javascript - append function not working to textarea after text edited -

append function not appending when textarea text edit . tried pull in current value, append, , set back. not working .

function getserial() { var getvalue = $(serial).val() + ",\n"; var showvalue = "#showserial"; $(showvalue).append(getvalue); }

if utilize val() replace before submitted value . value of text-area added comma al-2, al-3 every single submit .

try using val() instead of append(): i've created test fiddle, work you?

function getserial (){ var showvalue = $("#showserial"); var getvalue = $(serial).val()+ ",\n"; if(showvalue.val()){ $(showvalue).val(showvalue.val() + getvalue); }else { $(showvalue).val(getvalue); } }

python - How to add an model instance to a django queryset? - it seems django queryset behaves somehow python list. but doesn't back upwards list's .append() method know. what want like: from my_django_app.models import mymodel queryset = mymodel.objects.none() queryset.append(mymodel.objects.first()) ## no list's .append() method! is there way add together model instance existing queryset? no. queryset representation of query - hence name - not arbitrary collection of instances. if need actual queryset rather list, seek accumulating ids of objects need , getting objects via __in query: list_of_ids = [] list_of_ids.append(my_id) ... queryset = mymodel.objects.filter(id__in=list_of_ids) this isn't efficient, though. python django
