Window: moveBy() method

Parameters

  • deltaX is the amount of pixels to move the window horizontally. Positive values are to the right, while negative values are to the left.
  • deltaY is the amount of pixels to move the window vertically. Positive values are down, while negative values are up.

Return value

None (undefined).

Examples

This example moves the window 10 pixels to the right and 10 pixels up.

js

function budge() {
  moveBy(10, -10);
}
