# `window.open` Function
|
|
|
|
> Open a new window and load a URL.
|
|
|
|
When `window.open` is called to create a new window in a web page, a new instance
|
|
of `BrowserWindow` will be created for the `url` and a proxy will be returned
|
|
to `window.open` to let the page have limited control over it.
|
|
|
|
The proxy has limited standard functionality implemented to be
|
|
compatible with traditional web pages. For full control of the new window
|
|
you should create a `BrowserWindow` directly.
|
|
|
|
The newly created `BrowserWindow` will inherit the parent window's options by
|
|
default. To override inherited options you can set them in the `features`
|
|
string.
|
|
|
|
### `window.open(url[, frameName][, features])`
|
|
|
|
* `url` String
|
|
* `frameName` String (optional)
|
|
* `features` String (optional)
|
|
|
|
Returns [`BrowserWindowProxy`](browser-window-proxy.md) - Creates a new window
|
|
and returns an instance of `BrowserWindowProxy` class.
|
|
|
|
The `features` string follows the format of standard browser, but each feature
|
|
has to be a field of `BrowserWindow`'s options.
|
|
|
|
**Notes:**
|
|
|
|
* Node integration will always be disabled in the opened `window` if it is
|
|
disabled on the parent window.
|
|
* Non-standard features (that are not handled by Chromium or Electron) given in
|
|
`features` will be passed to any registered `webContent`'s `new-window` event
|
|
handler in the `additionalFeatures` argument.
|
|
|
|
### `window.opener.postMessage(message, targetOrigin)`
|
|
|
|
* `message` String
|
|
* `targetOrigin` String
|
|
|
|
Sends a message to the parent window with the specified origin or `*` for no
|
|
origin preference.
