java - Selenium 无法识别弹出窗口上的对象

Question

大家好，有人可以帮助我为什么我无法选择“从帐户中删除”按钮。如果您查看屏幕截图， Selenium 会成功单击显示弹出窗口的星号。然后我希望 Selenium 单击“从帐户中删除”按钮，但它不起作用。感谢任何帮助

这是我的代码:

public void clickSpecialPricingRemoveFromAccount(){
webDriver.findElement(By.xpath("//*[@id='singleProductTR']/td[6]/div/div[2]/div/div/div/div[2]/button[1])")).click();
}

我收到的错误消息是:

org.openqa.selenium.InvalidSelectorException: The given selector //[@id='singleProductTR']/td[6]/div/div[2]/div/div/div/div[2]/button[1]) is either invalid or does not result in a WebElement. The following error occurred: InvalidSelectorError: Unable to locate an element with the xpath expression //[@id='singleProductTR']/td[6]/div/div[2]/div/div/div/div[2]/button[1]) because of the following error: SyntaxError: The expression is not a legal expression.

org.openqa.selenium.InvalidSelectorException: The given selector //[@id='singleProductTR']/td[6]/div/div[2]/div/div/div/div[2]/button[1]) is either invalid or does not result in a WebElement

您提供的 xpath 看起来语法不正确，应该是:-

//*[@id='singleProductTR']/td[6]/div/div[2]/div/div/div/div[2]/button[1]

您已在末尾附加了 ) 和此 xpath，但本不应该出现在此处。

但是您可以使用更具体的 xpath 来代替，使用 innerText 会更稳定，如下所示:-

webDriver.findElement(By.xpath(".//button[text() = 'Remove from Account']").click();
