Tooltip: destroyRecursive() leaves DOM

[Avachan]

Hi,

I have a big problem with some Memoryleaks in my page. I use Tooltips on Buttons and when I destroy the buttons the tooltips would not be destroyed.

At end of program lifetime I destroy all Tooltips with the following code :

        this.ttip[i].close();
        this.ttip[i].destroyRendering();
        this.ttip[i].destroyRecursive();
        this.ttip[i].domNode = null;

But the domNode is still there and I can't do anything against it. My Memoryleak programm ( Drip 0.5 ) show me the Tooltip with one reference on it. But I don't know where this is come from.

Sincerly, Ava-chan

Hi Ava,

I think this is just your misunderstanding. All Tooltip widgets utilize the same (single) MasterTooltip widget to actually display a tooltip. (Flyweight pattern.)

On IE, that single MasterTooltip widget is destroyed on page unload, along with all the other widgets on the page. Calling destroyRecurisve() on individual tooltips will destroy the Tooltip widgets themselves (which are typically plain <span> nodes), but leave that MasterTooltip.

To demonstrate, in our test_Tooltip.html file I can execute

dijit.byId("t_tooltip").destroyRecursive()

in the firebug console and then looking at the HTML tab the t_tooltip <span> has disappeared.

If you can supply a testcase where that isn't happening then please attach it (with the attach file button) and reopen this ticket.

PS: I recommend ​IEJSLeaksDetector over Drip, it seems to work much better.
