In my current project, I am working on an Angular application that incorporates the Ace editor with ui-ace for text editing on the screen. I am looking to create a function that will execute when the cursor changes, updating a specific model object when the cursor is in a certain position. Additionally, I would like to have the ability to click a button that moves the cursor to a particular location and updates the model object accordingly. You can see a demonstration of this concept on this jsfiddle: http://jsfiddle.net/fpzknzej/3/
The model object updates if the cursor is positioned at the end of the word "print" on the second line. The issue arises when pressing the "Move Cursor!" button, as the $scope.$apply() call on line 30 throws an error while in progress. Omitting this line prevents the view connected to the model object from updating when using arrow keys to move the cursor.
After some consideration, it seems that my current approach may not be the most effective way to achieve this functionality. It appears that wrapping the changeCursor event to exclusively operate within the Angular environment might be a better solution. However, I am uncertain about the best method to tackle this task (I've come across mentions of custom directives) and whether there are any helpful resources available for understanding how to interact with third-party event handlers in Angular. Any guidance or suggestions in the right direction would be greatly appreciated.
