This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.
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!");
};
