我有一個網站上的下拉列表，當點擊一個選項時，使用javascript導航到新的配置文件。問題是，我不認爲HtmlUnit的Option在下拉框中點擊選項，只選擇它，所以它不會導航到新頁面。我知道它正在找到正確的下拉元素，因爲我已經在網頁的源代碼中確認了它。我也使用getOption（）和使用索引4的下拉框，所以getOption（4），但這可能是一個問題？我也嘗試了值和ID，但這似乎是唯一不會給我一個錯誤的方法。我還添加了一個Thread.sleep，以確保它有時間導航到下一個頁面，以防出現問題，但我認爲它沒有幫助。因此，爲了包裝起來，我需要它實際點擊其中一個選項才能導航，但click（）似乎不起作用？HtmlUnit Java - HtmlOption未正確選擇選項
這裏是我的代碼的HtmlUnit：
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();
}
}
這裏是有關網站源：
<div id='title'>
<br>
<h2>Apex Profile Setup</h2>
<br>
</div>
<script type="text/javascript">
leafHeight = 220;
//if (window.addEventListener){
// window.addEventListener("load", autoInit, false);
//}
//else if (window.attachEvent){
// window.attachEvent("onload", autoInit);
//}
function autoInit()
{
var selector = document.getElementsByName("profileTypeSel");
showLeaf(1, selector[0].selectedIndex+1);
init();
}
function updatepSelect() {
document.pSelect.submit("profiles.sht");
}
