Window.mozInnerScreenY - Web APIs 编辑

Summary

Gets the Y coordinate of the top-left corner of the window's viewport, in screen coordinates.

Note: This coordinate is reported in CSS pixels, not in hardware pixels. That means it can be affected by the zoom level; to compute the actual number of physical screen pixels, you should use the nsIDOMWindowUtils.screenPixelsPerCSSPixel property.

Syntax
