*
|

* @description
|
||||
* Prevent a webpage from opening new tabs through `window.open()`.
|
||||
*
|
||||
* @param pattern
|
||||
* A plain string or regex to match against the `url` argument for the
|
||||
* prevention to be triggered. If not provided, all calls to `window.open()`
|
||||
* are prevented.
|
||||
* If set to the special value `debug` *and* the logger is opened, the scriptlet
|
||||
* will trigger a `debugger` statement and the prevention will not occur.
|
||||
*
|
||||
* @param [delay]
|
||||
* If provided, a decoy will be created or opened, and this parameter states
|
||||
* the number of seconds to wait for before the decoy is terminated, i.e.
|
||||
* either removed from the DOM or closed.
|
||||
*
|
||||
* @param [decoy]
|
||||
* A string representing the type of decoy to use:
|
||||
* - `blank`: replace the `url` parameter with `about:blank`
|
||||
* - `object`: create and append an `object` element to the DOM, and return
|
||||
* its `contentWindow` property.
|
||||
* - `frame`: create and append an `iframe` element to the DOM, and return
|
||||
* its `contentWindow` property.
|
||||
*
|
||||
* @example
|
||||
* ##+js(prevent-window-open, ads.example.com/)
|
||||
*
|
||||
* @example
|
||||
* ##+js(prevent-window-open, ads.example.com/, 1, iframe)
