj02": 判断字符串 这个比较保险

hebj(hebj02); 参数是dom对象
case hebj02: 判断dom对象 ff可能不支持
