jquery - How to check if a variable is a Timeout in Javascript? -

-

i decided contain code object separate out areas applied. advice here appreciated:

appconfig.loadelement , appconfig.cerrorelement these html elements:

<div id="loading" style="display:none;">loading...</div> <div id="cerror" style="display:none;">connection error.</div>   var loadingtimeoutinstance = null, cerrortimeoutinstance = null,     requestobj = {     reset: function() {         $(appconfig.loadelement).hide();         $(appconfig.cerrorelement).hide();         cleartimeout(loadingtimeoutinstance);         cleartimeout(cerrortimeoutinstance);     },     initiate: function() {         loadingtimeoutinstance = settimeout(requestobj.timeout, appconfig.loadingdelayms);     },     timeout: function () {         cleartimeout(loadingtimeoutinstance);         $(appconfig.loadelement).show();         cerrortimeoutinstance = settimeout(requestobj.cerror, appconfig.cerrordelayms);     },     cerror: function () {         cleartimeout(cerrortimeoutinstance);         $(appconfig.loadelement).hide();         $(appconfig.cerrorelement).show();     } }

an implementation so:

when asynchronous request made:

requestobj.reset(); requestobj.initiate();

after response returned:

requestobj.reset();

the problems have identified in requestobj.reset(): - why hide elements if hidden? - can't clear timeout vars (loadingtimeoutinstance , cerrortimeoutinstance) if not set timeouts yet - causes not work.

you don't need check if it's of type... is.

if(cerrortimeoutinstance) cleartimeout(cerrortimeoutinstance);

on website user have 1 group. , user can change group. it's made user.groups.clear() and user.groups.add(new_group) but it's not efficient, because there 2 sql query: delete, insert. how can change group update query? user , group related each other using manytomanyfield . means intersection table exists relating both entities, , if don't specify model map (using through attribute) django creates 1 you. looking @ sources django.contrib.auth.models see that's case. fortunatly, can access intermediary model using through attribute of manager (in case, user.groups.through ). can use regular model. example: >>> alice = user.objects.create_user('alice', 'alice@example.com', 'alicepw') >>> employee = group.objects.create(name='employee') >>> manager = group.objects.create(name='manager') >>> alice.groups.add(employee) >>> alice.groups.all() [<group: employee...
