使用Facebook PHP WebDriver在Selenium中执行javascript [英] Execute javascript in Selenium with Facebook PHP WebDriver

问题描述

我正在尝试遵循此文档执行一个脚本，所有我得到的是一个错误，说 executeScript 方法是未定义的。

I am trying to follow this documentation to execute a script, and all I am getting is an error saying the executeScript method is undefined.

$this->driver->navigateTo('/');
$this->driver->clickElement('#member_opt_in + label');
$this->driver->executeScript("alert('Hi');");

该文档使用 $ session ，并说更高的页面，这是速记，但不解释任何地方什么 $ session 实际包含或如何分配。

The documentation uses $session, and says higher up the page that this is shorthand, but doesn't explain anywhere at all what $session actually contains or how to assign it.

推荐答案

wiki on GitHub与当前的php-webdriver库并不是最新版本，并且是指之前（2013年的前期版本）版本，但该库从头开始重写。

The wiki on GitHub is not up-to-date with the current php-webdriver library and refers to previous (pre 2013) version of it - but the library was rewritten from scratch since.

要执行Selenium命令，您需要 RemoteWebDriver 的实例。 自述中可以看到一个例子。

To execute Selenium commands you need instance of RemoteWebDriver. An example can be seen in readme.

使用 RemoteWebDriver 实例在 $ driver 变量可以执行：

With RemoteWebDriver instance in $driver variable you can execute:

$driver->get('http://google.com');

$element = $driver->findElement(WebDriverBy::cssSelector('#member_opt_in + label'));
$elemen->click();

// Execute javascript:
$driver->executeScript('alert("Hi");');
// Or to execute the javascript as non-blocking, ie. asynchronously:
$driver->executeAsyncScript('alert("Hi");');

请参阅 API文档以获取更多信息。
