Window.moveBy()

在此页

moveBy() 方法在 Window interface moves the current window by a specified amount.

注意： This function moves the window relative to its current location. In contrast, window.moveTo() moves the window to an absolute location.

window.moveBy(deltaX, deltaY)

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.

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

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