Tips for removing residue from old watches

Our angularJS web components are integrated with a jqxGrid. Whenever a user makes edits in a cell, we implement a custom typeahead editor using Angular. However, I have noticed that after the editor is destroyed, my $watches array does not revert back to its original value.

To address this issue, I am creating a new isolateScope for my directive, which is then compiled and appended to the DOM element provided by JQX when the editor is required:

var scope = $rootScope.$new(true);
 var customEditor = $compile(directive)(scope);

I am seeking guidance on how to properly clean up these $watches. What steps should I take?

Answer №1

It seems that the issue lies in the creation of a new scope using

var scope = $rootScope.$new(true);

After the jqxGrid is done with the editor, this new scope may not be properly destroyed.

To address this, make sure to call

scope.$destroy();

Identifying when to execute this destroy call can be challenging. I suggest monitoring events like beforeEdit and afterEdit raised by jqxGrid; place the $destroy() call within an event handler for the afterEdit event.

Answer №2

Discover the best method for efficiently managing watchers. Is it necessary to remove angular $watch when scope is destroyed? I trust this information will be beneficial.
