硒通过css而不是id搜索元素

Question

今天我更新我的铬驱动程序

If you are using Chrome version 77, please download ChromeDriver 77.0.3865.40

我尝试使用以下代码通过 id 查找元素：

public static void inputValueById(String input,String id)
{
WebDriver driver2 = WebDriverMgr.getDriver();
WebElement element = driver2.findElement(By.id("//input[@id='company']"));
element.click();
element.clear();
element.sendKeys(input);
}

我得到这个例外

ERROR: no such element: Unable to locate element: {"method":"css selector","selector":"#//input[@id='company']"}
(Session info: chrome=77.0.3865.90)

有人可以告知为什么它通过 css 选择器而不是通过 ID 进行搜索吗？ 方法"："css 选择器">

Answer 1

我认为当您尝试通过其ID查找元素时，您必须像这样编写代码：

driver.findElement(By.id("ID"))

如果你想用这个xpath找到，你必须这样写：

driver.findElements(By.xpath("//input[@id='company']"));
