Select多选框下拉列表
Select多选框下拉列表
在做自动化的过程中,我们经常会遇到select标签类型的多选框下拉列表。针对select标签类型,selenium中有封装好的API可以使用,接下来,我们一起看看关于select多选框下拉列表的操作方法吧。
操作方法简介
1、选择下拉列表方法
selectByIndex(index); // 根据索引选择
selectByValue(value); // 根据value属性选择
selectByVisibleText(text); // 根据选项文本值选择
注意:
index是从0开始的
Value是option标签的一个属性值,并不是显示在下拉框中的值
VisibleText是在option标签中间的值,是显示在下拉框的值
2、取消方法
deselectByIndex(index); // 根据索引取消
deselectByValue(value); // 根据value属性取消
deselectByVisibleText(Text); // 根据选项文本值取消
deselectAll(); // 取消所有选中
3、其他方法
getAllSelectedOptions(); // 获取所有被选中的标签元素对象集合
getFirstSelectedOption(); // 获取第一个被选中的标签元素对象
select.getOptions(); // 获取所有选项的标签元素对象集合
getWrappedElement(); // 获取包裹具体选项的元素对象
isMultiple(); // 判断该元素是否支持多个对下个,根据mutiple属性来判断,返回布尔值

代码操作
1、选择下拉列表
@Test
public void testDemo1() throws InterruptedException {
WebDriver driver = new ChromeDriver();
driver.get("E:\\Notes\\Selenium\\select.html");
driver.manage().window().maximize();
Thread.sleep(3000);
WebElement element = driver.findElement(By.id("select_province"));
Select select = new Select(element);
// 选择索引值为2,即第三个选项
select.selectByIndex(2);
Thread.sleep(5000);
// 选择value属性值为1的选择
select.selectByValue("1");
Thread.sleep(5000);
// 选择文本值为安徽省的选项
select.selectByVisibleText("安徽省");
Thread.sleep(5000);
}
2、取消方法
取消方法针对的select标签是需要有multiple属性的,没有则抛异常。
在上面html中的select标签中增加multiple="multiple"
<select id="select_province" name="select_name" class ="select_province_class" multiple="multiple">
<select id="select_city" name="select_name" class ="select_city_class" multiple="multiple">
@Test
public void testDemo2() throws InterruptedException {
WebDriver driver = new ChromeDriver();
driver.get("E:\\Notes\\Selenium\\select_mutiple.html");
driver.manage().window().maximize();
Thread.sleep(3000);
WebElement element = driver.findElement(By.id("select_city"));
Select select = new Select(element);
// 索引值为2的选择后取消
select.selectByIndex(2);
Thread.sleep(3000);
select.deselectByIndex(2);
Thread.sleep(3000);
// value属性值为1的选择后取消
select.selectByValue("1");
Thread.sleep(3000);
select.deselectByValue("1");
Thread.sleep(3000);
// 选择文本值为安徽省的选项,然后取消
select.selectByVisibleText("滁州市");
Thread.sleep(3000);
select.deselectByVisibleText("滁州市");
// 取消所有
select.deselectAll();
Thread.sleep(3000);
}
3、其他方法
@Test
public void testDemo() throws InterruptedException {
WebDriver driver = new ChromeDriver();
driver.get("E:\\Notes\\Selenium\\select.html");
driver.manage().window().maximize();
Thread.sleep(3000);
WebElement element = driver.findElement(By.id("select_province"));
Select select = new Select(element);
boolean multiple = select.isMultiple();
System.out.println("multiple is " + multiple);
System.out.println("================================================");
WebElement wrappedElement = select.getWrappedElement();
System.out.println("wrappedElement is " + wrappedElement.getText());
System.out.println("================================================");
List<WebElement> options = select.getOptions();
System.out.println("The size of allSelectedOptions is " + options.size());
for(int i=0;i<options.size();i++) {
System.out.println("第"+ i +"次:" + options.get(i).getText());
}
System.out.println("================================================");
WebElement firstSelectedOption = select.getFirstSelectedOption();
System.out.println("firstSelectedOption is " + firstSelectedOption.getText());
System.out.println("================================================");
List<WebElement> allSelectedOptions = select.getAllSelectedOptions();
System.out.println("The size of allSelectedOptions is " + allSelectedOptions.size());
for(int i=0;i<allSelectedOptions.size();i++) {
System.out.println("第"+ i +"次:" + allSelectedOptions.get(i).getText());
}
driver.quit();
}
