新建一个 tab.

这是一个异步函数,返回 Promise.

语法

var creating = browser.tabs.create(
  createProperties   // object
)

参数

createProperties
object. Properties to give the new tab. To learn more about these properties, see the {{WebExtAPIRef("tabs.Tab")}} documentation.
active{{optional_inline}}
boolean. Whether the tab should become the active tab in the window. Does not affect whether the window is focused (see {{WebExtAPIRef('windows.update')}}). Defaults to true.
cookieStoreId {{optional_inline}}
string. Use this to create a tab whose cookie store ID is cookieStoreId. This option is only available if the extension has the "cookies" permission.
index{{optional_inline}}
integer. The position the tab should take in the window. The provided value will be clamped to between zero and the number of tabs in the window.
openerTabId{{optional_inline}}
integer. The ID of the tab that opened this tab. If specified, the opener tab must be in the same window as the newly created tab.
openInReaderMode{{optional_inline}}
boolean. If true, open this tab in Reader Mode. Defaults to false.
pinned{{optional_inline}}
boolean. Whether the tab should be pinned. Defaults to false.
selected{{optional_inline}}
boolean. Whether the tab should become the selected tab in the window. Defaults to true.
This property is deprecated, and is not supported in Firefox. Use active instead.
url{{optional_inline}}
string. The URL to navigate the tab to initially. Defaults to the New Tab Page.
Fully-qualified URLs must include a scheme (i.e. 'http://www.google.com', not 'www.google.com').
For security reasons, in Firefox, this may not be a privileged URL. So passing any of the following URLs will fail:
  • chrome: URLs
  • javascript: URLs
  • data: URLs
  • file: URLs (i.e., files on the filesystem. However, to use a file packaged inside the extension, see below)
  • privileged about: URLs (for example, about:config, about:addons, about:debugging). Non-privileged URLs (e.g., about:blank) are allowed.
  • The New Tab page (about:newtab) can be opened if no value for URL is provided.

To load a page that's packaged with your extension, specify an absolute URL starting at the extension's manifest.json file. For example: '/path/to/my-page.html'. If you omit the leading '/', the URL is treated as a relative URL, and different browsers may construct different absolute URLs.

windowId{{optional_inline}}
integer. The window to create the new tab in. Defaults to the current window.

返回值

A Promise that will be fulfilled with a {{WebExtAPIRef('tabs.Tab')}} object containing details about the created tab. If the tab could not be created (for example, because url used a privileged scheme) the promise will be rejected with an error message.
