单击“查看历史”选项卡可查看页面的修订版历史记录。 然后可以选择任意两个版本,然后单击“对比选择的版本”查看差异。 缺少必要权限的用户将无法访问有关修订版本删除的某些数据。
Users can use the Wikiblame tool to search for revisions from a specific author, or character strings in the page of any revision.
Here's what a page history looks like in the default skin.
Let's examine each labeled function:
When a page's name is changed using the move feature, its full edit history which includes a before and after the change is shown on the new page name. The old name optionally becomes a redirect with only its initial history.
When two pages are history merged , one becomes a redirect with no edit history, while the other contains the full edit history of both pages.
Use this URL format to display edits made before a certain UTC date or to limit the number of edits shown:
Or for an earlier date and time specified in UTC:
The second one is in timestamp format.
This happens if someone else made the edit and you haven't seen the page since.
To get Web feeds (RSS and Atom) for a page's history, you can add "&feed=rss" or "&feed=atom" to the URL of the history page. This will show the last 10 edits with links to the full diff page in XML format. Some browsers may offer options like sorting by author (see Syndication).
On a history page list, go to any revision after the second one and click on (当前) for the latest edit. This will show you the changes between that revision edit and the most recent one. Look above the difference table to find the number of intermediate revisions.
Add 2 to that number, and you'll have the total number of revisions in the history.
You can adjust the date format on the history page in your preferences.
Deleting a page is more extreme than just removing content or redirecting the page. When a page is deleted, regular users can't access its history anymore. Consequently, if content has been moved or copied with proper attribution, that attribution is lost when the original page is deleted.
If someone edits a deleted page, their edits won't show up in their usual <tvar name="1">User contributions list. Administrators can still see those edits and restore the deleted page if needed (see w:Wikipedia:Viewing and restoring deleted pages).
Sometimes, when a page is deleted, it's important to decide whether to keep its revision history. If the history should be kept:
A section of a page may be an included separate page (via a method known as ll|Help:Template#Composite_pages), see composite pages . A separate edit history is provided for the section, and this transcluded page must be watched separately. See <tvar name="1">帮助:嵌入 .
You can change or edit an image file by uploading a new one with the same name. All versions of the image are saved, and you can see the history of changes on the image description page.
Sometimes it's helpful to provide a direct link to a particular version of a page. This might be necessary, for instance, if someone has reviewed a Wikipedia article and wants to specify which exact version they reviewed.
You can use the page history to see old versions of a page if it's not the current version. The URL of the old version in the browser's location bar can be used as a permanent reference for that version.
See also Old versions of pages .
Change history to the wikitext aren't the same as change history to the rendered page:
To create a permanent link, save the webpage as an HTML file and provide the URL. This HTML file includes all the template content, so changes or removals of templates won't affect it. However, if images are deleted, it will impact the HTML file.
To create wikitext that doesn't rely on templates, use "subst :" and repeat if needed, or Special:ExpandTemplates
See also m:Help:Downloading pages.
Special:Export creates an XML file containing the wikitext of one or more chosen pages, along with details like date, time, user, and edit summary. How it appears depends on the browser; some may show links to expand or collapse sections. You can also view the XML source directly in your browser or with any program after saving the file locally.
The feature lets you search for text across multiple specified pages. See {{<tvar name="1">ll|Help:Export|XML export}}.
If you don't like the changes you made to your new pages, don't worry. You can revert to any earlier version of the page.
