Answer 2

I suppose you have to do few thing before delcare any django variable in temple by using javascript:

step 1: views.py

def XYZfunc(request, abc):
 try:
 some code here...
 content = {'abc': abc}
 return render(request, 'ProjectName/xyz_html_page.html', content)
 except(ObjectDoesNotExist, KeyError, ValueError):
 content = {'abc': abc}
 return render(request, 'ProjectName/xyz_html_page.html', content)

step 2: urls.py (optional)

url(r'^ProjectName/xyz_htmlpage_name/(?P<abc>[A-Z]+)/$', views.XYZfunc, name="abc"), 

(please note: if you are sending value through html url from views.py then use urls.py and if value is string then (?P[A-Z]+) )

Step 3: xyz_html_page.html

<script type="text/javascript">
var u = "{{abc}}";
</script>

i hope it might help you.
