使用Selenium Webdriver选择下拉菜单选项的不同方法有哪些?
使用Selenium webdriver选择下拉菜单选项的方法有很多。这可以通过Select类来实现。HTML代码中的下拉菜单由select标签表示。
下拉菜单中的选项由option标签表示。此外,为了使用下拉菜单,需要在代码中添加语句org.openqa.selenium.support.ui.Select。
从下拉菜单中选择选项的不同方法如下:
selectByIndex – 将下拉菜单中要选择的选项的索引作为参数传递。索引从0开始。
WebElement e = driver.findElement(By.className("opt")); Select s = new Select(e); s.selectByIndex(0);
selectByValue – 将下拉菜单中要选择的选项的value属性作为参数传递。下拉菜单中的选项应具有value属性才能使用此方法。
WebElement e = driver.findElement(By.className("opt")); Select s = new Select(e); s.selectByIndex("option 1");
selectByVisibleText – 将下拉菜单中要选择的选项的可视文本作为参数传递。
WebElement e = driver.findElement(By.className("opt")); Select s = new Select(e); s.selectByVisibleText("Selenium");
让我们尝试从下面的下拉菜单中选择一个选项:
示例
使用selectByIndex的代码实现
import org.openqa.selenium.By; import org.openqa.selenium.WebDriver; import org.openqa.selenium.WebElement; import org.openqa.selenium.firefox.FirefoxDriver; import java.util.concurrent.TimeUnit; import org.openqa.selenium.support.ui.Select public class DrpSelectByIndex{ public static void main(String[] args) { System.setProperty("webdriver.gecko.driver", "C:\Users\ghs6kor\Desktop\Java\geckodriver.exe"); WebDriver driver = new FirefoxDriver(); //implicit wait driver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS); //URL launch driver.get("https://tutorialspoint.com/tutor_connect/index.php/"); //identify dropdown WebElement n = driver.findElement(By.name("selType")); //select option by index Select s = new Select(n); s.selectByIndex(0); driver.quit(); } }
使用selectByValue的代码实现
import org.openqa.selenium.By; import org.openqa.selenium.WebDriver; import org.openqa.selenium.WebElement; import org.openqa.selenium.firefox.FirefoxDriver; import java.util.concurrent.TimeUnit; import org.openqa.selenium.support.ui.Select public class DrpSelectByValue{ public static void main(String[] args) { System.setProperty("webdriver.gecko.driver", "C:\Users\ghs6kor\Desktop\Java\geckodriver.exe"); WebDriver driver = new FirefoxDriver(); //implicit wait driver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS); //URL launch driver.get("https://tutorialspoint.com/tutor_connect/index.php/"); //identify dropdown WebElement n = driver.findElement(By.name("selType")); //select option by value attribute of option Select s = new Select(n); s.selectByValue("subject"); driver.quit(); } }
使用selectByVisibleText的代码实现
import org.openqa.selenium.By; import org.openqa.selenium.WebDriver; import org.openqa.selenium.WebElement; import org.openqa.selenium.firefox.FirefoxDriver; import java.util.concurrent.TimeUnit; import org.openqa.selenium.support.ui.Select public class DrpSelectByVisibleTxt{ public static void main(String[] args) { System.setProperty("webdriver.gecko.driver", "C:\Users\ghs6kor\Desktop\Java\geckodriver.exe"); WebDriver driver = new FirefoxDriver(); //implicit wait driver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS); //URL launch driver.get("https://tutorialspoint.com/tutor_connect/index.php/"); //identify dropdown WebElement n = driver.findElement(By.name("selType")); //select option by value attribute of option Select s = new Select(n); s.selectByVisibleText("By Name"); driver.quit(); } }
