OnClick HTML button : call Javascript function + location.href (Django)

Question

How can I put 2 operations in my onclick parameter, one calling a Javascript function, the other giving location.href with Django tags ? I want to make something appear on the page before redirecting to another page.

I want to do something like this :

onclick="chargement();location.href='{% url 'resumefic' upload.0.pk %}';"

but my function chargement() isn't called, only the redirection works.

I can't put the location.href in a JS function as I'm using Django tags... Can someone help ?

Answer 1

The problem is that the redirection occurs before you can see what the chargement function has done. Try adding a delay before the redirection, for example replace your code with.

onclick="chargement();setTimeout(function(){location.href='{% url 'resumefic' upload.0.pk %}';},1000);"
