For more information, see ScreenY Offset between the mouse and the upper left corner of the screen PageY The offset between the mouse and the upper left corner of the page (its value is not affected by the scroll bar) This attribute is not supported under IE9 However, you can write some code to calculate it.

property.2. In the case where the element has an upper border border-top, the layery is one more border-top than the value of offsety.1 var offsetY = event.offsety| | (Event.layery +element.bordertopwidth); 2 // Note that the element.bordertopwidth here need to be replaced with the width of the top border of the calculated element. The Layery and OffsetY properties make it easy to calculate the offset of the mouse relative to the bound mouse event element, which is useful at some point.Here in

What are the differences between clientx, clienty, offsetx, offsety, screenx, screeny, X, and Y? Clientx, clienty is the current position of the mouse relative to the webpage. When the mouse is in the upper left corner of the page, clientx = 0 and clienty = 0; Offsetx and offsety are the positions of the current mouse relative to a certain area in the webpage. When the mouse is located in the upper left corner of the area in the page, offsetx = 0 an

ClientX: When a mouse event occurs (either onclick, omousemove,onmouseover, etc.), the mouse is positioned relative to the x-axis of the browser (which is said to be the active area of the browser); ClientY: When a mouse event occurs, the mouse is positioned relative to the y-axis of the browser (which is what it says is the active area of the browser); ScreenX: The position of the mouse relative to the x-axis of the display screen when the mouse event occurs;

ClientX, clientY is the current position of the mouse relative to the webpage. When the mouse is in the upper left corner of the page, clientX = 0 and clientY = 0; OffsetX and offsetY are the positions of the current mouse relative to a certain area in the webpage. When the mouse is located in the upper left corner of the area in the page, offsetX = 0 and offsetY = 0; ScreenX and screenY are relative to the user's display. X and y are the locations of

area on the System screen, including any system elements, such as the taskbar. Because features such as height, width, innerheight, and innerwidth cannot accurately describe the window boundary, the approximate pixel value must be subtracted. To make full use of the fullscreen feature of the browser, simply add the following script program: VaR STR = "Left = 0, screenx = 0, Top = 0, screeny = 0, fullscreen "; We do not need to check whether the brows

The difference between Clientx/clienty and Screenx/screeny There are times in JavaScript where we need to get the mouse hover position to do some special processing. The MouseEvent object needs to be used. The MouseEvent object provides two sets of properties for locating the position of the mouse: Clientx/clienty and Screenx/screeny. In addition to these two sets of properties we often use Pagex/p

. The purpose of introducing the Self object is only to correspond to the top and parent objects, so it does not contain extra values.All of these objects are properties of the Window object and can be accessed in the form of Window.parent, Window.top, and so on. At the same time, this also means that different levels of window objects can be concatenating up, such as window.parent.parent.frames[0].Window positionThere are many properties and methods used to determine and modify the location of

Welcome to the CSDN-markdown Editor, csdn-markdownDifference between clientX/clientY and screenX/screenY In JavaScript, we sometimes need to get the cursor position for some special processing. In this case, the MouseEvent object is used. The MouseEvent object provides two sets of attributes to locate the mouse position: clientX/clientY and screenX/screenY. In addition to these two sets of attributes, we
