Mornign Guys/Girls
I am having some trouble nulling out or stopping some dynamic
variables i have created ...
I have built a dynamic window system which does alot of things, one is
checking a database to ensure the most up to date information is in
input boxes ... Now to check this i create a dynamic variable when the
contents is loaded via an ajax request...
[code]
checkRecord_<?php echo($rand); ?> = new PeriodicalExecuter(function()
{
testingRecord('<?php echo($rand); ?>');
},7);
[/code]
in this rand is just a unix epoch on when the page was created and is
referenced throughout the whole entire page and all its elements ...
for those that dont know php here is a simpler version of the code
[code]
checkRecord_123423414 = new PeriodicalExecuter(function() {
testingRecord('123423414');
},7);
[/code]
in the DOM there is now a variable called
"checkRecord_123423414" (please bear in mind this is dynamic so i cant
just do checkRecord_123423414=null; when i want to null it or stop the
object as the ending string is allways different dependant on what
page you are on ...
Now the problem i get is when closing the windows in the system (which
are just div containers) i have to stop observing alot of stuff ...
this is done quite easily with stopObserving();
But i need to stop the PeriodicalExecutor from continuing once the
window is closed ...
i have tried to use "checkRecord_+e.stop();" (`e` is the random string
passed to it) but it gives me a syntax error
i have tried to use "checkRecord_+e=null;" but the interpretor does
not recognise the dynamic variable ..... is there a way i can assign
the variable to something so it inherits all of the things i need to
stop in it ..
Something like (PSUEDO CODE)
[psuedo code]
var blah='checkRecord_'+e;
blah=null;
[/psuedo code]
Will this inherit the "new PeriodicalExecutor" stuff in it so i can
null the object and stop it listening ?
It allready half works just by closing the window, but if you close it
while its doing a request (testingRecord();)
it moans about things being null (as they are removed from the dom
prior to the object being nulled out !!!
Sorry if this makes no sense at all !! if anything needs clarifying
please ask
Regards
Alex
