Question

我尝试使用 driver.find_element_by_partial_link_text（'2019'）但我收到一条错误消息，说它找不到元素。我也尝试过使用find_element_by_link_text（''）并使用整行，但是它行不通。想法？

driver.find_element_by_partial_link_text('2019').click()

这就是我一直在尝试而没有做的事情。这是HTML页面：

Answer 1

在示例HTML中，“ 2019”的唯一实例位于<h2>标记中，而不是锚点（<a>）链接中。由于find_element_by_partial_link_text()仅搜索锚标记，因此找不到。

您可以通过XPath搜索以通过部分文本找到任意元素。像这样：

all_matches = driver.find_elements_by_xpath("//*[text()[contains(., '2019')]]")
all_matches[0].click()

该XPath说：

搜索所有个元素（*）
依次查看每个项目的text()
如果该text() contains()字符串“ 2019”，则将其添加到匹配项中。

当然，我们只单击匹配的 first 元素。

Answer 2

代替使用driver.findElement（By.partialLinkText（“ 2019”））; 您应该使用driver.findElement（By.linkText（“ 2019”））; 再次无效，因为许多calander的链接文本为2019。因此，您需要提供一个特定的名称。例如，我这样做：-

import org.openqa.selenium.By;
import org.openqa.selenium.Keys;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
public class AmazonShoping {

    public static void main(String[] args) 
    {
        System.setProperty("webdriver.chrome.driver","C:\\Users\\priyj_kumar\\Downloads\\chromedriver.exe");
        WebDriver driver = new ChromeDriver();
        driver.get("https://www.amazon.in");
        driver.findElement(By.id("twotabsearchtextbox")).sendKeys("2019 Calander",Keys.ENTER);
        driver.findElement(By.linkText("mapyourmonth Planner Organizer Diary Wall Calendar 2019")).click();
        //checking for a particular boat headphone say Boat BassHeads 900 Wired Headphone with Mic
//      driver.findElement(By.linkText("Boat BassHeads 900 Wired Headphone with Mic")).click();
//      String str = driver.findElement(By.xpath("//*[@id='mp-tfa']/p")).getText();
//      System.out.println(str);
    }

}

这对我来说很好。如果我以某种方式误解了这个问题，请告诉我。
