说明：点击空白处下拉框消失

本文中的例子是点击id为cho的span，即<span id="cho">选择</span>时下拉框消失。但是还有另外一种情况，就是所要点击的id里包含了两个以上容器，如：<div id="shool" ><span>选择您所在的学校</span><b></b></div>
当点击id为shool的容器时，用以上代码并不能实现想要的效果，即：下拉框不能显示出来，所以要将以上代码稍作调整


document.onclick=function(e){ 
    var e=e?e:window.event; 
    var tar = e.srcElement||e.target; 
    if(tar.id!="shool" && $(tar).parent().attr("id")!="shool"){ 
      if($(tar).attr("class")=="div_d"){ 
        $(".mail_tit ul.div_d").css("display","block") 
      }else{ 
        $(".mail_tit ul.div_d").css("display","none"); 
      } 
    } 
  }
