问题描述
我正在编制基于
这是创建边栏（界面面板）的代码：
sidebars.js ：
/ **
* createInterfacePanelIframe（location，options）
* < iframe>在
*当前窗口中的当前选项卡内的基于窗口的面板，或者打开一个窗口，用作用户界面
*框。如果它不是一个窗口，它将与当前的
*浏览器标签或当前的浏览器窗口相关联，具体取决于
* byWindow选项。
* @param location
*放置面板[right | left | top | bottom | window]
*默认位置是'right'。
* @param选项
*包含可选参数的对象。
* height
*顶部或底部边栏的高度
*默认为200.
* width
*左边或右边栏的宽度
*默认值为200.
* size
*如果在左边或右边的宽度。如果顶部或底部高度。
*如果位置=窗口，则宽度和高度都不相同，除非
* features是一个字符串。
*默认为200.
* id
*要分配给iframe的ID。默认是
*'makyen-interface-panel'
*< splitter>将分配
* ID = id +'-splitter'
* url
*这是用于iframe内容
*的chrome：// URL窗户。
*缺省值是：
*'chrome：//devtools/content/framework/toolbox.xul'
* iframeAttributes
*一个对象
*包含键/值对应用于iframe的属性
*。这些将覆盖从其他选项（例如id，height，
* width，type等）派生的任何默认值或其他
*属性。如果该属性的值为空
*，那么该属性将被删除。
* useBrowser
*如果为true，则< browser>元素被用来代替< iframe> ;.
* byWindow
*如果为true，那么创建的侧边栏是窗口
*而不是标签。
* tab
*要为其创建边栏的选项卡。如果未指定
*，则使用当前选项卡。
*窗口
*要为其创建边栏的窗口。如果未指定
*，则使用当前窗口。
*特征
*窗口的特征字符串。请参阅：

The code in this answer was adapted and significantly expanded from my answer to \"\". That answer has significant additional information as how sidebars (interface panels) are structured within the Firefox Browser.
I'm programming a Firefox Add-on SDK based extension. I need to use both a left and a right-side sidebar, at the same time. By default, I can display one on the left side. I've already read about changing between having the ui/sidebar on the left and the right by using the CSS:
@namespace url(http://www.mozilla.org/keymaster/gat...re.is.only.xul);
hbox#browser {
direction: rtl !important;
}
hbox#browser > vbox {
direction: ltr !important;
}
But, that seems to be something of the old-school, because I didn't define .xul files.
Do you know any to have a sidebar on both the left and right of the browser at the same time?
解决方案
Your question is not clear as to exactly what you want. Thus, I have made some assumptions.
Ultimately, there is no officially supported way to have more than one "sidebar" displayed at a time. By default, only a single "sidebar" exist within the Firefox Browser windows. While there is no supported API which provides you with more than one sidebar, it is possible to create multiple sidebars (interface panels) by modifying the XUL DOM for the Firefox Browser windows.
The code below creates user interface panels (side-bars, top-bars, bottom-bars and windows) which are on the top, bottom, left, right, of the browser window, or in a separate window. The interface panels can be created such that they are with respect to the window (they stay visible when you switch tabs; like a bookmarks/history sidebar), or are with respect to the tab (they on only visible when the tab in which they were created is displayed; like the developer tools).
The createInterfacePanelIframe() method creates an interface panel containing an <iframe> (or <browser>) for which you can supply the URL and all attributes. The elements for the <iframe> and the <splitter> are returned to the caller so you can perform other operations on them, or remove them from the Firefox window's DOM to delete/hide them. This method creates <iframe> and calls createInterfacePanel() to insert it into the Firefox browser in the location specified.
The createInterfacePanel() method will put the XUL element that you pass to it (use a Document Fragment to pass multiple elements) into the Firefox Browser window's DOM, along with a <splitter> in the location specified (left, right, top, bottom, window and relative to either the window or the tab). You can specify the window and/or tab you desire the interface panel to be within, or, by default, the interface panel is inserted in the current window/tab. If an interface panel already exists where you are specifying one to be inserted, another panel will be created adjacent to the existing one. There is no inherent limit to the number you can create (e.g. you could have 10 panels on the right, if you wanted).
In addition, a demo Firefox Add-on SDK extension is below which adds 6 different buttons. The first 5 buttons create or destroy interface panels. The badge indicates which panel the button will affect (left, right, top, bottom, and window). A green badge indicates an interface panel will be created. A red badge indicates clicking will destroy the already existing panel. The sixth button toggles the other buttons between Tab relative interface panels, and Window relative interface panels. If you create all the panels your will have 8 panels (4 for the Window and 4 for the current tab) along with two separate windows (per Browser Window).
The following is what the demo add-on looks like. The panels shown in the image below are narrow and/or short to allow them to be displayed on this page. The code below allows you to make the panels whatever size you desire and for the user to be able to resize them.
This is the code which creates the sidebars (interface panels):
sidebars.js:
/**
* createInterfacePanelIframe(location,options)
* Creates an <iframe> based panel within the current tab, within the
* current window, or opens a window, for use as an user interface
* box. If it is not a window, it is associated with the current
* browser tab, or the current browser window depending on the
* byWindow option.
* @param location
* Placement of the panel [right|left|top|bottom|window]
* The default location is 'right'.
* @param options
* An Object containing optional parameters.
* height
* The height of a top or bottom sidebar
* Default is 200.
* width
* The width of a left or right sidebar
* Default is 200.
* size
* Width if on left or right. Height if top or bottom.
* Both width and height if location='window' unless
* features is a string.
* Default is 200.
* id
* The ID to assign to the iframe. Default is
* 'makyen-interface-panel'
* The <splitter> will be assigned the
* ID = id + '-splitter'
* url
* This is the chrome:// URL to use for the contents
* of the iframe or the window.
* the default is:
* 'chrome://devtools/content/framework/toolbox.xul'
* iframeAttributes
* An Object
* Contains key/value pairs which are applies as attributes
* of the iframe. These will override any defaults or other
* attributes derived from other options (e.g. id, height,
* width, type, etc.). If the value of the property is null
* then that attribute will be removed.
* useBrowser
* If true, a <browser> element is used instead of an <iframe>.
* byWindow
* If true then the created sidebar is for the window
* not the tab.
* tab
* The tab for which to create the sidebar. If not
* specified, the current tab is used.
* window
* The window for which to create the sidebar. If not
* specified, the current window is used.
* features
* The features string for the window. See:
* https://developer.mozilla.org/en-US/docs/Web/API/Window.open
*
* returns [splitterEl, iframeEl]
* The elements for the <splitter> and <iframe>.

/**
* createInterfacePanel(location,objectEl,options)
* Creates a panel within the current tab, or opens a window, for use as a
* user interface box. If not a window, it is associated with the current
* browser tab.
* @param location
* Placement of the panel [right|left|top|bottom|window]
* The default location is 'right'.
* @param objectEl
* The element of an XUL object that will be inserted into
* the DOM such that it is within the current tab.
* Some examples of possible objects are <iframe>,
* <browser>, <box>, <hbox>, <vbox>, etc.
* If the location='window' and features is not a string
* and this is a number then it is used as the width of the
* window.
* @param options
* An Object containing optional parameters.
* height
* The height of a top or bottom sidebar
* Default is 200.
* width
* The width of a left or right sidebar
* Default is 200.
* size
* Width if on left or right. Height if top or bottom.
* Both width and height if location='window' unless
* features is a string.
* Default is 200.
* If none of height, width or size is specified, then the
* size of the sidebar should be specified within the XUL
* elements referenced by objectEl.
* sizeEl
* The element that is to contain attributes of 'width' and
* 'height'. If location=='left'|'right' then the
* 'height' attribute is removed prior to the objectEl
* being inserted into the DOM.
* This is an optional spearate reference for the size element
* in case the objectEl is a documentFragment containing
* multiple elements. However, normal usage is for
* objectEl === sizeEl (which is default if unspecified)
* when location != 'window'.
* When location == 'window' and features is not a string,
* and sizeEl is a number then it is used as the height
* of the window.
* If features is a string, it is assumed the height is
* set in that, or elsewhere (e.g. in the XUL).
* id
* The ID to assign to the <splitter>. The default is:
* 'makyen-interface-panel-splitter'.
* url
* This is the chrome:// URL to use for the contents
* of the window.
* the default is:
* 'chrome://devtools/content/framework/toolbox.xul'
* byWindow
* If true then the created sidebar is for the window
* not the tab.
* tab
* The tab for which to create the sidebar. If not
* specified, the current tab is used.
* window
* The window for which to create the sidebar. If not
* specified, the current window is used.
* features
* The features string for the window. See:
* https://developer.mozilla.org/en-US/docs/Web/API/Window.open
* If features is a string, it is assumed the width is
* set in that, or elsewhere (e.g. in the XUL).
*
* returns
* if location != 'window':
* splitterEl, The element for the <splitter>.
* if location == 'window':
* The windowObjectReference returned by window.open().

The code in this answer was adapted and significantly expanded from my answer to "Firefox Extension, Window related sidebar". That answer has significant additional information as how sidebars (interface panels) are structured within the Firefox Browser.
