硒:如何从选择菜单中选择一个选项?

问题描述：

我正在使用PHPUnit Selenium扩展用PHP编写Selenium测试.

I am writing a Selenium test in PHP using the PHPUnit Selenium extension.

我知道如何在文本字段中输入内容:

I know how to type something into a text field:

$this->type('fieldName', 'value');

但是如何从下拉菜单中选择一个选项?

But how do I select an option from a drop-down menu?

答

要扩展其他(准确的)答案，可以根据选项的标签，值，id或索引进行选择.摘自 http://release.seleniumhq.org/selenium-core上的官方参考/1.0/reference.html :

To expand on the other (accurate) answers, you can select based on the label, value, id, or index of the options. From the official reference available at http://release.seleniumhq.org/selenium-core/1.0/reference.html:

选择(selectLocator，optionLocator)

参数:

selectLocator-标识下拉菜单的元素定位器
optionLocator-选项定位器(默认为标签)

使用选项定位器从下拉菜单中选择一个选项.

Select an option from a drop-down using an option locator.

选项定位器提供了不同的方式来指定HTML Select元素的选项(例如，用于选择特定选项或断言所选择的选项满足规范).选择选项定位器有几种形式.

Option locators provide different ways of specifying options of an HTML Select element (e.g. for selecting a specific option, or for asserting that the selected option satisfies a specification). There are several forms of Select Option Locator.

标签 = labelPattern :根据其标签(即可见文本)匹配选项. (这是默认设置.)
- label = regexp:^ [Oo] ther
- label=labelPattern: matches options based on their labels, i.e. the visible text. (This is the default.)
  - label=regexp:^[Oo]ther
  - value = other
  - id = option1
  - index = 2
  如果未提供选项定位符前缀，则默认行为是在标签上匹配.
  
  If no option locator prefix is provided, the default behaviour is to match on label.
