 js代码


function showli(pid){
  var arrnav = ["1", "525", "531","541","60","14"];
  if(pid=='1'){ // 如果是1就显示全部的li标签
    $("ul.navigation li").show();
    return false;
  }

  // 否则就显示对应的class="s1"+pid的li标签


  $.each(arrnav, function(i, item){
    if(item==pid){
      $("ul.navigation li.sl"+pid).show();
    }else{
      $("ul.navigation li.sl"+item).hide();
    }
　　});
}
