新浏览器选项卡打开，在 SELENIUM WEBDRIVER JAVA 后找不到 WebELements

Question

我正在运行以下方法：

public void AssertPreviousSubmissionClick() throws InterruptedException{
    EnterLoginCredentials();
    PreviousSubmissionClick();  //After this action takes place a new Browser Tab Opens
    Assert.assertTrue("Clicking the link didn't work!",oldLogo.isDisplayed());
    Reporter.log("PASSED! User Successfully click the Previous Year(s) Submission Request and was taken into the Grant Process!");
}

我在 PreviousSubmissionClick() 处留下了一条注释，此时新的浏览器选项卡已打开。此时，在该方法中，我无法再在打开的新浏览器选项卡上识别 WebElements。请建议我如何在新的浏览器选项卡上找到 WebElements。

Answer 1

您需要将焦点切换到新选项卡

String currentTab = driver.getWindowHandle();
for (String tab : driver.getWindowHandles()) {
    if (!tab.equals(currentTab)) {
        driver.switchTo().window(tab); 
    }       
}
// do something on new tab

并关闭新选项卡并切换回来

driver.close();
driver.switchTo().window(currentTab);
