html a 标签的格式调整

[apexMing]

hi， 大牛，深夜发帖求教。
css部分如下：

.gl_wrap ol li div a .sel{display:block;float:left;height:22px;line-height:22px;color:#666;padding:0 8px;background:#66a800}
.gl_wrap ol li div a .unsel{display:block;float:left;height:22px;line-height:22px;color:#666;padding:0 8px}

html部分如下：

		<div class="gl_wrap">	
			<h3><a >主题</a></h3>
			<ol>
					<li><div id="娱乐" onclick="selTab1(this, 'ztyl');"><a name='ztyl' class='unsel'>娱乐</a></div></li>
					<li><div id="生活" onclick="selTab1(this, 'ztsh');"><a name='ztsh' class='unsel'>生活</a></div></li>
					<li><div id="文化" onclick="selTab1(this, 'ztwh');"><a name='ztwh' class='unsel'>文化</a></div></li>
					<li><div id="艺术" onclick="selTab1(this, 'ztys');"><a name='ztys' class='unsel'>艺术</a></div></li>
					<li><div id="社交" onclick="selTab1(this, 'ztsj');"><a name='ztsj' class='unsel'>社交</a></div></li>
					<li><div id="行摄" onclick="selTab1(this, 'ztxs');"><a name='ztxs' class='unsel'>行摄</a></div></li>
					<li><div id="体育" onclick="selTab1(this, 'ztty');"><a name='ztty' class='unsel'>体育</a></div></li>
					<li><div id="求职" onclick="selTab1(this, 'ztqz');"><a name='ztqz' class='unsel'>求职</a></div></li>
					<li><div id="" onclick="selTab1(this, 'ztqb');"><a name='ztqb'  class="youth">全部</a></div></li>
			</ol>
		<!--     <span class="sp_toggle"><a href="javascript:void(0);" class="more_selector">更多</a></span>    <div class="clear"></div> -->
		</div>

js部分如下：

	activity_class=""
	cur_zt_obj=""
	function selTab1(obj, a_name){
		activity_class = obj.id
		var a_obj = document.getElementsByName(a_name)[0];
		alert(a_obj.class)
		alert(obj.class)
		if(cur_zt_obj != ""){
			cur_zt_obj.class=""
		}
		cur_zt_obj = a_obj;
		a_obj.class = 'sel';
		//alert('plugin.php?id=group_clc:group_clc&mod=youji&time='+activity_time+'&class='+activity_class+'&nature='+activity_nature+'&order='+activity_order+'&page=act_list','group_latest')
		ajaxget('plugin.php?id=group_clc:group_clc&mod=youji&time='+activity_time+'&class='+activity_class+'&nature='+activity_nature+'&order='+activity_order+'&page=act_list','group_latest')
	}
	
	activity_time ="";
	cur_sj_obj = "";
	function selTab2(obj, a_name){
		activity_time = obj.id
		var a_obj = document.getElementsByName(a_name)[0];
		alert(a_obj.class)
		alert(obj.class)
		if(cur_sj_obj != ""){
			cur_sj_obj.class=""
		}
		cur_sj_obj = a_obj;
		a_obj.class = 'sel';
		ajaxget('plugin.php?id=group_clc:group_clc&mod=youji&time='+activity_time+'&class='+activity_class+'&nature='+activity_nature+'&order='+activity_order+'&page=act_list','group_latest')
	}

	activity_nature=""
	cur_xz_obj = "";
	function selTab3(obj, a_name){
		activity_nature = obj.id
		var a_obj = document.getElementsByName(a_name)[0];
		alert(a_obj.class)
		alert(obj.class)
		if(cur_xz_obj != ""){
			cur_xz_obj.class=""
		}
		cur_xz_obj = a_obj;
		a_obj.class = 'sel';
		ajaxget('plugin.php?id=group_clc:group_clc&mod=youji&time='+activity_time+'&class='+activity_class+'&nature='+activity_nature+'&order='+activity_order+'&page=act_list','group_latest')
	}

	activity_order=""
	cur_px_obj = "";
	function selTab4(obj, a_name){
		activity_order = obj.id
		var a_obj = document.getElementsByName(a_name)[0];
		alert(a_obj.class)
		alert(obj.class)
		if(cur_px_obj != ""){
			cur_px_obj.class=""
		}
		cur_px_obj = a_obj;
		a_obj.class = 'sel';
		ajaxget('plugin.php?id=group_clc:group_clc&mod=youji&time='+activity_time+'&class='+activity_class+'&nature='+activity_nature+'&order='+activity_order+'&page=act_list','group_latest')
	}

现在运行效果点击标签如“艺术”，之后并不能改变其背景色。
想要的效果就是点击之后标记为选中。

你的js吓倒我了，如果是一万个a你是不是给我整出一万个function(){}？

而且selTab1中的alert部分都是undefine.

function selTab1(obj, a_name){
    activity_class = obj.id
    var a_obj = document.getElementsByName(a_name)[0];
    alert(a_obj.class)
    alert(obj.class)
    if(cur_zt_obj != ""){
        cur_zt_obj.class=""
    }
    cur_zt_obj = a_obj;
    a_obj.class = 'sel';
    //alert('plugin.php?id=group_clc:group_clc&mod=youji&time='+activity_time+'&class='+activity_class+'&nature='+activity_nature+'&order='+activity_order+'&page=act_list','group_latest')
    ajaxget('plugin.php?id=group_clc:group_clc&mod=youji&time='+activity_time+'&class='+activity_class+'&nature='+activity_nature+'&order='+activity_order+'&page=act_list','group_latest')
}

function selTab1(obj, a_name){
      activity_class = obj.id
      var a_obj = document.getElementsByName(a_name)[0];
      
      if(cur_zt_obj != ""){
        cur_zt_obj.className =""
      }

      cur_zt_obj = a_obj;
      a_obj.className = 'sel';
      //alert('plugin.php?id=group_clc:group_clc&mod=youji&time='+activity_time+'&class='+activity_class+'&nature='+activity_nature+'&order='+activity_order+'&page=act_list','group_latest')
      // ajaxget('plugin.php?id=group_clc:group_clc&mod=youji&time='+activity_time+'&class='+activity_class+'&nature='+activity_nature+'&order='+activity_order+'&page=act_list','group_latest')
