Set Value for ace editor without selecting the whole editor

Question

So you can set value of an ace editor with setValue but after setting the value, the editor will select the whole value of the editor. How do you disable this? This mean when I set value of ace editor to Hello world, it won't highlight Hello world

Answer 1

You can use the second parameter to control cursor position after setValue

editor.setValue(str, -1) // moves cursor to the start
editor.setValue(str, 1) // moves cursor to the end

Answer 2

You can even use clearSelection() after you do an setValue();

editor.setValue("Hello World");
editor.clearSelection(); // This will remove the highlight over the text

Answer 3

I'm not sure if editor.setValue() is a remnant from the old days or what, but the proper way to set an editor's content is

editor.session.setValue(text);

or

editor.getSession().setValue(text);

This will NOT select the text, so there's no need to do any of the things mentioned on this page.

editor.setValue() explicitly selects all (and forgets to unselect it); but there's no reason to use it.

Answer 4

This works for me!

editor.setValue(editor.getValue(), 1);

Answer 5

I've been having your same issue.

Even though you can set the second parameter to either 1 or -1, I think you should also check this: https://ace.c9.io/api/editor.html#Editor.setValue

Editor.setWrapBehavioursEnabled(Boolean enabled)

Use this right after creating the editor.

This works very well for me. The difference between this method and the one shared by a user is that the caret's position is not changed, you can move it yourself using Editor.selection.moveTo(row, column), this way the user won't experience weird caret position changes when using, say, CTRL+Z to undo an action :)

Answer 6

 var prevtext = $("#editor").val();
 prevtext = prevtext + "<br/>";
 $("#editor").val(prevtext).blur();
