Some small +positioning errors - usually with Window positioning - occur on the +Macintosh platform. + +FUNCTIONS: +getAnchorPosition(anchorname) + Returns an Object() having .x and .y properties of the pixel coordinates + of the upper-left corner of the anchor. Position is relative to the PAGE. + +getAnchorWindowPosition(anchorname) + Returns an Object() having .x and .y properties of the pixel coordinates + of the upper-left corner of the anchor, relative to the WHOLE SCREEN. + +NOTES: + +1) For popping up separate browser windows, use getAnchorWindowPosition. + Otherwise, use getAnchorPosition + +2) Your anchor tag MUST contain both NAME and ID attributes which are the + same. For example: + <A NAME="test" ID="test"> </A> + +3) There must be at least a space between <A> </A> for IE5.5 to see the + anchor tag correctly. Do not do <A></A> with no space. +*/ + +// getAnchorPosition(anchorname) +// This function returns an object having .x and .y properties which are the coordinates +// of the named anchor, relative to the page. +function getAnchorPosition(anchorname) { + // This function will return an Object with x and y properties + var useWindow=false; + var coordinates=new Object(); + var x=0,y=0; + // Browser capability sniffing + var use_gebi=false, use_css=false, use_layers=false; + if (document.getElementById) { use_gebi=true; } + else if (document.all) { use_css=true; } + else if (document.layers) { use_layers=true; } + // Logic to find position + if (use_gebi && document.all) { + x=AnchorPosition_getPageOffsetLeft(document.all[anchorname]); + y=AnchorPosition_getPageOffsetTop(document.all[anchorname]); + } + else if (use_gebi) { + var o=document.getElementById(anchorname); + x=AnchorPosition_getPageOffsetLeft(o); + y=AnchorPosition_getPageOffsetTop(o); + } + else if (use_css) { + x=AnchorPosition_getPageOffsetLeft(document.all[anchorname]); + y=AnchorPosition_getPageOffsetTop(document.all[anchorname]); + } + else if (use_layers) { + var found=0; + for (var i=0; i<document.anchors.length; i++) { + if (document.anchors[i].name==anchorname) { found=1; break; } + } + if (found==0) { + coordinates.x=0; coordinates.y=0; return coordinates; + } + x=document.anchors[i].x; + y=document.anchors[i].y; + } + else { + coordinates.x=0; coordinates.y=0; return coordinates; + } + coordinates.x=x; + coordinates.y=y; + return coordinates; + } + +// getAnchorWindowPosition(anchorname) +// This function returns an object having .x and .y properties which are the coordinates +// of the named anchor, relative to the window +function getAnchorWindowPosition(anchorname) { + var coordinates=getAnchorPosition(anchorname); + var x=0; + var y=0; + if (document.getElementById) { + if (isNaN(window.screenX)) { + x=coordinates.x-document.body.scrollLeft+window.screenLeft; + y=coordinates.y-document.body.scrollTop+window.screenTop; + } + else { + x=coordinates.x+window.screenX+(window.outerWidth-window.innerWidth)-window.pageXOffset; + y=coordinates.y+window.screenY+(window.outerHeight-24-window.innerHeight)-window.pageYOffset; + } + } + else if (document.all) { + x=coordinates.x-document.body.scrollLeft+window.screenLeft; + y=coordinates.y-document.body.scrollTop+window.screenTop; + } + else if (document.layers) { + x=coordinates.x+window.screenX+(window.outerWidth-window.innerWidth)-window.pageXOffset; + y=coordinates.y+window.screenY+(window.outerHeight-24-window.innerHeight)-window.pageYOffset; + } + coordinates.x=x; + coordinates.y=y; + return coordinates; + } + +// Functions for IE to get position of an object +function AnchorPosition_getPageOffsetLeft (el) { + var ol=el.offsetLeft; + while ((el=el.offsetParent) != null) { ol += el.offsetLeft; } + return ol; + } +function AnchorPosition_getWindowOffsetLeft (el) { + return AnchorPosition_getPageOffsetLeft(el)-document.body.scrollLeft; + } +function AnchorPosition_getPageOffsetTop (el) { + var ot=el.offsetTop; + while((el=el.offsetParent) != null) { ot += el.offsetTop; } + return ot; + } +function AnchorPosition_getWindowOffsetTop (el) { + return AnchorPosition_getPageOffsetTop(el)-document.body.scrollTop; + } |
