i want to display popup message like (welcome <user>) when user will log in.  

i can add this message to a section of the page by using Django messages   

 **Like** `messages.success(request,welcome {request.user}')`  

 and **in template**   
`{% if messages %}`   
`<ul class="messages">`   
`{% for message in messages %}`   
`<li class="{{ message.tags }}">{{ message }}</li>`  

`{% endfor %}`

`</ul>`

`{% endif %}`   

but i don't want that.
i just want a popup message for few seconds   

How can i do that in a Django project?  
 Or, is there any way of doing that by using java script event listener?   
 Thanks is advance
