I am working to build a browser extension. I am a complete beginner at creating extensions as well as json and js; at the moment I am working to create this extension in Opera.
Ultimately, the final application of this extension will be as follows:
- Grab ALL text in an editable text object via right-click context menu (specifically, NOT SELECTED/HIGHLIGHTED TEXT)
- Apply specific modifications to it as dictated by user selection in the context menu.
- Then replace the original text with the modified text within the editable text object.
Repeated for its importance: I would like to gain access to all of the text in an editable object, not simply the highlight/selected portion of it. In other words, I want to right click on an editable object, such as a textbox, and grab all of the text within it.
And this is where I’ve run into a problem: how do I grab all of the text in an editable object, not just the selection/highlighted portion of the text in the object?
For my basis, I am using this simple example: https://dev.opera.com/extensions/context-menus/
I’ve also found this 10 year old post ("Programmatically select text in a contenteditable HTML element?") but I do not have enough experience to try to implement it to see if the solutions work.
If anyone is familiar with how to achieve the basics of this, I would be grateful if you could provide me with a rough outline of code to show me how to properly implement the solution from the link above or another method that would work.
Thank you kindly.
