$.each($('#jie span'),function(){
var classname = $(this).attr('class');
if(classname !=null){
console.log(classname)
}
});或者console.log($("#jie span[class]"))

var tempList = [];
$('#jie span').each(function (){
if($(this).attr('class')){
tempList.push($(this))
}
});
console.log(tempList);或者console.log($("#jie span[class]"))
