Question

我正在尝试设置搜索框的值，单击搜索按钮并解析结果。问题是结果显示在另一个框架中，我无法获得另一个框架。代码：

          HtmlPage page = null;
          String url = "http://www.ravmilim.co.il/naerr.asp";

          WebClient webClient = new WebClient(BrowserVersion.FIREFOX_3_6);
          webClient.setThrowExceptionOnScriptError(false);

          try

              } catch (Exception e) { 
                  //

              framePage.getAnchorByHref("logout.asp").click();

              webClient.closeAllWindows();

               e.printStackTrace();

       }    
    }

Answer 1

您可以尝试使用下一个代码获取该帧：

HtmlPage framePage = (HtmlPage)pageAfterLogin.getFrameByName("your_frame_name").getEnclosedPage();

获取框架的源代码后，您可以在此页面中获得html元素（就像您在登录页面上所做的那样）。

Answer 2

您可以尝试此示例（取自http://htmlunit.sourceforge.net/frame-howto.html）

final WebClient client = new WebClient();
final HtmlPage mainPage = client.getPage("http://htmlunit.sourceforge.net/apidocs/index.html");

获取第一帧的页面（在左上角）并单击第六个链接：

final HtmlPage packageListPage = (HtmlPage) mainPage.getFrames().get(0).getEnclosedPage();
packageListPage.getAnchors().get(5).click();

获取名为“packageFrame”的框架页面（左下角），然后点击第二个链接：

final HtmlPage pakcagePage = (HtmlPage) mainPage.getFrameByName("packageFrame").getEnclosedPage();
pakcagePage.getAnchors().get(1).click();

获取名为“classFrame”的框架页面（右侧）：

final HtmlPage classPage = (HtmlPage) mainPage.getFrameByName("classFrame").getEnclosedPage();

HtmlUnit无法获取帧内容
