[Django]-Django template filter – one line

Reading your use case, it doesn’t appear that you just want to remove lines. What if one of your form labels contains a ‘ character? Oops, your javascript is now invalid.
Django comes with a filter called escapejs which us used for precisely this problem.

With escapejs, you would type:

var newDivText = '{{ form.as_p|escapejs }}'

and you won’t have to worry about any characters destroying your javascript.
