我有一个HTML href链接
<a class="btn btn-icon-text btn-secondary" data-toggle="modal" data-target="#recordSharingDownloadModal" href="/person/mL7CD8tR59g2Cy2/health-record/sharing/media/clinical-summary/%7B7c-06-74-be-dc-67-47-5d-be-92-4c-58-5a-fd-1b-8f%7D/download-options/" title="Download Document">Download</a>
使用硒,我需要单击链接。目前,我正在使用以下代码-
driver.findElement(By.xpath("//a[contains(@href='/person/mL7CD8tR59g2Cy2/health-record/sharing/media/clinical-summary/%7B7c-06-74-be-dc-67-47-5d-be-92-4c-58-5a-fd-1b-8f%7D/download-options/')]")).click();
但是它抛出一个错误
“ java.lang.NullPointerException”
我也尝试过使用CssSelector单击按钮,但仍然是相同的错误。我需要单击“临床摘要”部分下的“下载”按钮,但是有多个具有相同按钮名称的部分。只有HREF是唯一的。
谁能帮帮我吗?
这段代码:
package LaunchIQHealth;
import java.io.File;
import java.io.IOException;
import org.apache.commons.io.FileUtils;
import org.openqa.selenium.By;
import org.openqa.selenium.JavascriptExecutor;
import org.openqa.selenium.OutputType;
import org.openqa.selenium.TakesScreenshot;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.support.ui.*;
public class AutomateIQHealth
{
public static void main(String[] args) throws IOException, InterruptedException
{
System.setProperty("webdriver.chrome.driver", "C:\\Users\\abc\\Desktop\\chromedriver.exe");
WebDriver driver = new ChromeDriver();
WebDriverWait wait = new WebDriverWait(driver, 20);
driver.get("url");
((JavascriptExecutor)driver).executeScript("scroll(0,400)").equals("Clinical Summaries");
wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//*[contains(text(), 'Download")));
driver.findElements(By.xpath("//a[@href='/person/mL7CD8tR59g2Cy2/health-record/sharing/media/clinical-summary/%7B7c-06-74-be-dc-67-47-5d-be-92-4c-58-5a-fd-1b-8f%7D/download-options/']")).get(0).click();
}
}
最佳答案
如果我认为您当前粘贴的代码是正确的代码,则您将无法执行以下任一操作:
driver.findElement(By.xpath("//a[contains(@href='/person/mL7CD8tR59g2Cy2/health-record/sharing/media/clinical-summary/%7B7c-06-74-be-dc-67-47-5d-be-92-4c-58-5a-fd-1b-8f%7D/download-options/')]")).click();
要么
driver.findElements(By.xpath("//a[@href='/person/mL7CD8tR59g2Cy2/health-record/sharing/media/clinical-summary/%7B7c-06-74-be-dc-67-47-5d-be-92-4c-58-5a-fd-1b-8f%7D/download-options/']")).get(0).click();
原因是,
chromedriver
很高兴为您打开Chrome Browser
,但是您尝试了executeScript("scroll(0,400)").equals("Clinical Summaries");
,但是按照documentation JavascriptExecutor
(它是Interface
)以及关联的方法executeScript
和无法调用executeAsyncScript
方法。
