This feature is well established and works across many devices and browser versions. It’s been available across browsers since November 2017.
The type read-only property of the Selection interface returns a string describing the type of the current selection.
A string describing the type of the current selection. Possible values are:
NoneNo selection has currently been made.
CaretThe selection is collapsed (i.e., the caret is placed on some text, but no range has been selected).
RangeA range has been selected.
In this example, the event handler will fire each time a new selection is made. console.log(selection.type) will return Caret or Range depending on whether the caret is placed at a single point in the text, or a range has been selected.
let selection;
document.onselectionchange = () => {
console.log("New selection made");
selection = document.getSelection();
console.log(selection.type);
};
