windows.update() 编辑

Updates the properties of a window. Use this to move, resize, and (un)focus a window, etc.

This is an asynchronous function that returns a Promise.

Syntax

var updating = browser.windows.update(
  windowId,              // integer
  updateInfo             // object
)

Parameters

windowId

integer. ID of the window to update.

updateInfo

object. Object containing the properties to update.

drawAttention Optional

boolean. If true, causes the window to be displayed in a manner that draws the user's attention to the window, without changing the focused window. The effect lasts until the user changes focus to the window. This option has no effect if the window already has focus. Set to false to cancel a previous drawAttention request.

focused Optional

boolean. If true, brings the window to the front. If false, brings the next window in the z-order to the front.

height Optional

integer. The height to resize the window to in pixels. This value is ignored for panels.

left Optional

integer. The offset from the left edge of the screen to move the window to in pixels. This value is ignored for panels.

state Optional

windows.WindowState. The new state of the window. The minimized, maximized and fullscreen states cannot be combined with left, top, width or height.

titlePreface Optional

string. Use this to add a string to the beginning of the browser window's title. Depending on the underlying operating system, this might not work on browser windows that don't have a title (such as about:blank in Firefox).

top Optional

integer. The offset from the top edge of the screen to move the window to in pixels. This value is ignored for panels.

width Optional

integer. The width to resize the window to in pixels. This value is ignored for panels.

Return value

A Promise that will be fulfilled with a windows.Window object containing the details of the updated window. If any error occurs, the promise will be rejected with an error message.

Browser compatibility

BCD tables only load in the browser

Examples

When the user clicks a browser action's icon, move the window to the top left corner:

function onUpdated(windowInfo) {
  console.log(`Updated window: ${windowInfo.id}`);
}

function onError(error) {
  console.log(`Error: ${error}`);
}

browser.browserAction.onClicked.addListener((tab) => {

  var updating = browser.windows.update(tab.windowId, {
    left: 0,
    top: 0
  });
  updating.then(onUpdated, onError);

});
