# `window.open` function
|
|
|
|
When `window.open` is called to create a new window in 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 only has some limited standard functionality implemented to be
|
|
compatible with traditional web pages, for full control of the created window
|
|
you should create a `BrowserWindow` directly.
|
|
|
|
## window.open(url, [frameName[, features]])
|
|
|
|
* `url` String
|
|
* `frameName` String
|
|
* `features` String
|
|
|
|
Creates a new window and returns an instance of `BrowserWindowProxy` class.
|
|
|
|
## 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.

|

* `message` String

In addition to these methods, the child window implements `window.opener` object
|
|
with no properties and a single method:
