jqxDateTimeInput and jqxCalendar memory leak

[maufarinelliParticipant]

Hi,

We are using jqxDateTimeInput in our application. But we’ve just realised that it is causing a memory leak.
We are using inside a modal component, and when it is destroyed, the jqxDateTimeInput is detroyed just after and rowser keep a Detached DOM tree of it in memory.

Ok, we fixed that explicitely calling self.settings.jqxDateTimeInput(‘destroy’);, but we still have some Detached DOM tree of its jqxCalendar that is instantiated by jqxDateTimeInput.

Do we have a way to have access to the jqxCalendar instance created internally by jqxDateTimeInput?
if yes, we could destroy it by ourselves. However, I think you guys could improve it forcing to destroy the scope of its calendar instance once it is destroyed too.

Thanks

Hi maufarinelli,

It is not a memory leak, because you have to call “destroy” method to destroy the component. The “destroy” method of jqxDateTimeInput destroys the calendar as well.

I would say it is, indeed, a bug.
The Angular jqxSliderComponent doesn’t implement OnDestroy interface.

It should, and should call the ‘destroy’ method of the underlying widget by itself.
It is his responsibility to do so.

AFAICT, every Angular component provided that wraps a widget whould implement an OnDestroy method.

Hi,

We are using jqxWidget components for a long time and now we realized that jqxDateTimeInput and JqxCalender both has memory leaks. It is accumulating approx 620kb memory every in our application. so we tried to destroy both manually but that does not work as well. it still have the large number of detached nodes and even memory size grows.

Here is the running sample of the memory leak use case https://jsfiddle.net/skhajan/24eamneg/.

Thanks

When “destroy” is called, memory occupied by jqxDateTimeInput and Calendar is released when the GC is called.
