我在一个网站上有一个下拉列表，当单击一个选项时，它使用 javascript 导航到新的配置文件。问题是，我不认为 HtmlUnit 的选项是单击下拉框中的选项，只是选择它，所以它永远不会导航到新页面。我知道它正在找到正确的下拉元素，因为我已经在网页的源代码中确认了它。我也在使用 getOption() 并使用下拉框的索引 4，所以 getOption(4)，但这可能是个问题？我也尝试过按值和 id，但这似乎是唯一不会给我错误的方法。我还添加了一个 Thread.sleep 以确保它有时间导航到下一页，以防万一出现问题，但我认为它没有帮助。所以总结一下，我需要它物理地点击其中一个选项以便它导航，
这是我的 HtmlUnit 代码：
public static void changeIntensity(String value) throws IOException {
try {
final WebClient webClient = new WebClient(BrowserVersion.CHROME);
DefaultCredentialsProvider creds = new DefaultCredentialsProvider();
creds.addCredentials(Main.USERNAME, Main.PASSWORD);
webClient.setCredentialsProvider(creds);
final HtmlPage page = webClient.getPage("http://192.168.1.30/profiles.sht"); // nav to profiles
System.out.println("Logged into AquaController.");
HtmlSelect select = (HtmlSelect) page.getElementByName("profileSel"); // this is for sure correst, i checked in profiles.asp == also, i tried a diff one and it said out of range, so this is correct.
System.out.println("Selected profile dropdown box.");
HtmlOption option = select.getOption(4); // select blue 20 (its profule #12) - no use getOptionByText
select.setSelectedAttribute(option, true);
System.out.println("Selected option.");
System.out.println("Thread sleeping for 5");
Thread.sleep(5000);
System.out.println("Thread done sleeping for 5");
HtmlInput pMin = page.getElementByName("profileLMin"); // min intensity - name =
HtmlInput pMax = page.getElementByName("profileLMax"); // max intensity
pMin.click();
pMin.setValueAttribute(value);
pMax.click();
pMax.setValueAttribute(value);
HtmlElement updateProfile = page.getElementByName("Update");
updateProfile.click();
System.out.println("finished");
}
catch (InterruptedException e) {
e.printStackTrace();
}
}
