javascript - Using KineticJS to remove drawn objects -

-

hopefully simple question here:

say i've used kineticjs draw line follows:

var redline = new kinetic.line({       points: [73, 70, 340, 23, 450, 60, 500, 20],       stroke: "red",       strokewidth: 15,       linecap: "round",       linejoin: "round"     });

and it's been added layer has been added stage.

but need remove line if never there react user event. how go doing this?

let's have layer below:

var layer = new kinetic.layer(....);

to remove redline layer write:

layer.remove(redline);
