To create a dotted line border in KineticJS, you can use a combination of dashed stroke styles and line properties. Here's an example of how you can create a dotted line border for a rectangle in KineticJS:

var stage = new Kinetic.Stage({
  container: 'container',
  width: 500,
  height: 500
});

var layer = new Kinetic.Layer();

var rectangle = new Kinetic.Rect({
  x: 50,
  y: 50,
  width: 200,
  height: 100,
  stroke: 'black',
  strokeWidth: 1,
  dash: [10, 5] // set the dash array to create a dotted line
});

layer.add(rectangle);
stage.add(layer);

In this example, we create a rectangle shape and set the dash property to an array [10, 5], where the first number represents the length of the dash and the second number represents the length of the gap between dashes. This will create a dotted line border for the rectangle shape.

You can customize the dash array to create different types of dashed or dotted lines according to your requirements.
