2.PageX and Clientx Pagex refers to the position of the mouse on the page, to the left of the page is the reference point Clientx refers to the distance from the left side of the visible area, the scroll bar to scroll to the position of the reference point. Each browser is the same. That is, when there is a scrollbar, clientx is less than PageX

ie678 does not recognize Pagex pagey=clienty+scrolltop-clienttop, (only the y-axis, the x-axis, the same as the same) position on the page = viewable area position + page ScrollBar cut to height-self-border height, or directly relatively clear

3, ScreenX mouse in the screen position, refers to the mouse to the computer screen to the left of the distance. Each browser is the same. The difference from Clientx is that Clientx is the distance to the browser. For example: When the page is zoomed out and dragged to the middle of the screen, Screnx is greater than ClientX

4, OffsetX and Layerx in order to be compatible with the browser, Layerx is FF, chrome identification, OFFSETX is except FF.

If the trigger element is set to position, then offsetx equals Layerx If the page has scroll bars, add a scrolling distance.

LAYERX:FF is unique, relative to the parent element's position, the mouse relative to "the element of the triggering event is closest to that element in the hierarchical relationship, set the position parent element" the position of the boundary, starting from the upper left corner of border, that is, if the parent

element exists border, the coordinate origin is in the upper-left corner of the border, not the upper-left corner of the content area. Offsetx:ie unique, the mouse relative to the "trigger event element" position, from the upper left corner of the content area to start positioning, not from the upper left corner of the border! This property is useful for determining where the mouse point is in an element, FF

There are no directly substituted properties.
