点击span实现样式变化！求大神帮忙

Question

1.点击span 使span的class属性发生变化
class="btn btn-large btn-primary"------ btn-primary这是引入样式

2.原代码

    <div id="myTab" class="pull-right">        <a href="#listView" data-toggle="tab">
            <span class="btn btn-large" ><i class="icon-list"></i></span></a> 
        <a href="#blockView" data-toggle="tab">            
        <span class="btn btn-large btn-primary"><i class="icon-th-large"> </i></span></a>
    </div>

3.目前写成这样就是不生效

    <jsp:include page="/static/common/cart_js.jsp"/>
    <script type="text/javascript">
    
         $("span").each(function(i){            if(i==0){
                $("#listView span").on("click",function(){
    
                    $(this).addClass("btn btn-large");
                    })
            }else{
                $("#blockView span").on("click",function(){
    
                    $(this).addClass("btn btn-large btn-primary");
                    })
            }
        }); 
    </script>
