Django BigIntegerField value in JavaScript

I tried to retrieve data using id (BigIntegerField) in Django, but returned empty queryset.  

After trying several times, found all of the ids became 6977919360329322000, this id was not in database.

No idea why JavaScript changed this. is this the max number of JavaScript?  Converted parameter value from integer to string in frondend, done.
