无法使用 java 在 IE 中获取新打开的 window 的句柄
Unable to get the handle of a newly opened window in IE using java
我在我的代码 "Go" 中单击一个按钮,它会打开一个新的 window。
当我检查任务管理器时,我可以看到 IE 的实例为 2,但是 getWindowHandles()
无法获取新打开的 window 的句柄,而只是 returns 父 window处理。
我用来执行此操作的代码是:
SeleniumUtils.clickOnElement(webDriver, By.xpath("//input[@name='Go' and @value='Go']"), "Click on Go", reporter);
SeleniumUtils.waitLoading(SeleniumUtils.WAIT_LONG);
List<String> windowsList = new ArrayList<>();
String parentWindow = webDriver.getWindowHandle();
windowsList.add(parentWindow);
String emailWindow = SeleniumUtils.changeDriverToTheNewWindow(webDriver, windowsList, windowsList.size()+1);
windowsList.add(emailWindow);
要改成新的window,我写了一个函数:
public static String changeDriverToTheNewWindow(WebDriver webDriver, List<String> previousWindows, int numberOfWindows) {
try {
JavascriptExecutor jsExecuter = (JavascriptExecutor) webDriver;
Set<String> windows = Collections.emptySet();
try
{
WebDriverWait wait = new WebDriverWait (webDriver, 5);
wait.until(ExpectedConditions.numberOfWindowsToBe(numberOfWindows));
windows = webDriver.getWindowHandles();
}catch(Exception e) {
lLogger.error("Error getting the window handles.", e);
windows = webDriver.getWindowHandles();
}
for (String windowId : windows) {
if (!previousWindows.contains(windowId)) {
webDriver.switchTo().window(windowId);
jsExecuter.executeScript("window.focus");
//changeDriverToWindow(webDriver, windowId);
return windowId;
}
}
} catch (Exception e) {
lLogger.error("Error changing driver to the new window!", e);
}
return null;
}
打开window的HTML&JS代码是:
<td class="xyz-column">
<link href="../Content/css/XYZ.css" rel="stylesheet" type="text/css">
<script type="text/javascript">
function onMouseOver(control) {
control.src = '../Content/images/lookup.png';
}
function onMouseOut(control) {
control.src = '../Content/images/btn_lookup.png';
}
</script>
<span class="xyz-link" id="body_XYZSelector_XYZLookup_LookupName" style="width: 175px; height: 18px; display: inline-block;" onclick="OpenXYZ(GetCurrentLookupId(this),'42e7a262-36ef-e911-80f1-005056aea4ce','10001'); return false;"> SHARANA </span>
<img class="xyz-lookup" id="body_XYZSelector_XYZLookup_LookupImage" onmouseover="onMouseOver(this);" onmouseout="onMouseOut(this);" onclick="OpenLookUp(this);" alt="Browse" src="../Content/images/btn_lookup.png" entitytype="xyz">
<input name="ctl00$body$XYZSelector$XYZLookup$LookupHiddenId" id="body_XYZSelector_XYZLookup_LookupHiddenId" type="hidden" value="56765">
<input name="ctl00$body$XYZSelector$XYZLookup$LookupHiddenName" id="body_XYZSelector_XYZLookup_LookupHiddenName" type="hidden" value="SHARANA">
<input name="ctl00$body$XYZSelector$XYZLookup$LookupHiddenId" id="body_XYZSelector_XYZLookup_LookupHiddenId" type="hidden" value="fd878f2b-90a2-4bf0-8a00-daa007b64b7d">
</td>
我找到了解决问题的办法。只要确保按照@DebanjanB 回答的 Solution 中看到的所有步骤进行操作即可。
更具体地说,在我的例子中是
...
InternetExplorerOptions options = new InternetExplorerOptions();
options.merge(cap);
WebDriver driver = new InternetExplorerDriver(options);
如您在 和
中所见
ieCapabilities.setCapability("requireWindowFocus", false);
如您所见
加上这两个后,驱动就可以正确获取到window的句柄了。
