Question

我正在尝试使用查找元素输入用户名。这是 HTML

<input class="login-input" type="text" placeholder="Username" id="fld_tb_3" tabindex="0" maxlength="128" aria-required="true" aria-labelledby="userLbl" value="">

尽管 id=fld_tb_3 是动态的，并且会在将数据输入字段时发生变化。

这是完整的 xpath

/html/body/div[1]/div/div[1]/div[2]/form/div/div[1]/input

和 xpath

//*[@id="fld_tb_31"]

我正在尝试使用以下代码，但未找到该元素。我什至尝试使用 class 但没有成功。 Class

remDr$findElement(
  using ='xpath', "//div[@class='login-input']/html/body/div[1]/div/div[1]/div[2]/form/div/div[1]/input"
)

通配符

remDr$findElement(
  using ='xpath', "//*[starts-with(@id,'fld_tb_')/div[1]/div/div[1]/div[2]/form/div/div[1]/input"
)

我做错了什么？

添加了错误消息

Answer 1

我们可以做到，

#enter username
user <- remDr$findElement(using = 'xpath', value = '/html/body/div[1]/div/div[1]/div[2]/form/div/div[1]/input')
user$sendKeysToElement(list("my_username"))

#enter passowrd (has to use full xpath)
pass <- remDr$findElement(using = 'xpath', value = '/html/body/div[1]/div/div[1]/div[2]/form/div/div[4]/input')
pass$sendKeysToElement(list("my_password"))

#click on login  
remDr$findElement(using = "xpath",'//*[@id="root"]/div/div[1]/div[2]/form/div/input')$clickElement()

Answer 2

尝试使用用户名的以下 xpath 来识别元素。

//input[@placeholder='Username' and @class='login-input']

因此您的代码将是

 remDr$findElement(
  using ='xpath', "//input[@placeholder='Username' and @class='login-input']"
)

密码元素的 xpath

//input[@placeholder='Password' and @class='login-input']

登录按钮的 xpath

//input[@value='Sign In' and @class='login-button']

RSelenium - NoSuchElement 即使正在使用 xpath？

RSelenium - NoSuchElement even though xpath is being used?
