Strange behavior with the novalidate attribute

[raph146]

Hello,
I have an issue with a form which template extends from https://github.com/moccu/django-cruditor/blob/master/cruditor/templates/cruditor/form.html.
The issue seems to originate in the "novalidate" attribute from the form tag in the template right there :
https://github.com/moccu/django-cruditor/blob/81b074dc1c943cee064e774ed0ae80a8291c5497/cruditor/templates/cruditor/form.html#L14
Basically, in my case, when I click my form's validation button, every numerical field in which there are non numerical characters or expressions are emptied before sending the POST request, instead of preventing the form validation and displaying errors.
Although I get the right behavior when I remove the "novalidate" attribute from the form tag.
Is this intended at all ? I was also wondering what purpose is the "novalidate" attribute serving in most cases.
I am relatively new to Django so I guess my question might seem trivial, I'm sorry if it is.

EDIT : To add a bit more context, I'm using Bootstrap with django-tapeforms

The novalidate tag disables the validation of field inputs in the browser. Now sure why the brower doesn't send the data to the server. Are you sure its not sent? Or is it simply not available in form.cleaned_data as it is not a valid value?

Actually it seems to be due to browser behavior. Nothing to do with cruditor with this. And the use of novalidate seems to be a good choice since browser-side validation is sometimes broken.
