Java编程语言下Selenium 对于下拉框，单选，多选等选择器的操作

 WebElement selector = driver.findElement(By.id("Selector"));
         Select select = new Select(selector);
         select.selectByIndex(3);
         select.selectByVisibleText("桃子");
         select.selectByValue("apple");

         System.out.println(select.getAllSelectedOptions().toString());
         Thread.sleep(10000);
         WebElement showSelectResult = driver.findElement(By.name("showSelectResult"));
         showSelectResult.click();
         Thread.sleep(10000);
         Alert yourSelect = driver.switchTo().alert();
         Assert.assertTrue(yourSelect.getText().contains("苹果"));
         Thread.sleep(10000);
         yourSelect.accept();

         // for radio Box

         WebElement duRadioBox = driver.findElement(By.cssSelector("div#radio>input.Baidu"));
         WebElement aLiRadioBox = driver.findElement(By.cssSelector("div#radio>input.Alibaba"));
         WebElement TXRadioBox = driver.findElement(By.cssSelector("div#radio>input.Tencent"));
         WebElement MiRadioBox = driver.findElement(By.cssSelector("div#radio>input.Mi"));
         Thread.sleep(10000);
         Assert.assertTrue(TXRadioBox.isSelected());
         Assert.assertTrue(!MiRadioBox.isEnabled());
         Thread.sleep(10000);

         try {

             if (duRadioBox.isEnabled()) {
                 duRadioBox.click();
                 System.out.println("元素被点击");
             }
         } catch (Exception e) {

             System.out.println("点击元素失败。" + e.toString());
         }

         Assert.assertTrue(duRadioBox.isSelected());

         // for checkBox

         List<WebElement> webCheckBox = driver.findElements(By.xpath("//input[@type='checkbox']"));

         for (WebElement e : webCheckBox) {
             e.click();
             Assert.assertTrue(e.isSelected());
             Thread.sleep(10000);
         }
