 多個A標籤，選中，未選中的顯示問題

第一步: Jsp 

 

<c:choose><c:when test="${cityId==21 }"><a href="javascript:;"  id="area0">所有</a><a href="javascript:;"   id="area20">靜安</a><a href="javascript:;"    id="area21">盧灣</a><a href="javascript:;"    id="area22">黃浦</a><a href="javascript:;"  id="area23">徐匯</a><a href="javascript:;"  id="area24">長寧</a><a href="javascript:;"  id="area25" >浦東</a><a href="javascript:;"   id="area26">虹口</a><a href="javascript:;"   id="area27">楊浦</a><a href="javascript:;"   id="area28" >普陀</a><a href="javascript:;"  id="area29">閔行</a><a href="javascript:;"  id="area30">閘北</a><a href="javascript:;"  id="area31">寶山</a><a href="javascript:;"  id="area32">嘉定</a><a href="javascript:;"  id="area33">松江</a><a href="javascript:;"  id="area34">南匯</a><a href="javascript:;"  id="area35">奉賢</a><a href="javascript:;"  id="area36">金山</a><a href="javascript:;"  id="area37">青浦</a><a href="javascript:;"  id="area38">崇明</a></c:when>

     <c:otherwise><a href="javascript:;"    id="area0">所有</a><a href="javascript:;"  id="area1">海淀</a><a href="javascript:;"    id="area2">朝陽</a><a href="javascript:;"  id="area3">東城</a><a href="javascript:;"  id="area4">西城</a><a href="javascript:;"  id="area5">崇文</a><a href="javascript:;"  id="area6">宣武</a><a href="javascript:;"  id="area7">豐臺</a><a href="javascript:;"    id="area9">房山</a><a href="javascript:;"   id="area10">門頭溝</a><a href="javascript:;"   id="area11">通州</a><a href="javascript:;"   id="area12">順義</a><a href="javascript:;"   id="area13">昌平</a><a href="javascript:;"   id="area14">密雲</a><a href="javascript:;"   id="area15">懷柔</a><a href="javascript:;"   id="area16">延慶</a><a href="javascript:;"   id="area17">平谷</a><a href="javascript:;"   id="area18">大興</a></c:otherwise></c:choose>

第二步：js 

 

function changeArea (areaId) {

changeAreaClassName(areaId);

｝

 

function changeAreaClassName(id){

  document.getElementById("area"+id).className=" current ";

      for(var i=0;i<100;i++){

      if(i != id && document.getElementById("area"+i)!=null){

      document.getElementById("area"+i).className=" otherCur ";

      }

      }

   }

 

 

 第三步 ： css

<style>

a.otherCur {

    color: #FFFFFF;

}

.tj_tit a.current {

     color :  #444444 ;

}

</style>
