<p>新建一个 tab.</p>
<p>这是一个异步函数,返回 <code><a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise">Promise</a></code>.</p>
<h2 id="语法">语法</h2>
<pre class="syntaxbox brush:js">var creating = browser.tabs.create(
createProperties // object
)
</pre>
<h3 id="参数">参数</h3>
<dl>
<dt><code>createProperties</code></dt>
<dd><code>object</code>. Properties to give the new tab. To learn more about these properties, see the {{WebExtAPIRef("tabs.Tab")}} documentation.</dd>
<dd>
<dl class="reference-values">
<dt><code>active</code>{{optional_inline}}</dt>
<dd><code>boolean</code>. 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 <code>true</code>.</dd>
<dt><code>cookieStoreId</code> {{optional_inline}}</dt>
<dd><code>string</code>. Use this to create a tab whose cookie store ID is <code>cookieStoreId</code>. This option is only available if the extension has the <code>"cookies"</code> <a href="https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/manifest.json/permissions">permission</a>.</dd>
<dt><code>index</code>{{optional_inline}}</dt>
<dd><code>integer</code>. 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.</dd>
<dt><code>openerTabId</code>{{optional_inline}}</dt>
<dd><code>integer</code>. 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.</dd>
<dt><code>openInReaderMode</code>{{optional_inline}}</dt>
<dd><code>boolean</code>. If <code>true</code>, open this tab in <a href="/en-US/Add-ons/WebExtensions/API/tabs/toggleReaderMode">Reader Mode</a>. Defaults to <code>false</code>.</dd>
<dt><code>pinned</code>{{optional_inline}}</dt>
<dd><code>boolean</code>. Whether the tab should be pinned. Defaults to <code>false</code>.</dd>
<dt><code>selected</code>{{optional_inline}}</dt>
<dd><code>boolean</code>. Whether the tab should become the selected tab in the window. Defaults to <code>true</code>.
<div class="warning">This property is deprecated, and is not supported in Firefox. Use <code>active</code> instead.</div>
</dd>
<dt><code>url</code>{{optional_inline}}</dt>
<dd><code>string</code>. The URL to navigate the tab to initially. Defaults to the New Tab Page.</dd>
<dd>Fully-qualified URLs must include a scheme (i.e. 'http://www.google.com', not 'www.google.com').</dd>
<dd>For security reasons, in Firefox, this may not be a privileged URL. So passing any of the following URLs will fail:</dd>
<dd>
<ul>
<li>chrome: URLs</li>
<li>javascript: URLs</li>
<li>data: URLs</li>
<li>file: URLs (i.e., files on the filesystem. However, to use a file packaged inside the extension, see below)</li>
<li>privileged about: URLs (for example, <code>about:config</code>, <code>about:addons</code>, <code>about:debugging</code>)<span class="hidden"> </span>. Non-privileged URLs (e.g., <code>about:blank</code>) are allowed.</li>
<li>The New Tab page (<code>about:newtab</code>) can be opened if no value for URL is provided.</li>
</ul>
<p>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.</p>
</dd>
<dt><code>windowId</code>{{optional_inline}}</dt>
<dd><code>integer</code>. The window to create the new tab in. Defaults to the current window.</dd>
</dl>
</dd>
</dl>
<h3 id="返回值">返回值</h3>
<p>A <code><a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise">Promise</a></code> 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 <code>url</code> used a privileged scheme) the promise will be rejected with an error message.</p>
