Firefox 21 for developers
Web 开发者需要注意的变化
HTML
- 实现了
<style>
元素上的scoped
属性。拥有该属性的<style>
元素可以通过在 Firefox 20 中实现的 CSS 伪类:scope
选择器选择到.(Firefox bug 508725). - 实现了新的
<main>
元素 (Firefox bug 820508).
JavaScript
- E4X,一个古老的 JavaScript 扩展 (ECMA-357),已经被删除。因为一直以来,只有 Gecko 支持它.(Firefox bug 788293).
- parseInt (en-US)不再将以"0"开头的字符串作为 8 进制数字来解析 (Firefox bug 786135).
CSS
-moz-user-select
属性的属性值在设置为none
时和设置为-moz-none
时效果等同于,这样才能让 Gecko 和其他内核 WebKit(Chrome, Safari),Presto (Opera) 以及 Trident(Internet Explorer) 中的表现相同 (Firefox bug 816298).- On XHTML content, the
auto
value of-moz-hyphens
incorrectly applied hyphenation rules when the language was not explicitly declared. This is fixed by (Firefox bug 702121). - CSS 属性
-moz-orient
(en-US)现在支持新的值auto
. 当应用到一个<meter>
元素或者<progress>
元素上时,auto
就等同于horizontal
(Firefox bug 835883).
DOM
- 实现了
window.location
上的origin
属性 (Firefox bug 828261). - 实现了
<input type="time">
对象上的valueAsDate
和valueAsNumber
方法 (Firefox bug 781570). - 实现了
<input type="time">
对象上的min
和max
属性 (Firefox bug 781572). - Some new keyCodes for volume control are supported (Firefox bug 674739).
- Some new keyCodes for ancient keyboard layout such as AS/400 are now supported on Windows and Linux (Firefox bug 833719).
- Various keyCode values for OEM sepecific keys on Windows are now supported again (Firefox bug 833719).
- 实现了
window.crypto.getRandomValues
函数 (Firefox bug 440046)。
SVG
- 实现了
paint-order
属性 (Firefox bug 828805).
网络
- 更新 CSP 实现到最新的 CSP 规范 1.0(CR):
- Support for the spec-compliant
Content-Security-Policy
HTTP header (in addition to the experimentalX-Content-Security-Policy
) has been added (Firefox bug 783049). Note: the patch for this new header landed in Firefox 21, it is disabled on builds (Firefox bug 842657).
- Support for the spec-compliant
附加组件和 Mozilla 开发者需要注意的变化
- FUEL applications cannot use the Livemarks service anymore (Firefox bug 834492). The Livemarks service is deprecated and phased out in favor of the new async interface.
- History API saw numerous deprecated API being removed:
- Replaced by
mozIAsyncFavicons
:nsIFaviconService::setFaviconUrlForPage
nsIFaviconService::setFaviconData
nsIFaviconService::getFaviconData
nsIFaviconService::getFaviconForPage
nsIFaviconService::setAndLoadFaviconForPage
nsIFaviconService::getFaviconImageForPage
nsIFaviconService::getFaviconDataAsDataURL
- Replaced by
mozIAsyncLivemarks
:nsILivemarkService::*
PlacesUtils.itemIsLivemark
PlacesUtils.nodeIsLivemarkContainer
PlacesUtils.nodeIsLivemarkItem
- Removed only third argument:
PlacesUIUtils.showBookmarkDialog
- No more implemented by Places, use
mozIAsyncHistory
instead:nsIGlobalHistory2::addURI
nsIGlobalHistory2::isVisited
nsIGlobalHistory2::setPageTitle
- No more needed, use
onDeleteURI
oronItemRemoved
:nsINavHistoryObserver::OnBeforeDeleteURI
nsINavBookmarkObserver::OnBeforeItemRemoved
- Never implemented properly:
nsINavHistoryFullVisitResultNode
- Deprecated, use
mozIAsyncHistory::updatePlaces
