Page body part: Window.screentop

HTML Precise positioning: Scrollleft,scrollwidth,clientwidth,offsetwidth
ScrollHeight: Gets the scroll height of the object.
ScrollLeft: Sets or gets the distance between the left edge of the object and the leftmost of the currently visible content in the window
ScrollTop: Sets or gets the distance between the top of the object and the top of the visible content in the window
ScrollWidth: Gets the scrolling width of the object
Offsetheight: Gets the height of the object relative to the layout or parent coordinates specified by the parent coordinate OffsetParent property
Offsetleft: Gets the calculated left position of the object relative to the layout or the parent coordinate specified by the OffsetParent property
OffsetTop: Gets the computed top position of the object relative to the layout or the parent coordinate specified by the OffsetTop property
Event.clientx horizontal coordinates of relative documents
Event.clienty vertical coordinates of relative documents
Event.offsetx horizontal coordinates relative to the container
Event.offsety the vertical coordinate of the relative container
Document.documentElement.scrollTop The vertical scrolling value
Event.clientx+document.documentelement.scrolltop horizontal coordinates of relative documents + amount of vertical scrolling
Ps:document.documentelement.scrolltop+document.body.scrolltop (compatible with IE, FF, Chrome)
Ie,firefox differences are as follows:
IE6.0, ff1.06+:
clientwidth = width + padding
clientheight = height + padding
offsetwidth = width + padding + border
offsetheight = height + padding + border
ie5.0/5.5:
ClientWidth = Width-border
ClientHeight = Height-border
offsetwidth = width
offsetheight = height
(Need to mention: the Margin property in CSS, and clientwidth, Offsetwidth, clientheight, offsetheight are irrelevant) EX1: Css: #bgScreen, #bgIFrame {position:fixed; top:0; left:0; z-index:999; width:100%; background: #000; Filter:alpha (opacit Y=20); opacity:0.2; _position:absolute; _top:expression (Documentelement.scrolltop+documentelement.clientheight-this.offsetheight); } #bgIFrame {z-index:998; Filter:alpha (opacity=0); opacity:0;} Js:$ ("#bgScreen, #bgIFrame"). CSS ("height", jQuery.browser.version = = ' 6.0 '? window.screen.height-160: ' 100% ');EX2: Js: var finddimensions = function () { var winwidth = 0; var winheight = 0; Get window width if (window.innerwidth) { Winwidth = window.innerwidth; } else if ((document.body) && (document.body.clientWidth)) { Winwidth = Document.body.clientWidth; } Get window Height if (window.innerheight) { Winheight = Window.innerheight; } else if ((document.body) && (document.body.clientHeight)) { Winheight = Document.body.clientHeight; } Get the window size by examining the body inside the document if (document.documentelement && document.documentElement.clientHeight && Document.documentElement.clientWidth) { Winheight = Document.documentElement.clientHeight; Winwidth = Document.documentElement.clientWidth; } return winwidth + "-" + winheight; } var _height = Finddimensions (). Split ("-");
