What's the proper way to get the position of an element on the page relative to the viewport (rather than the document).
offsety/x seemed promising:
http://docs.jquery.com/CSS/offset
But that's relative to the document. Is there an equivalent method that returns offsets relative to the viewport?

Here are two functions to get the page height and the scroll amounts (x,y) without the use of the (bloated) dimensions plugin:
ReplyDelete// getPageScroll() by quirksmode.com
function getPageScroll() {
var xScroll, yScroll;
if (self.pageYOffset) {
yScroll = self.pageYOffset;
xScroll = self.pageXOffset;
} else if (document.documentElement && document.documentElement.scrollTop) {
yScroll = document.documentElement.scrollTop;
xScroll = document.documentElement.scrollLeft;
} else if (document.body) {// all other Explorers
yScroll = document.body.scrollTop;
xScroll = document.body.scrollLeft;
}
return new Array(xScroll,yScroll)
}
// Adapted from getPageSize() by quirksmode.com
function getPageHeight() {
var windowHeight
if (self.innerHeight) { // all except Explorer
windowHeight = self.innerHeight;
} else if (document.documentElement && document.documentElement.clientHeight) {
windowHeight = document.documentElement.clientHeight;
} else if (document.body) { // other Explorers
windowHeight = document.body.clientHeight;
}
return windowHeight
}
