JS操作增加Class属性和移除删除Class属性

直接上代码

function go(a){
        if(a == 'shifu'){
            //移除属性
            var shop = document.getElementsByClassName("shop")[0];
            shop.classList.remove("ns-border-color");
            
            //增加属性
            var shifu = document.getElementsByClassName("shifu")[0];
            shifu.classList.add('ns-border-color');
             
            //赋值
            $("#thtype").val(a);  
          
        }
        if(a == 'shop'){
      
            var shifu = document.getElementsByClassName("shifu")[0];
            shifu.classList.remove("ns-border-color");
            
            var shop = document.getElementsByClassName("shop")[0];
            shop.classList.add('ns-border-color');
            
            $("#thtype").val(a); 
            
        }

        console.log(a)
    }
