问题描述

如何从下拉列表中获取所有元素?我使用了下面的代码:

How can I get all elements from a drop down list? I used the code below:

List<WebElement> elements = driver.findElements(By.id("s"));

但我总是只得到第一个元素.

But I am always getting the first element only.

推荐答案

bindigs 中有一个专门为此设计的类.

There is a class designed for this in the bindigs.

您正在寻找 Select 类:

https://code.google.com/p/selenium/source/browse/java/client/src/org/openqa/selenium/support/ui/Select.java

您需要找到"实际的 select 元素，而不是单个选项.找到那个 select 元素，让 Selenium &Select 类为您完成剩下的工作.

You would need to 'find' the actual select element, not the individual options. Find that select element, and let Selenium & the Select class do the rest of the work for you.

您会寻找类似的东西(s 是实际的 select 元素):

You'd be looking for something like (s being the actual select element):

WebElement selectElement = driver.findElement(By.id("s");
Select select = new Select(selectElement);

Select 类有一个方便的 getOptions() 方法.这将完全按照您的想法执行.

The Select class has a handy getOptions() method. This will do exactly what you think it does.

List<WebElement> allOptions = select.getOptions();

现在你可以用 allOptions 做你想做的事.

Now you can do what you want with allOptions.
