Guide to adding content at a particular location using the ACE Editor from within an Angular Controller

I am currently developing a real-time collaborative editor using the Ace editor library, but I am facing challenges with inserting text at a specific position within the editor.

Specifically, I am looking to insert text at the cursor position when the user clicks a button.

Below is the code snippet I am working with:

<div ui-ace="aceOptions" ng-model="content"></div>

In my Angular controller, I have the following code:

 $scope.aceOptions = {
   mode : 'Javascript',
   theme : 'dreamweaver'
 };

 //content of ace editor
 $scope.content = "test";

 //handling button click to add text
 $scope.addTextOnClick = function(){
   //I need to retrieve the current cursor position and insert text here
   //This text should be added to the existing content
 }

I would greatly appreciate any assistance in resolving this issue.

Answer №1

To retrieve the current cursor position in your text editor, use the Edit.getCurrentPosition method.

After obtaining the cursor position, you can then determine the exact location in the text and insert content accordingly.

For more information, I recommend exploring the Ace documentation.

If you need to access the Editor instance, refer to this link: https://github.com/angular-ui/ui-ace#ace-instance-direct-access.

The $scope.aceLoaded function will receive the Ace Editor instance as its first argument

Take a look at the example provided below this section.
