DOM improvements in Firefox 3
Firefox 3 offers a number of improvements to the Document Object Model (DOM), especially in regard to support for extensions to the DOM added by other browsers. This article provides a list of those improvements as well as links to more detailed documentation.
- The Internet Explorer
clientTop
andclientLeft
DOM extensions are now supported. - The
window.fullScreen
property is now always accurate no matter where it is read, even in content. Previously it would returnfalse
inaccurately (Firefox bug 127013). - The
getClientRects
andgetBoundingClientRect
DOM extensions are now supported (see Firefox bug 174397). - The Internet Explorer
elementFromPoint
DOM extension is now supported (Firefox bug 199692). - The Internet Explorer
oncut
,oncopy
, andonpaste
DOM extensions are now supported (Firefox bug 280959). - Added privileged-code-only getters for
Node.nodePrincipal
,Node.baseURIObject
, anddocument.documentURIObject
. Chrome code must not touch (get or set) these properties on an unwrapped content object (e.g. on awrappedJSObject
of anXPCNativeWrapper
), see Firefox bug 324464 for details. - The Web Applications 1.0 (HTML5)
getElementsByClassName()
DOM method is now supported. - The Web Applications 1.0 (HTML5)
window.postMessage
DOM method is now supported. This method allows a limited, opt-in form of client-side communication between windows not necessarily on the same domain. - The
charCode
value of thekeypress
event is changed to an ASCII character if the accelerator key is pressed. Otherwise thecharCode
is the unmodified character (exceptingShift
state). See Gecko Keypress Event.
