得到以下 Html block ...

<div style="visibility:visible" id="stateProvinceDiv">
  <div id="stateUSALabelDiv"><label for="stateUSAIdSelect">Find Your Bookstore</label></div>
    &nbsp;<select size="1" id="stateUSAIdSelect" name="stateUSAId">
      <option>Loading...</option>
    </select>
</div>

选择的页面/内容是由 javascript 函数/调用生成的...我可以获取该页面，因此我得到了一个 HtmlPage 实例。

鉴于我不知道如何获取选择/选项DOM 中有一个“form”元素。指向代码块的指针处理这个问题将不胜感激。

实际的 Html 如下:

最佳答案

您可以使用原型(prototype)和选择的 id 来获取选择。

$('stateUSAIdSelect');

或者带有 css 规则的选项

$$('#stateUSAIdSelect option');

您实际上想用它们做什么？

更新:

抱歉，我误解了我想的问题。您想弄清楚如何使用 htmlunit 测试这些元素？

要获取选择，您可以使用getHtmlElementById

page.getHtmlElementById("stateUSAIdSelect");

从那里您可以调用 getChildNodes 从选择中获取所有选项。

htmlunit 的 javadoc 概述了您也应该能够使用的一大堆其他方法 http://htmlunit.sourceforge.net/apidocs/index.html .

希望有帮助。
