This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
The GlobalEventHandlers.onselectstart property represents the event handler that is called when a selectstart event reaches this object, i.e. when the user starts to make a new text selection on a web page.
Syntax
obj.onselectstart = function;
Example
document.onselectstart = function() {
console.log("Selection started!");
};
For a full example, see our Key quote generator demo.
