python+django+js实现搜索框有值显示搜索结果，无值隐藏搜索结果

前端：

    
    {% if msg %}
        
{{ msg }}
    {% else %}
        

            

                
IP address

                
PowerOn
                
PowerOff
            
            

                
{{ IP_name }}
                
PowerOn
                
Restart
            
        
    {% endif %}

 JS：

后端：
