我试图编写一个登录到网站的 Node 功能,但无法使其正常工作。我正在尝试使用this post中引用的isElementPresent
函数加载页面,但似乎无法正常工作。
这是我到目前为止的内容:
const webdriver = require('selenium-webdriver')
const By = webdriver.By
var username = ''
var password = ''
var timeout = 5000
function FacebookLogin(username, password) {
var driver = new webdriver.Builder()
.withCapabilities(webdriver.Capabilities.chrome())
.build()
driver.get('http://www.facebook.com')
driver.wait(function() {
return driver.isElementPresent(By.id('email'))
}, timeout)
var user = driver.findElement(By.id('email'))
user.sendKeys(username)
var pass = driver.findElement(By.id('pass'))
pass.sendKeys(password)
pass.submit()
driver.sleep(5000)
driver.quit()
}
FacebookLogin(username, password)
当我运行函数时,我收到错误
TypeError: driver.isElementPresent is not a function
。这是怎么回事,我想念什么? 最佳答案
For consistency with the other Selenium language bindings, WebDriver#isElementPresent()
and WebElement#isElementPresent()
have been deprecated.
如果您使用的是Selenium 3
,则应尝试使用findElements
来确定元素是否存在,如下所示:-
driver.findElements(By.id('email')).then(found => !!found.length);
或者,如果您要等到欲望元素出现,则应尝试使用
webdriver.until
,如下所示:-const until = webdriver.until;
var user = driver.wait(until.elementLocated(By.id('email')), timeout);
user.sendKeys(username);
